If the wires appear to be connected properly, here is a simple way to test for a shorted wire:
- Disconnect the sensors from the brackets.
- Detach the wires from the wire nuts or snip them approximately 12" from the sensors.
- Strip the wires on both ends and twist the matching colored wires together on each sensor to the motor of the garage door opener.
- Unfasten the wires from the operator terminals and reconnect them according to color to the matching terminals.
- Direct the sensors at each other - if the LEDs on both sensors light up, there is a problem with the wiring. Replace the wires.
- If the LEDs DO NOT light up, replace the sensors.
- If the LEDs still do not light up after replacing the wires or sensors, replace the logic board.
