Another Garage Door Opener Problem
When it does fail, does it always fail when the door is going up, or not? This is important becuse the motor is normally working harder to open the door than to close the door. If it always fails going up, then maybe the internal protection against motor overload is reacting to something. Have you sprayed the door hinges and rollers with a silicon spray lubricant? Also, is the track clean/clear of any dirt?
