A garage door that s out of alignment can be very dangerous.
A crooked or off balanced door.
Energy from the spring turns the drum which either winds or unwinds the cable thereby lifting or lowering the door.
One of the most likely culprits when you have a crooked garage door is a broken torsion spring.
Warping of the door will also cause it to run crooked and stick in the tracks.
Push the door back to adjust the door and get the center aligned again.
Garage doors have a cable on each side that s wound around a drum with one end attached to the door itself.
The door might be hard to open and close due to it binding.
Regular adjustment will prevent a crooked door.
If one of these cables is broken power from the spring can t get to the door and the door hangs crooked.
It is possible that the vertical track down the side has gone out of alignment and shifted due to a slightly loose lag screw.
It might be loose or it fell out of the groove.
Without proper adjustment however the unit may run along the tracks unevenly.
By pushing the door back into position you should have made the vertical track straighten.
Hassle would be an understatement for a crooked garage door.
