The Chamberlain RJO101 is a wall-mount Wi-Fi opener with battery backup — it mounts beside the door, clears the ceiling, and keeps running when the power's out. We install the RJO101 for East Valley homeowners who want that space-saving setup, and we service the wall-mount hardware, battery, and logic board on the ones already in Phoenix-area garages.
If your Chamberlain RJO101 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 Chamberlain RJO101 on your garage? Here's how Farnsworth handles it.
You don't need to track down the Chamberlain RJO101 yourself. We stock and source Chamberlain openers for our clients and bring the right one to your home.
Wall-mount openers like the Chamberlain RJO101 mount beside the door instead of on the ceiling — a cleaner install that frees up overhead space, but one that demands correct torsion-bar mounting and cable tension.
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.
