Why is my Chamberlain Garage Door Opener beeping?
Your Chamberlain garage door opener may be beeping because it has been activated through a device or feature such as Timer-to-Close.
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.

A communication error to the travel module may also be the cause; check the travel module connections and replace the module if necessary. 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.
