Craftsman Garage Door Opener Problem

crt1May 11, 2012

Craftsman model 53985 1/2 hp loses power to the infrared sending unit when the door is opened. Then door will not close from remote. Power is restored to the unit when the door is closing and about 6 inches from fully closed. I have tried re aiming the sensors but that doesn't fix problem. Opener worked fine for about a year.

Sounds like a loose connection but this may help.

If when closing the door it reverses to the open position and the main light flashes 10 times it is a door sensor problem. Make sure the small light on each sensor is on and not flickering ever so slightly. (check closely) Tweak them a little even though they may seem to be okay. Check for 5vdc between terminals 2 and 3 on the rear of the motor unit. If there is no voltage or if it is greater than 6vdc the logic board is bad.
