Garage Door Opener Not Working After a Power Surge?
We can usually tell what the weather did last night by what the phone does the next morning. A monsoon cell moves through Gilbert or Queen Creek in the evening, and by nine the following day we're taking calls about openers that are dead, openers that work from the wall but not the remote, and openers that have decided to do something entirely of their own invention. Surges do a range of things to an opener, and the range matters, because two of the outcomes cost you nothing to put right and one of them is the most expensive part in the unit. Work through them in order and you'll know which you've before you pick up the phone.
This is general guidance based on what we see on service calls — it isn’t a substitute for someone looking at your actual door. Every door is a little different, and if anything here feels beyond what you want to take on, stop and give us a call.
What to check in the next 10 minutes
Four checks, in this order. Don't skip the first one — it's free, it's the most common answer, and the reset is very often not where people look for it.
-
1Find and reset the GFCI
Openers are usually on a ground fault circuit, and a surge trips them readily. The catch is that the reset button is frequently not at the ceiling receptacle the opener plugs into — it can be on a different outlet in the garage, on an exterior outlet, in a bathroom, or on a panel-mounted breaker. Walk the garage and the adjacent outlets looking for a small Reset button.
You’ll know it worked when: You've pressed a Reset button and felt it click in, and the opener light or panel has come back.
-
2Check the breaker properly
A tripped breaker doesn't always sit obviously between on and off. Switch the suspect breaker fully off, then fully on again, rather than just nudging it. While you're there, note whether anything else in the garage lost power at the same time.
You’ll know it worked when: The breaker has been fully cycled and either the opener came back or it definitely didn't.
-
3Confirm the outlet itself is live
Plug a lamp or a phone charger into the ceiling receptacle. If nothing works there, the problem is upstream of the opener and no amount of opener troubleshooting helps. This one step separates half of all these calls into a different category.
You’ll know it worked when: You've proved the outlet is either live or dead, rather than assuming.
-
4Establish what still works
Does the opener light come on? Does the wall button do anything? Do the two sensor lights near the floor still glow? Does the remote do nothing at all, or does it click the opener without moving the door? Each answer narrows this a long way, and it's worth writing down before you call anyone.
You’ll know it worked when: You can list what responds and what doesn't.
Dead, or alive and wrong?
Surge damage splits into two very different pictures, and which one you've decides where you start.
If the opener is erratic and there's any burning smell, stop here and unplug it. Partial board damage that's dissipating heat is the one version of this that shouldn't be left plugged in while you troubleshoot.
What the storm actually took
Match the behavior to the likely damage. Several of these cost nothing to put right.
Power supply first — GFCI or breaker. Then the transformer.
Jump to that fix ↓The radio receiver or the stored pairings. Often just needs reprogramming.
Jump to that fix ↓Travel limits were scrambled and need resetting.
Jump to that fix ↓The sensors or their circuit took the surge along the low-voltage wiring.
Jump to that fix ↓Partial board damage. The hardest version to pin down and the most likely to get worse.
Jump to that fix ↓Battery backup took over during the outage and its battery is now flat or finished.
Jump to that fix ↓The router changed rather than the opener. Reconnect rather than replace.
Jump to that fix ↓What a surge does to an opener
A surge is a brief spike of voltage far above what the circuit normally carries, and it arrives in a fraction of a second. Lightning gets the blame, but the more frequent sources are less dramatic: the utility switching load during a storm, a transformer restoring power after an outage, and the moment large equipment on the same feeder starts or stops. Restoration surges are why openers so often fail when the power comes back rather than when it goes out.
Inside your opener, the parts that matter aren't equally tough. The motor is a lump of copper and steel and shrugs off most of this. The logic board isn't — it runs on low-voltage direct current supplied by a small transformer, and its components are built to tolerances measured in volts rather than hundreds of volts. So the usual casualty order is transformer first, board second, motor almost never.
There's a second path people miss. Every low-voltage wire in the garage is an antenna, and a nearby strike can induce a spike in the sensor wiring and the wall control wiring without ever touching the mains. That's why a storm sometimes takes out the photo eyes or the wall button while leaving everything else alone.
The good news is that a lot of what looks like damage isn't. Boards are computers, and computers hold state. A spike can scramble stored settings without harming a single component — pairings wiped, travel limits forgotten, force values reset to defaults. Those cost nothing but time to restore, and they're a genuinely common outcome, which is why it's worth working through them before assuming the worst.
