LiftMaster is the #1 brand of professionally installed residential, commercial and gate opener systems.
The LiftMaster 4690L is a heavy-duty DC chain-drive opener with an integrated camera and battery backup — durable hardware with modern eyes-on-the-garage features. Farnsworth installs the 4690L across Phoenix and the East Valley, and when an existing one needs a chain re-tensioned, a camera realigned, or a battery replaced, we keep those parts on the truck.
If your LiftMaster 4690L is acting up, here's what we see most often — and we repair every one of these as part of our garage door opener repair & replacement service across the Phoenix area. Call us at (602) 935-9766 and we'll get it sorted.
Thinking about putting a LiftMaster 4690L on your garage? Here's how Farnsworth handles it.
You don't need to track down the LiftMaster 4690L yourself. We stock and source LiftMaster openers for our clients and bring the right one to your home.
Chain drives are durable and forgiving, but chain tension and rail alignment matter. We set the LiftMaster 4690L up so it runs smoothly from day one.
We balance the door, set the travel limits and force, test the safety reverse, program your remotes and the myQ app, and walk you through everything before we leave.
