Default Garage door opener

This opener is about 15 years old. The number on the printed circuit
board is 14PC366B. Will have to get out the ladder again to get the
Craftsman model number. I'll get back with you.

Need a schematic for the printed circuit board in my Craftsman garage
door opener. Did lots of Googling. Found nothing. Learned that The
Chamberlain
Group makes the openers for Sears. Contacted them and asked for a
schematic. They said the board is proprietary, and they won't even
sell parts for it. Only complete boards for sale.



Quite often the problem is dirty contacts on the relay. Cleaning them with
light emery paper usually has worked for me...