So the sequence is: prove the power first, restore anything that was merely scrambled second, and only then start talking about parts. Getting that order wrong is how people end up replacing openers that needed a reset button pressed.
Reading what survived
What still works after a storm is the most useful diagnostic information you've.
| What you’re seeing | Most likely cause | How urgent | Who should fix it |
|---|---|---|---|
| Totally dead, other garage outlets also dead | Tripped breaker or GFCI upstream | Today | You can do this |
| Totally dead, other outlets fine | GFCI on the opener circuit, or the transformer is gone | Today | Either — call us if unsure |
| Light works, motor does nothing | Board's motor circuit damaged | This week | Call a pro |
| Wall button works, no remote does | Radio receiver damaged, or pairings wiped | This week | You can do this |
| Runs but stops short or reverses at the floor | Travel limits or force settings scrambled | This week | Either — call us if unsure |
| Won't close, sensor lights dark or wrong | Sensors or sensor circuit hit through the low-voltage wiring | Fix today — door is unusable | Either — call us if unsure |
| Random operation, or opening on its own | Damaged board firing outputs unpredictably | Unplug it now | Call a pro |
| Beeping continuously since the storm | Battery backup discharged during the outage, or the battery is finished | This week | You can do this |
| Door fine, app and Wi-Fi gone | Router or network changed during the outage, not opener damage | Whenever | You can do this |
| Works intermittently with no pattern | Partial board damage — usually worsens | This week | Call a pro |
| Any burning smell alongside the fault | Something damaged is dissipating heat | Unplug it now | Call a pro |
What’s actually causing it
These are ordered the way we work through them on a real service call — cheapest and most common first, so you don’t start by replacing a part that was never the problem.
The GFCI or breaker tripped and nothing is actually damaged
Basic checkThis is the best outcome and the most common one, and it's worth being genuinely thorough about before considering anything else. Ground fault outlets are sensitive by design, and the transient during a storm or a restoration is exactly the sort of event that trips them. The frustration is that the reset is often nowhere near the opener. Circuits get wired in ways that make sense to an electrician and to nobody else, so a garage ceiling receptacle can be protected by a GFCI on an exterior wall, in a bathroom, or on a breaker in the panel.
How you can tell: The opener is completely lifeless — no light, no panel, no click, nothing. Frequently something else in the garage is dead too, which is a strong hint. There's no smell, no noise, and no sign of anything having happened at the unit itself.
- Walk every outlet in the garage looking for Test and Reset buttons. Press Reset firmly until it clicks in.
- Check exterior outlets, and any bathroom on the other side of the garage wall. Bathroom GFCIs protecting garage circuits are more common than they should be.
- Open the panel and look for a breaker with a Test button on it, which is a GFCI breaker doing the same job from a different place.
- Switch the suspect breaker fully off and fully on, rather than nudging it back from the middle position.
- Plug a lamp into the ceiling receptacle to confirm whether it's live before you conclude anything about the opener.
You’ll know it’s right when: The ceiling receptacle powers a lamp, and the opener's light or panel has come back to life.
The transformer took the hit
High risk — call a technicianThe small transformer that steps mains voltage down for the control electronics is usually the first casualty in a surge, because it sits directly in the path and it's the least robust thing there. When it fails the opener is completely dead in a way that looks identical to a tripped breaker from the floor — which is exactly why the power checks come first. In some designs the transformer is a separate replaceable part, and in others it's on the board and the board is the repair.
How you can tell: The receptacle is proven live, every breaker and GFCI is confirmed good, and the opener still shows nothing at all. No light, no beep, no response from the wall panel.
The logic board is damaged
High risk — call a technicianThe board is the opener's brain, and it's the component surges damage most consistently after the transformer. It handles the radio, the safety circuit, the travel limits, the light, and the relays that drive the motor. Damage is rarely tidy — one subsystem can fail while everything else carries on, which produces the strange partial faults people describe after a storm: a light that works while the motor doesn't, a wall button that responds while no remote does, an opener that runs one direction only.
How you can tell: Something works and something else definitely doesn't, the power supply has been proven good, and reprogramming and limit resetting haven't fixed it. Behavior is often inconsistent between attempts.
