Hello all, I have a Genie Intellicode model IS 550. This morning when working in the garage, I had to unplug/plug the opener and may have damaged the red LED receiver. How can you tell if it's damaged? Right now the opener cannot be operated from the wall controller. The red LED does not light up. I checked the DC voltage of the LED receiver and transmitter and see nothing. I saw some power at the terminals of the wall controller as well as the connections at the opener. When I used the remote controller, it turned on the light bulb of the opener.
Thank you in advance.
