I decided to unbolt the chain from the trolley to allow the opener to move again.
Garage door trolley stuck closed.
Release the door from the garage door opener by pulling the emergency release handle.
When i disconnected the door it seemed to open and close by hand smoothly.
The trolley should travel towards the door and stop.
Your jammed garage door can be caused by something as simple as an obstruction in the track.
Once it topped out the opener stuck there.
Garage door is off the track in some circumstances it is possible for the rollers that move the garage door up and down to jump the track.
In order to fix this you ll want to make small changes to the close limit setting until the door opener knows to stop once the door has reached the floor.
This relieves the tension.
This can be a quick fix by identifying the object and then removing it.
If your garage door gets stuck when opening this may be why.
Loosen the chain or belt by adjusting the outer nut 4 to 5 turns.
Run the motor unit from the remote control or door control.
Check to see if anything a shovel broom etc fell and is now stuck in the track that is causing it to be lodged.
Lodged garage door track.
If the rollers are out of the track contact a clopay master or authorized dealer to professionally and safely get your door back on track.
Recently it opened all the way until the trolley hit the bolt that stops it from going any further.
My 10yr old house has a sectional aluminum door and a 1 2hp craftsman garage door opener.