The remotes, keypad, or Wi-Fi lost their pairings
Basic checkThis is the outcome people most often mistake for hardware damage, and it's free to fix. Rolling-code openers store their paired devices in memory on the board, and a voltage transient can corrupt or clear that memory without harming a single component. The opener is fine; it has simply forgotten who it's allowed to listen to. The same goes for stored network details on a Wi-Fi opener — although in that case it's just as likely your router came back from the outage with a changed configuration and the opener is fine on both counts.
How you can tell: The wall button works perfectly, the door runs normally when you use it, and remotes or the keypad do nothing at all. On smart openers, the door works while the app reports it offline.
- Confirm lock mode is off at the wall panel first — a Lock indicator lit will produce identical symptoms and costs nothing to rule out.
- Change the remote battery before assuming anything. It's cheap and it removes a variable.
- Find the Learn button on the opener head, usually under the light cover, and note its color.
- Press and release Learn — don't hold it, since holding erases everything — then press the remote button within about thirty seconds until the opener light flashes or clicks.
- Repeat for every remote, the keypad, and any vehicle button, since a wiped memory takes all of them.
- For a Wi-Fi opener, check whether the router's network name or password changed during the outage before you reconfigure the opener.
You’ll know it’s right when: Every remote and the keypad operate the door reliably from their normal distance.
The travel limits or force settings got scrambled
Hands-on — moderate riskOpeners store where fully open and fully closed are, and how much resistance to push through before assuming they have hit something. Those values live in the same memory the pairings do, and a transient can corrupt them or throw them back to factory defaults. The result is a door that runs but gets the geometry wrong: stopping short of the floor, reversing on contact, opening only partway, or straining at the top of its travel.
How you can tell: The opener responds normally and the motor runs properly, but the door stops in the wrong place or reverses when it shouldn't. Nothing mechanical has changed and the timing lines up exactly with the storm.
- Check the door runs freely by hand first. Pull the release with the door closed and lift — it should feel like around ten pounds and hold where you stop it. A limit problem and a spring problem look similar and this separates them.
- Find the limit controls. Newer units use buttons behind a panel or under the light cover; older ones use plastic adjustment screws marked with arrows or up and down.
- Re-run the limit-setting routine from your manual for your specific model. Guessing at the sequence is how people end up worse off than they started.
- Adjust in small increments and test between each one rather than making a large change and hoping.
- Run the safety reversal test afterwards without exception: lay a 2x4 flat on the floor directly under the center of the door, running across the opening in the door's path and confirm the door reverses when it meets the board.
- If the door won't reverse on the 2x4, reduce the down force and test again until it does.
You’ll know it’s right when: The door seats fully on the floor without straining, opens to its full height, and reverses promptly on the 2x4.
The safety sensors or their circuit took the surge
Hands-on — moderate riskThis is the path through the low-voltage wiring rather than the mains. Sensor wire runs the length of the garage wall, which makes it a reasonable antenna for a nearby strike, and the spike it picks up goes straight to the sensor electronics and the board's sensor input. Either end can fail. The result is an opener that runs happily in the up direction and refuses to close, because under UL 325 it must positively confirm the beam before it will close and it can no longer do that.
How you can tell: The door opens normally and won't close, or closes only while you hold the wall button. One or both sensor lights are dark, dim, or blinking. On a LiftMaster or Chamberlain the opener light blinks a sensor code, most often one, two, four, or ten times.
- Look at both sensor lights near the floor. Both should be lit and steady.
- Clean both lenses with a soft dry cloth and re-aim each one at its partner, since a storm may simply have knocked something into a bracket.
- Check the sensor wire along its run for damage, and check both leads are seated in the terminals at the opener head.
- Count the opener's blink code and note it, because it tells you whether the board sees an open circuit, a short, or a misalignment.
- If one sensor is dark no matter how you aim it and the wiring looks sound, that sensor has most likely failed.
You’ll know it’s right when: Both sensor lights are steady and the door closes fully from a remote rather than only while you hold the wall button.
It works, then it doesn't — partial board damage
High risk — call a technicianThe most frustrating outcome, and the one that costs people the most in wasted effort. A surge can damage a component without destroying it, leaving it marginal. The opener then works when it's cool, or when the load is light, or on alternate Tuesdays, and every fix appears to work briefly before the fault returns. People chase remotes, sensors, and wiring for weeks because each of those does temporarily seem to help.
