Garage Door Opener Hits Stop Bolt

When my craftsman garage door opens up it goes all the way up until the trolley hit the safety pin.

Garage door opener hits stop bolt.

My 10yr old house has a sectional aluminum door and a 1 2hp craftsman garage door opener. To remove the trolley from the stop bolt follow the steps below. I decided to unbolt the chain from the trolley to allow the opener to move again. Trolley on garage door opener hits stop bolt and clicks 10 times.

A problem came along after the assembly was complete and i tested the garage door opener. 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. The proper fully closed position is when the seal on the bottom of the garage door is resting on the floor. Once it topped out the opener stuck there.

Tried to reset opening travel distance but it keeps traveling to the stop bolt and clicking. When i pushed the button the door began to open but it didn t stop and hit the stop bolt causing a lot of stress on the chain. Recently it opened all the way until the trolley hit the bolt that stops it from going any further. Simply lay a 2 by 4 on the ground and let the garage door come down on top of it.

However if your garage door doesn t bounce back up then you know you have a problem. It is a craftsman 3 4hp model 139 53918d. If your garage door hits it bounces up and starts to open again your garage door is working well. Manually bring the door to the closed position.

The trolly was parked where the door would normally remain closed. Was programed and working fine before today. When i disconnected the door it seemed to open and close by hand smoothly. Release the door from the garage door opener by pulling the emergency release handle.

Lastly you ll want to perform a safety test. First visually verify that the trolley is against the stop bolt. The garage door opener trolley should stop in the fully open position at minimum 1 inch from the stop bolt on the opener rail. Do you know what i need to do to limit the movement of the door model 139 53650srt craftsman thanks.

When the garage door opens about halfway or 5 feet from the ground and stops the up limit switch needs to be adjusted. Make sure the garage doorway is clear of persons or obstructions. If your garage door is closing fully and then reversing to open again then it may be due to a problem with the close limit switch.
