Garage door randomly opening on it's own. I purchase this unit last year for Christmas and just had it installed. I download the app to monitor the door because my neighbor notified me several time that my door was opened. I am a single mother with a 3 year old and I purchased this devise for safety reasons. This is not safe. I cannot be home alone with a small child with my door just randomly opening. Please help me!

Me too. Just installed a 970c and it is opening randomly. Obviously not the model because I see many complaining about the same thing with different models. Anyone have a solution. Can all this technology be turned off. I’d rather have a secure house than the convenience of technology.

OK - this applies to both LIftMaster and Chamberlin.  I have a LiftMaster in a new house (manufactured 1/2018) with a motion sensing LM wall control, and a WiFi gateway. 

My garage door started opening and closing randomly about a month ago.  Did a little reading, and the LiftMaster wall control was causing it to happen for some folks and there was a recall out on a similar model.  Tech support agreed to replace it.  I disconnected it from the WiFi and the wall control and it still kept opening and closing at random. I watched it happen when I was standing there and it was really disturbing.  I began shutting off the garage circuit breaker at night to keep my stuff from being stolen.

Called LM again and the second Tech Support guy tried to tell me it might be a short in the wiring...shorts don't behave randomly BTW....hilarious attempt to avoid responsibility.  Anyway, they agreed to send me a new logic board for the opener.  The new logic board fixed the problem.  PHANTOM OPERATION is a cop out for a bad product that opens (and closes) randomly.

They are using components in their circuit board that fail and generally leave the door in the open position.  I read one thread from an Electrical Engineer that had the same problem and I think he said the cause was cheap capacitors failing. 

Anyway, once you go through the obvious steps they recommend, to avoid responsibility - DEMAND a remedy.  The logic board was easy to replace - in like 10 minutes.  I still have little confidence in their products long term.  If this ever happens again, I am switching to a Genie will not look back.