How you can tell: The behavior is inconsistent in a way that doesn't correlate with anything — not temperature, not time of day, not which control you use. It started at the storm and has been getting gradually worse rather than staying stable.
The battery backup carried the outage and is now finished
Basic checkIf your opener has battery backup, it did its job during the outage and it may have paid for it. These batteries give around 20 cycles before it's spent, which matches the 20-cycle/30-hour figure the manufacturers publish, and running one flat and leaving it flat is hard on it. In this climate they last around one to three years anyway, against three to five somewhere temperate, so a storm often finishes off a battery that was already near the end. The opener then beeps to tell you, which people reasonably interpret as surge damage.
How you can tell: Continuous or periodic beeping since the storm, an indicator light on the powerhead reporting a battery fault, and a door that otherwise works perfectly on mains power.
- Give it a full day on mains power to recharge before concluding anything — a deeply discharged battery can take a while to report as healthy.
- Check the battery status indicator on the powerhead against what your manual says the colors mean.
- Note the battery's age if you know it. Past a couple of years here, replacement is more likely than recovery.
- Confirm the beeping is the opener rather than the wall console, since some consoles beep about entirely different things.
- Order the replacement battery specified for your model rather than a physically similar one.
You’ll know it’s right when: The beeping has stopped and the battery indicator reports a healthy charge.
What your opener is telling you, by brand
LiftMaster & Chamberlain
After a storm the blink code is the fastest way to find out what the board thinks it lost. Count the flashes of the main light straight after you press the button.
| What you see | What it means | What to do |
|---|---|---|
| 1 or 2 blinks | Sensor circuit open or shorted — the classic induced-spike result | Check the sensor wiring and both terminal connections — cause 6 |
| 4 blinks | Sensors marginally out of aim | Clean and re-aim both eyes until steady |
| 10 blinks | Sensors blocked or well out of line | Clear the path, then re-aim |
| 6 blinks | Motor circuit failure | Board or motor circuit — service call |
| No light at all, outlet proven live | Transformer or board power section gone | Cause 2 — this is a parts diagnosis |
| Yellow | Security+ 2.0 — the current generation | Any Security+ 2.0 remote, or a universal that lists 2.0 |
Genie
Genie reports through the Safe-T-Beam LEDs and the powerhead indicator rather than a blink count, and one of its states is regularly mistaken for storm damage when it's nothing of the sort.
| What you see | What it means | What to do |
|---|---|---|
| Both Safe-T-Beam LEDs steady red | Travel limits lost — very common after a surge, and not a sensor fault | Re-run the limit routine from your manual — cause 5 |
| Receiving eye dark | That leg has lost power, or the sensor is damaged | Check the wiring and terminals — cause 6 |
| Powerhead LED dark entirely | No power reaching the unit | GFCI and breaker first — cause 1 |
| Runs, but Intellicode remotes ignored | Stored pairings wiped | Reprogram each remote — cause 4. Genie often needs two presses where LiftMaster needs one |
What you’ll need if you’re doing this yourself
- A lamp or phone charger — the fastest way to prove whether the ceiling receptacle is actually live
- A flashlight — for reading sensor LEDs, terminal blocks, and the Learn button color
- A stepladder — for reaching the opener head, the Learn button, and the limit controls
- A fresh remote battery — removes a variable before you start reprogramming anything
- Your opener's manual — limit-setting routines vary by model, and guessing at the sequence usually makes things worse
- A scrap 2x4 — for the safety reversal test after any limit or force adjustment
Things not to do — and why
A tripped GFCI and a destroyed transformer look identical from the floor, and one of them is free to fix. We've been called out to openers that needed a reset button in a bathroom pressed.
It's detecting a fault current, which is what it exists to do. Repeated resetting asks the last protective device in the chain to keep absorbing something it was designed to interrupt.
A press and release starts pairing. Holding it for several seconds erases every remote, keypad and vehicle button on the opener, which is a bad thing to do to yourself in the middle of an outage recovery.
A partly damaged board can drive its outputs unpredictably, and an opener that operates on its own is a door that closes with nobody watching. It also may be dissipating heat somewhere nobody can see.
The low-voltage wiring is exactly the path an induced spike takes, so sensors failing after a storm is expected. They're also the system that stops the door on a person, and openers built to UL 325 won't operate normally without them anyway.
