Re: Craftsman opener motor works, but chain does not...
If the motor is working but the chain does not move you must remove the cover on the motor and check to see that the chain is on the sprocket. If the chain is on the sprocket and the sprocket is not moving but the motor shaft is moving then the sprocket must be retightened onto the motor shaft.
The door will open manually, so I beleive the springs are not broken, but I will double check. The sprocket situation sounds like a more likely possibility. I will check on that when I return home from work. Thank both of you for the possibilities.
The horizontal ring gear has lost all of its teeth. They were apparently ground off when door stopped opening.
look at the springs above your door from the inside when its closed....they may be broken
