RJO101 is Chamberlain's compact wall-mount / jackshaft-style smart opener. Official current RJO parts support identifies the 2023+ platform with a yellow Learn button; the product family includes battery backup, Wi-Fi/myQ, remote LED lighting and an automatic door lock.
Confirm this is the opener you have
Use several source-backed clues together. The motor-unit label remains the strongest identity clue.
Use the full motor-unit label for model identity; do not identify from opener case shape alone.
Use this as a cross-check, not as a substitute for the model label.
This changes power-outage diagnosis and helps separate nearby models.
Keep network/connectivity diagnosis separate from physical door movement.
Use the active receiver or Learn-button generation before ordering a remote.
Model specifications that matter for troubleshooting
Remote / accessory evidence tied to this model
These rows come from the verified compatibility dataset. An added external receiver can still change the active radio path.
Exact model: current RJO wall-mount family with yellow Learn-button evidence; verify the current yellow-compatible Chamberlain accessory row
Chamberlain current 2023+ RJO parts identify a yellow Learn button and explicitly list RJO101. Preserve any added receiver separately before buying a remote.
Wall-control compatibility for this model
Wired controls follow the opener logic/control interface. Wireless wall consoles follow the active radio receiver.
Genie Universal Wireless Wall Console
Because this console is wireless, an external receiver can change compatibility even though the wired wall-control path is unchanged.
Verify: Genie's chart lists Chamberlain yellow Security+ 2.0, purple Security+, red/orange Security+, green Billion Code and selected DIP-switch branches. Confirm the active receiver/Learn-button generation before programming.
Wall-mount geometry changes the troubleshooting map
RJO101 mounts beside the torsion system instead of using a ceiling rail and trolley. That means travel, cable tension/door condition and compatible wall-mount parts must stay model-specific.
Do not reuse belt/chain trolley instructions from a ceiling-mounted Chamberlain opener simply because the myQ app looks the same.
Yellow Learn-button evidence is current-generation RJO evidence
Chamberlain's current RJO replacement-cover documentation identifies 2023-to-present wall-mount units with a yellow Learn button and explicitly lists RJO101 compatibility.
For remote replacement, exact opener + active receiver remains stronger than guessing from the exterior housing.
Common troubleshooting paths for this model
Route from the observed symptom or code. Do not use model identity by itself as proof of the failed part.
Remote/keypad replacement
Start from RJO101 and the current yellow-button compatibility path; check any added receiver separately.
Open the exact troubleshooting path →Power outage
Battery backup is part of this model; distinguish AC loss from a failed/charging battery state.
Door/cable condition
Wall-mount opener diagnosis must stop if door cables, springs or balance are abnormal.

Capture these facts before you order or escalate
A clean handoff preserves the evidence that separates opener identity, receiver compatibility and the actual failure symptom.
Motor-unit label
Photograph the full label showing RJO101 and any SKU suffix. Use that label for manuals and model-specific parts.
Active receiver / Learn control
Record the Learn-button color or external receiver model separately. A replaced receiver can change remote compatibility without changing the opener model.
Exact symptom or signal
Write down the code, blink count, sensor LED pair, direction of travel and where the door stops or reverses before changing settings.
Door-system boundary
If the door is crooked, off-track, unusually heavy, or has damaged spring/cable hardware, stop opener troubleshooting and hand off the mechanical door problem.
Model-specific guardrails
- RJO101 is not a ceiling-rail opener.
- Do not work on torsion springs or tensioned cables as part of opener troubleshooting.
- Use the exact RJO101 parts/manual family for locks, lights, battery and drive components.
Never use opener force or a safety-system bypass to compensate for a heavy, damaged, off-track or unbalanced garage door.