Point-of-use strips need a properly grounded receptacle to divert anything to, and many older garage circuits don't offer one. A strip on an ungrounded outlet gives you an indicator light and very little else.
Wiped pairings and reset travel limits account for a real share of these calls, and both restore for nothing. Establishing that first costs you an hour and occasionally saves you an opener.
Why monsoon season fills our schedule
This is one of the most seasonal problems we deal with. Between roughly July and September, storms move across the Valley with a mix of lightning, blowing dust, and short outages, and the calls arrive in clusters — a run through Chandler and Gilbert one evening, then a morning of dead openers along the same corridor.
The damage isn't usually caused by a direct strike, which is rare. It comes from the ordinary electrical chaos around a storm: the utility switching load, the moment power is restored to a whole neighborhood at once, and spikes induced into low-voltage wiring by strikes a street or two away. Restoration is the underrated one. An opener that survived the outage without complaint can fail in the second the power comes back, which is why people so often report that everything was fine until the lights returned.
- Restoration is the dangerous moment — more openers fail when power returns than when it goes out. Unplugging during a storm is genuinely worth the small inconvenience.
- Sensor wire acts as an antenna — a strike nearby can spike the low-voltage run without touching the mains, which is why photo eyes so often fail after a storm.
- Backup batteries are already short-lived here — roughly one to three years against three to five in a temperate climate, so an outage frequently finishes one that was nearly done.
- Dust arrives with the storm — the same cell that brings the surge films the sensor lenses, and people sometimes chase electrical damage that's actually silt on a lens.
- Summer grid load compounds it — voltage sags and recoveries on hot afternoons are harder on electronics than a single clean spike.
- Whole-home surge protection is worth it here — fitted at the panel, it protects the opener, the air conditioner, and everything else, and it's a better investment in this climate than a handful of power strips.
Getting through the next storm intact
You can't stop a surge, but you can decide how much of it reaches the opener.
- Fit whole-home surge protection at the panel — it clamps incoming spikes before they reach anything, and it covers the whole house rather than one appliance. An electrician's job, and the single most effective step on this list.
- Unplug the opener when a storm is coming through — unglamorous, free, and completely effective. Pull the release cord if you need the door moved while it's unplugged.
- Check the receptacle is properly grounded — point-of-use protection needs somewhere to divert the energy, and older garage circuits don't always provide it.
- Write down your remote programming steps — tape the sequence inside a cabinet door. Reprogramming after a wipe is far less annoying when you aren't hunting for a manual in the dark.
- Know where your GFCI reset actually is — find it on a calm day rather than at ten at night with a car stuck inside. Mark it if it's somewhere unobvious.
- Replace the backup battery on schedule — roughly every two years here, rather than waiting for it to fail during the outage you needed it for.
- Wipe the sensor lenses after a dust storm — the same weather that brings the surge brings the silt, and one of those two problems takes ten seconds to solve.
How a storm call usually unfolds
There's a normal order to this, and following it keeps people from spending money in the wrong place.
The first step catches more of these calls than every other step combined, which is why we ask about it on the phone before booking anything.
When to have us look at it
Call us if the receptacle is proven live and the opener still shows nothing, if it works erratically with no pattern, if it operates on its own, if a remote won't pair no matter what you do, or if there's any burning smell at all. That last one means unplug it first and call second.
- Confirm what's actually reaching the opener before assuming anything inside it has failed
- Test the transformer and the board's power section, which is what separates a cheap repair from an expensive one
- Check the sensor circuit end to end, since that's the path induced spikes take
- Restore travel limits and force settings to specification for your model, and prove the result
- Reprogram every remote, keypad and vehicle button that was wiped
- Test the backup battery and its charging circuit rather than replacing it blind
- Run the safety reversal test the way UL 325 requires and show you the result
- Give you a straight assessment of repair against replacement, including whether parts are still available for your model

What the number depends on
Surge calls have the widest spread of anything we attend, because the same storm can leave you with a free fix or a new opener. What decides it:
- Whether anything was actually damaged A tripped GFCI, wiped pairings, and reset travel limits are all restoration rather than repair. A meaningful share of these calls end there.
- Transformer or board On some models the transformer is a separate part. On others it's on the board, and the board is the most expensive single component in the opener.
