I don't have a clue.
Look on the back of the faceplate. There might be instructions there on how to reset the controller. If not check the manual. It's available online if you don't have one.
I think I'd reset it by removing back up battery and unpluging it for 5 minutes as well.
Make sure the faceplate it plugged in all the way.
Look for spider webs. Maybe they're shorting it out somehow. Far fetched but who knows.
Ill give it a shot, thanks for the tip.
