Garage door jerks when opening?


If your garage door jerks when opening, it can be frustrating and concerning. This issue can be caused by various factors, including problems with the garage door opener, track misalignment, or worn-out rollers. In this article, we will dive deeper into the potential causes of a jerking garage door and explore possible solutions to resolve the issue.

Potential Causes of a Jerking Garage Door

1. Garage Door Opener Issues: One of the common causes of a jerking garage door is a problem with the garage door opener. If the opener is not functioning properly, it may struggle to smoothly open or close the door, resulting in jerking movements. Issues with the opener can include worn-out gears, motor malfunctions, or misaligned sensors.

2. Track Misalignment: Another possible cause of a jerking garage door is track misalignment. Over time, the tracks that guide the garage door can become bent or misaligned, causing the door to jerk when opening or closing. This misalignment can prevent the door from moving smoothly along the tracks, leading to jerky movements.

3. Worn-out Rollers: The rollers on which the garage door moves can also contribute to jerking movements. If the rollers are worn-out, damaged, or not properly lubricated, they can cause the door to jerk when opening or closing. Regular maintenance and lubrication of the rollers can help prevent this issue.

How to Resolve a Jerking Garage Door

1. Check and Maintain the Garage Door Opener: Start by inspecting the garage door opener for any visible issues. Look for worn-out gears, loose connections, or misaligned sensors. If you notice any problems, consult the manufacturer’s manual or contact a professional garage door technician for assistance. Regular maintenance, such as lubricating the opener’s moving parts, can also help prevent jerking movements.

2. Inspect and Adjust the Tracks: Examine the tracks to ensure they are properly aligned. If you notice any bends or misalignments, you may need to gently tap them back into place using a rubber mallet or seek professional help for track realignment. Regularly cleaning the tracks and removing any debris can also help prevent track misalignment.

3. Replace Worn-out Rollers: If the rollers are worn-out or damaged, they should be replaced. Consult the manufacturer’s instructions or seek professional assistance to ensure you choose the correct rollers for your specific garage door model. Additionally, regularly lubricating the rollers with a silicone-based lubricant can help prevent jerking movements and extend their lifespan.


A jerking garage door can be a frustrating issue, but it is often solvable. By addressing potential causes such as garage door opener issues, track misalignment, and worn-out rollers, you can resolve the problem and restore smooth operation to your garage door. Regular maintenance and periodic inspections can help prevent jerking movements and prolong the lifespan of your garage door system.
