How to troubleshoot a Chamberlain Gate Opener that won't run?
If your Chamberlain Gate Opener isn't running, start by ensuring the power supply is properly plugged into a functioning outlet and that the circuit breaker is working correctly. Also, inspect the wiring connections at both the power supply terminals and the control board to ensure they are secure. To check the power supply, use a voltmeter to verify 24Vac at the COM and 24Vac terminals on the power supply. Also, check for 24Vac at the end of the two wires leading from the transformer to the control board.
What to do if Chamberlain Gate Opener remote control doesn't work?
If your Chamberlain Gate Opener isn't responding to the remote, first check the remote's battery. If the YELLOW LED on the control board blinks rapidly when you press the remote button, the battery is likely good. If the LED doesn't blink, replace the battery. If the LED blinks but the operator still doesn't respond, try reprogramming the remote control.
