House built in the 80s has a genie opener. It’s stopped opening and I thought a switch would cure it. While installing the switch, the opener activated, up, down, whatever. Finish and switch won’t work. I take the switch off, wait a few minutes and touching the wires fires it up, open, close. Will do this two or theee times, then quit. On the last attempt, I can hear the genie growling, then stops. Wait. Few minutes, operates normally without the switch. Rinse and repeat.
Time for a new one? Is installing one an unbolt / bolt exercise?
