Garage Door Opener Problem, please help!!!
I have a Craftsman 1/2 hp garage door opener (Model: 139.53910D) that is just over a year old. The last two nights when I came home the opener had no power (the outlet it was plugged into had power) neither remote or the wall mount would work. But the followong two mornings the unit worked again, can someone give me an idea what is happening and advice. Thank you
