Clutch? need more info.. wall mount or overhead? If it's wall mounted it could be the clutch, I don't think overheads have a clutch though. The first thing I'd do is get on a ladder and see if the chain is still attached to the sprocket... good luck

Garage door motor turns on makes noise chain does not move

I bet the Worm Gear is broken. Disconnect the power, remove screws on motor enclosure, remove housing, look for broken plastic gear pieces.
You can buy a replacement gear kit from sears (call them first, with your model number, to make sure).
It'll take you about a half hour to fix it.

My opener is a 1/2 horse lift master professional chain drive . The door will not close unless you hold the closer button in. From the remote it will only move a few inches and then reverse. The door works...

If the main light flashes 10 times when the door reverses it is a door sensor problem. If not, you probably have a bad RPM sensor board which is a small printed circuit board just in front of the motor.

I have a Sears Craftsman 1/2 horse garage door opener. When I push the button, I can hear it hum, but the chain won't move and it seems the sprocket is frozen?

If your door is stuck in the open position you will find the trolley is jammed against a bolt just in front of the motor unit. Remove that bolt and run the opener until the door closes. Now locate the 'up limit' control on the side of the motor unit and turn it 2 times in the opposite direction of the arrow printed on the cover. Replace the bolt.

My garage door opener moves about 8" then reverses direction before touching the limits

Remove the cover and take a look at the drive gear. It is white nylon and is just in front of the motor. It is most likely stripped. You can purchase a new one at Sears or any good door opener company. It comes with instructions.

Craftsman opener motor works, but chain does not move.

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.

How is the chain supposed to be aligned

sync the motor. the gear kit tells you how. get motor up and position trolley near motor, assuming you left chain/cable attached to trolley). Get motor up by running motor and then pushing button again. if motor reverse, let it run and it will stop in up position.

Motor sounds like it is running but sprocket doesnt move

how old is unit. sounds like gears are shot, takes $25 of parts and 2-3 hours to fix if you are handy. Take cover off, If it has white powder (Not ****), gears are shot.
