Craftsman Garage Door Opener Repair!

First, verify that the trolley is against the stop bolt.

Release the door from the opener by pulling the Emergency Release Rope.

Manually bring the door to a closed position.

Unplug the opener, then loosen the chain by adjusting the outer nut 4 to 5 turns. Loosen stop bolt a few turns. This relieves the tension.

Run the motor unit from the remote control or door control. The trolley should travel towards the door and stop. If the trolley re-engages with the door, pull the Emergency Release Rope to disengage.

Re-tighten the outer nut, so the chain is 1/2 above the base of the rail.

If the trolley does not move away from the bolt, repeat the steps above.

If the trolly is not on the stop bolt and makes a loud humming noise and doesnt lift/ lower the door, the gear and sprocket assembly could be worn out. Call for service.
