Garage Door Jerks When Closing

If your garage door jerks or shakes when closing, it can be a sign of a problem. There are several possible causes, including:

Worn or broken springs - The springs are what lift and lower the door, so if they're worn or broken, the door won't be able to move smoothly.
Loose or damaged cables - The cables help to guide the door as it moves up and down. If they're loose or damaged, the door can jerk or shake.
Misaligned tracks - The tracks are what the door rolls on as it opens and closes. If they're misaligned, the door can bind and jerk.
Damaged rollers - The rollers help to reduce friction between the door and the tracks. If they're damaged, the door can jerk or shake.
Faulty motor - The motor is what powers the door to open and close. If it's faulty, the door may not be able to move smoothly.

If you're experiencing any of these problems, it's important to have your garage door inspected by a qualified technician. They can diagnose the problem and recommend the best course of action. In some cases, simply adjusting the door or replacing a few parts may be enough to fix the problem. However, if the problem is more serious, you may need to replace the entire door.
