How to Fix a Garage Door
Time Required: Under 2 hours
An out-of-balance garage door can close too quickly, creating a potential hazard for kids and pets and placing unnecessary strain on the door’s parts. This guide will teach you how to adjust an uneven garage door to keep it running safely and smoothly.
- Move the garage door up and down until you find a place where the door stays suspended when you let go.
- If that point is more than four-feet or less than three-feet above the ground, you will need to balance the door.
- Keep the door open, a few feet off the ground, as this takes the pressure off the door springs.
- Put a ladder under the door to make sure it won’t close accidentally while you’re working on it.
Safety: To avoid injury, make sure the spring is completely free of tension before removing.
- Once the spring is free of tension, remove from its track hanger.
- If the door was closing too quickly, move the spring to the next higher hole on the bracket.
- If it was opening too quickly, move it to the next lower hole.
- Adjust the springs on both sides of the door the same way.
- Retest the door balance, as you did in Step 1.
- Close the door and use a level to determine that it’s hitting the ground levelly on both sides.
- If it doesn't, adjust the spring tension on each side of the door until it does.
- To make fine adjustments, try adjusting the lifting cable instead of the spring.
- The cable is attached to the door and runs to an S-hook that attaches to the track support.
- With the door propped open, take the S-hook out of the support, and tighten or loosen the cable as needed.
