Craftsman 1/2 horsepower GDO
Thanx to Don you are the man!!After reading 10 or 15 threads I was able to fix my model 139.53535srt.
What I had were two problems that occurred at the same time.My sending sensor stopped working because of corrosion at the sensor plug and my garage door went up and jammed the motor.All the info I needed to fix my GDO was contained in the posts I read and it was all downhill once I figured out what GDO meant.Just remember 10x's flashing overhead white lights is sensor problem and 5x's flashing green led light is motor overload problem.It really feels like money in my pocket. Thanks again.
