How to Adjust a Garage Door Spring

Adjusting a garage door spring can be a dangerous task and should only be attempted by experienced individuals who are familiar with garage door systems. However, here are some general steps to adjust a garage door spring:

1. Gather the necessary tools: To adjust a garage door spring, you will need a ladder, a pair of pliers, a winding bar, and a socket wrench.

2. Determine the type of spring system: There are two types of garage door springs - torsion springs and extension springs. Torsion springs are located above the door opening and extension springs are located on either side of the door.

3. Identify the problem: Before adjusting the spring, you should identify the problem with the garage door. Is the door opening too quickly or too slowly? Is it difficult to open or close? Knowing the issue will help you determine how to adjust the spring.

4. Release the tension: If you have a torsion spring system, you will need to release the tension on the spring before making any adjustments. This can be done by using a winding bar to turn the spring until the tension is released. If you have an extension spring system, you will need to use pliers to pull the safety cable and release the tension.

5. Adjust the spring tension: Once the tension is released, you can adjust the spring tension using a socket wrench. Turning the wrench clockwise will increase tension, while turning it counterclockwise will decrease tension. Make small adjustments and test the door to ensure that it is operating properly.

6. Reapply tension: After making any adjustments, you will need to reapply tension to the spring. For torsion springs, use the winding bar to turn the spring in the opposite direction. For extension springs, use pliers to pull the safety cable and reapply tension.

7. Test the door: After adjusting the spring, test the door to ensure that it is operating smoothly and safely. If there are any issues, repeat the process until the door operates properly.

Remember, garage door spring adjustment can be dangerous, so if you are unsure about any part of the process, it is best to seek the help of a professional.
