Sensor Problem

I had to change the sensors for my 3 doors after a flood. Two of the doors worked fine. On the third door the Sending sensor lite up but the Receiver did not. I checked the wires and even tried installing the sensors direcly to the Raynor for testing. I even tried installing a spare receiver I had. The receiver blinked intermittently and sometimes not at all while the sender stayed on. I tried and retried the connections. Do you think the problem might be the logic board?
I'm still able to operate the door by keeping the button pressed until door is down. Thanks for the help

You need a new pair of photo cells.

You probably have a break in the wire inside the sheathing. I would run new wire before i bought a new logic board. After you run new wire your garage door opener should work fine. garage door
