The B4613T is a 3/4 HP-class DC belt-drive Chamberlain opener with 1,000-lumen integrated LED lighting, battery backup, smartphone control, integrated Bluetooth, a yellow Learn button and Security+ 2.0.
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
No exact-model remote row is published locally yet
That does not mean the model is unsupported. Use the active receiver / Learn-button evidence and the manufacturer’s current compatibility row rather than inferring a remote from case shape, frequency or a nearby model.
Wall-control compatibility for this model
Wired controls follow the opener logic/control interface. Wireless wall consoles follow the active radio receiver.
Motion-Detecting Wall Control Panel
Wired logic path. Chamberlain's current 041A7327-1 compatibility list explicitly includes B4613T.
myQ Control Panel
A same-brand or myQ label does not make 889LM universal. Verify the opener generation and manufacture date before ordering.
Verify: Chamberlain Group documents the 888LM/889LM control-panel family for Chamberlain/LiftMaster Security+ openers manufactured after 1998 with purple or red/orange Learn buttons. Do not apply this to Security+ 2.0 yellow-button openers.
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.
The B4613T sits in the current yellow-button Chamberlain family
Chamberlain lists a yellow Learn button and Security+ 2.0 for the B4613T. That means older green, red/orange or purple-button programming instructions are the wrong starting point for this model unless you are programming a universal accessory that explicitly asks you to select a color family.
When replacing a remote or keypad, use the yellow-button generation as an identification clue and then verify the exact accessory against current Chamberlain compatibility data.
Battery backup is part of the model, not an optional assumption
Chamberlain specifies battery backup for the B4613T. During a normal AC outage, the opener's backup-power system is therefore a legitimate troubleshooting branch if the unit does not respond.
Do not jump directly to replacing a battery based only on one failed cycle. Follow the model's owner guide and status indications, and distinguish a battery condition from a mechanically stuck door or an opener that has lost normal AC power for another reason.
myQ setup uses both Wi-Fi and integrated Bluetooth
Chamberlain describes integrated Bluetooth as part of the setup path that reduces connection time to the myQ app. A pairing/setup complaint is therefore different from a physical door-closing fault.
If the door moves from the wall control but the app is offline, keep the troubleshooting focused on connectivity. If the door itself will not close and the safety sensor LEDs are abnormal, work the sensor branch first.
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.
Door only closes while holding the wall button
Treat this as a safety-system warning. Check the photo-eye path, LEDs and low-voltage sensor wiring rather than using the hold-to-close behavior as a permanent workaround.
Open the exact troubleshooting path →Opener lights flash and door will not close
On affected Chamberlain Group generations this often points back to the safety-reversing sensor system. Use the exact LED state and model behavior.
Open the exact troubleshooting path →Remote or keypad replacement
The B4613T is a yellow Learn button / Security+ 2.0 opener. Start with the current yellow-button compatibility branch rather than a legacy color procedure.
Open the exact troubleshooting path →B4613T went offline after router/Wi-Fi change
If the opener previously worked in myQ and still appears in the account, use Update Wi-Fi Settings before considering a factory reset.
Open the exact troubleshooting path →Door hits the floor and reverses
If the sensor system is normal and the door moves freely, the down-travel setting becomes a stronger diagnostic branch.

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 B4613T 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
- Chamberlain lists the B4613T with integrated 1,000-lumen LED lighting and battery backup.
- Yellow Learn button / Security+ 2.0 is the key radio-generation identifier for compatibility research.
- A 041-0136 safety-sensor kit is listed by Chamberlain as compatible with the B4613T, but always check the current parts page before ordering.
- Do not defeat the safety sensors or raise force to mask a door that is binding or mechanically unsafe.
Never use opener force or a safety-system bypass to compensate for a heavy, damaged, off-track or unbalanced garage door.
