Garage Door Trolley Stuck On Stop Bolt

Thank you for your question on the door trolley jammed against the front stop bolt.

Garage door trolley stuck on stop bolt. Don is correct in that you may have a stripped drive gear but you will need to remove the motor cover to see if that is the problem. First visually verify that the trolley is against the stop bolt make sure the garage doorway is clear of persons or obstructions release the door from the garage door opener by pulling the emergency release handle manually bring the door to the closed position loosen the chain or belt by adjusting the outer nut 4 to 5 turns. Trolley on garage door opener hits stop bolt and clicks 10 times. Here are my steps to realign this module this applies to most craftsman garage door opener models.

Unplug the garage opener. It is a craftsman 3 4hp model 139 53918d. Ensure that chain isn t torqued against the bolt as this could be very dangerous to work on. I have compared with the other garage door opener i have and it stops on the way up 1 2 inch before the trolley hits the safety screw bolt.

When my craftsman garage door opens up it goes all the way up until the trolley hit the safety pin. Get shopping advice from experts friends and the community. You will need to pull the red emergency handle to release the door from the trolley. Was programed and working fine before today.

Tried to reset opening travel distance but it keeps traveling to the stop bolt and clicking. The image below will show you the front stop bolt. In a typical situation the motor for your garage door opener should stop running once the door has closed. If you find that it keeps running this can present a problem in your system.
