If your Chamberlain Gate Opener isn't responding, try these steps: First, if using a remote, try another one or a push button. If a push button is in use, try another button or a remote. If there's no push button, use a jumper wire on terminal 8, touching it to terminal 5 or 7. Check the manual release switch is in the operate (up) position. Examine the LEDs on the circuit board. Disconnect any wires from illuminated input LEDs on terminals 4, 5, 7, or 10 until the LED turns off. If the stop input LED on terminal 9 isn't lit, inspect the stop input device and its connections. If there's no stop input device, ensure a secure jumper between terminals 8 and 9. Check the circuit breaker button and press it if tripped. Finally, ensure power to the circuit board on terminals 13 and 14.
