What to do if Chamberlain remote control will not activate the garage door?
If your Chamberlain remote control isn't activating the garage door, first verify that the lock feature is not activated on the door control. If the lock feature is off, try reprogramming the remote control. If the remote still doesn't work, check the diagnostic codes to ensure the garage door opener is functioning correctly.

Another potential reason is misaligned or obstructed safety sensors; realign both sensors to ensure the LEDs are steady and that nothing is blocking their path.

The door control wires could be shorted, or the door control itself might be faulty; inspect the wires, replacing or correcting them as necessary. The safety sensors could be misaligned or momentarily obstructed; realign them to ensure both LEDs are steady and not flickering, and ensure nothing obstructs the sensor's path.
