Hi

I have a 5 to 6 year old 1/2 hp Craftsman unit which is not working at all. The door closed fine, and then the next time I tried opening it, nothing happened.

When I push either the wall button or the wireless remotes, I hear two clicks from the unit, but nothing even tries to operate. Power is active and I tried unplugging, waiting and plugging in again. The light bulb (60 watt bulb - I tested it and it's good) does not come on - even when I walk through the sensors. Sensors are not blocked or bent. I unhooked the door from the trolley, and the door lifts evenly and smoothly - no obstructions. But now I can't reconnect the door to the trolley on the track. It seems that when it closed, the trolley traveled about 1 inch beyond where the door wants to reconnect to it. Is the motor jammed in the down position? I'm not familiar with these things and would appreciate any advice. Many thanks.

Bob
