Anyone having remote problems with Sears-Craftsman GDOs should check with Liftmasters. They make the remotes and electronic circuitry for Sears-Craftsman.

I had a second remote fail. After purchasing a new remote I messed with it for two days; following the written instructions to the letter and any other possible combination. I called Liftmaster and had the problem solved in less than 3 minutes, using a step stool, cordless phone and my index finger. EXTREMLY friendly and helpful.
Come to find out that the Sears recommended replacement remote was the incorrect model and part number. There are several circuit boards used in Sears-Craftsman GDO's, each circuit board has several variations. Liftmaster can get you the absolute correct remote model number and back into operation in no time.
The following place claims to carry Chamberlain/LiftMaster Garage Opener Parts. I found them using a search engine. I know nothing else about them and am not endorsing them.
