I replaced a faulty wall electrical plug in my kitchen. Electrical cords were falling off. I had to turn off the electrical circuit breakers on the rear house panel to put in a new plug. After replacing the plug my 1/2 h.p. GDO wouldn't work?? It doesn't respond to the mounted or remote controls. The lights on the push button don't work. The lights on the sensors don't work. I tried the reset button without success. The push pad outside lights up but didn't work. I plugged a lamp into the same electrical plug the GDO uses and it lights right up. So I know the GDO plug is working but won't repond to anything. Is there a fuse inside the housing?? Any other suggestions?? The GDO was working fine until I changed the electrical plug in the kitchen & turned the circuit breaker off & on. Thanks!
There isn't a fuse. You are going to need to remove the cover on the opener and find out where you are losing the power. Maybe a neighbor has a volt meter you could use. I would check the power cord and then the logic board. Makes no sense but I would check for burnt or missing traces on the printed circuit board especially around that small transformer.
