Garage door opener shakes when closing.
What should you do if there is damage to the garage door.
There are two types of pulleys.
When the door is opening or closing it runs on a set of tracks which keep the door in place.
Press fit pulleys and cast iron pulleys.
Cast iron pulleys are the less popular pulley type that consist of one solid cast iron piece.
The first thing you should do is close the garage door and inspect the spring s.
They should be inspected to ensure that they are aligned correctly on the wall.
If your press fit pulley system has surrendered you may be able to see frayed cables or a separated press fit casing.
In a torsion spring system the spring will be mounted on a spring bar torsion tube that is mounted to the header above the garage door opening.
This issue tends to be worse when the door has been closed for a while.
Here s how to easily fix a garage door that jerks when opening.
If your garage overhead is getting jammed or shaking and jerking as it closes the tracks should be checked.
