Have you tried the manufacturers site at either craftsman or sears. You should be able to find it there. You will need your model #.

IF THE DOOR MOVES 6-8 INCHES THE PROBLEM IS THE RPM SENSOR IF IT DOESN'T MOVE AT ALL THE CIRCUIT BOARD IS TOAST.
GET A SURGE PROTECTOR FOR THE OPENER - THIS SHOULD SAVE THE BOARD THE NEXT TIME.
HOPE THIS HELPS

It sounds like the logic board has quit working on the one opener. If you have had lightning or power surges you might remove the logic board and check for loose, burnt or missing traces on the printed circuit.

Remotes quit working on Craftsman 53975 garage


It sounds like you have a logic board problem. If your remotes work at all it is not a programming problem. You could pull the logic board and check for loose connections especially around the small transformer. 18 years for an opener is very lucky. Their average life is about 1/2 that.

Lights on overhead unit on garage door opener will not go off


This is not too uncommon. What tripped the breaker in your house also got to one of the relays on the logic board of your opener. The only cure I know of is a new logic board.

If the lights in the door sensors do not light you have either a bad logic board or bad wiring to the sensors. Replacing the logic board is usually the cure.
