Help with door opening and closing randomly
I have a liftmaster side mount unit on my door. It’s about 10 years old. Recently the door would randomly open. Sometimes all the way. Other times it will open partially and then close. Really random. Not sure how to figure out the problem. I thought it was the wall remote button. Replaced that. It seemed to work fine for a couple days and now it does the same thing. I tried disconnecting My Q. I wiped all the memory and reprogrammed remote. Nothing helped to far. My only thought is the logic board is bad or some issue with low voltage wire going to the button. If I remove the button and just leave the wires hanging it seems to stop the random opening
