Garage Door Opener Trolley Stuck

My 10yr old house has a sectional aluminum door and a 1 2hp craftsman garage door opener.

Garage door opener trolley stuck.

The trolley is on garage door end not on the opener end. When i disconnected the door it seemed to open and close by hand smoothly. Poor lubrication is a very common and easy to fix explanation for why you might find your garage door stuck. My first problem was the door would close.

I disconnected the chain and pressed the wall switch to make sure the gear rotated clockwise so that it would be as if garage door was closed. The trolley moves along the chain drive the long track attached to the ceiling when the garage door is opening or closing attached via a metal. This can be a quick fix by identifying the object and then removing it. Loosen the chain or belt by adjusting the outer nut 4 to 5 turns.

Your jammed garage door can be caused by something as simple as an obstruction in the track. Check to see if the trolley has been disconnected. Recently it opened all the way until the trolley hit the bolt that stops it from going any further. Manually bring the door to the closed position.

Even with regular maintenance garage doors can sometimes stick refusing to open or close. I decided to unbolt the chain from the trolley to allow the opener to move again. Once it topped out the opener stuck there. Check to see if anything a shovel broom etc fell and is now stuck in the track that is causing it to be lodged.