- Whether the sensors survived Photo eyes are replaced as a pair, and it's a modest job. The wiring behind them is the variable, particularly if a run needs replacing. Re-running a damaged length of wire is where a surge-season garage door opener repair usually gains its time.
- How old the unit is Past about fifteen years, a board replacement rarely represents good value against a new opener with battery backup, rolling-code security and a warranty.
- Parts availability for your model Boards for discontinued openers are sometimes obtainable and sometimes not, and that changes the decision more than the price of the part does.
- Whether an electrician needs to be involved A GFCI that trips repeatedly, a receptacle with arcing damage, or an ungrounded circuit is electrical work rather than garage door work, and we'll say so rather than working around it.

Questions we get asked about this
Yes, and the logic board and its transformer are the usual casualties because they run on low-voltage electronics with very little tolerance for a spike. The motor is rarely affected. What surprises people is how often nothing is damaged at all — a tripped GFCI, wiped remote pairings, or scrambled travel limits produce symptoms that look like a dead opener and cost nothing to put right.
Start with the power supply rather than the opener. Ground fault outlets trip readily during storms and their reset button is often on a different outlet entirely, sometimes in a bathroom or outside. Plug a lamp into the ceiling receptacle to prove whether it's live. If the outlet is good and the opener still shows no sign of life, the transformer or the board's power section has taken the hit. Either of those is a garage door opener repair rather than a part you'd want to buy blind.
The opener stores its paired devices in memory on the logic board, and a voltage transient can clear or corrupt that memory without damaging anything. The fix is reprogramming each remote at the Learn button — press and release it, never hold it, then press the remote within about thirty seconds. Check lock mode at the wall panel first, since that produces identical symptoms for free.
Almost certainly the travel limits were scrambled. Those values live in the same memory the remote pairings do, and a spike can throw them to defaults or corrupt them. Re-run the limit-setting routine from your manual for your specific model, then run the 2x4 safety reversal test afterwards. Check the door lifts easily by hand first, because a heavy door produces the same symptom for an entirely different reason.
It's the most effective thing you can do and it costs nothing. The riskiest moment isn't the outage but the restoration, when power comes back to a whole neighborhood at once, so unplugging before the storm and leaving it unplugged until things settle is worth the inconvenience. Pull the red release cord if you need to move the door in the meantime.
A whole-home device fitted at the electrical panel is the version that genuinely helps, because it clamps the spike before it reaches anything in the house. A plug-in strip at the ceiling receptacle is better than nothing but depends on that outlet being properly grounded, which isn't a given in older garages. Neither protects against a spike induced directly into the sensor wiring.
The sensor wire runs the length of the garage wall and makes a reasonable antenna, so a nearby strike can spike the photo eyes or the board's sensor input without ever coming through the mains. Under UL 325 the opener must positively confirm the beam before it will close, so a damaged sensor circuit means a door that opens and refuses to close. Check both sensor lights and count the opener's blink code.
The pattern to look for is partial function that doesn't respond to anything you try. If the power supply is proven good, the remotes have been reprogrammed, the limits have been reset, and the opener still behaves inconsistently, the board is the remaining candidate. Boards aren't practically repairable at component level, so the real question becomes whether replacing it makes sense for the age of the unit.
That's usually the battery backup rather than surge damage. The battery carried the outage, discharged, and is now reporting that it's flat or finished. Give it a full day on mains power to recharge before concluding anything. In this climate these batteries last roughly one to three years, so an outage often just finishes off one that was already near the end.
It depends almost entirely on what failed and how old the unit is. Sensors, a battery, or restoring wiped settings is straightforward at any age. A board on a unit past about fifteen years usually isn't worth it, because the part is the most expensive one in the opener and a modern replacement brings battery backup, current safety features and a warranty for a comparable spend. We'll give you the reasoning rather than just the recommendation.
That's the signature of partial board damage — a component that was weakened rather than destroyed, and now works when it's cool or lightly loaded and not otherwise. It's the most frustrating outcome because every fix appears to help briefly. It also tends to get worse rather than settling, and if the opener has started operating on its own, unplug it until somebody has looked at it.
Probably not. If the door itself runs normally from the wall button and the remotes, the opener's control side is fine and only the Wi-Fi connection is missing. Routers frequently come back from an outage with a changed configuration, or with the 2.4 GHz band merged into a single network the opener can't pick out. Check the router before you assume the opener's radio was damaged.
