Blog Article

Replacing a broken garage door spring requires caution due to the high tension involved. If you’re unsure, it’s best to seek professional garage door repair services to avoid injury.

Step 1: Disconnect Power and Secure the Door
Turn off the power to the garage door opener and manually lock the door in place to prevent movement during the repair.

Step 2: Identify the Type of Spring
Determine if you have torsion or extension springs, as the repair process varies for each type. Torsion springs are mounted above the door, while extension springs run along the sides.

Step 3: Release Tension from the Old Spring
For torsion springs, use winding bars to slowly release tension while securing the shaft. For extension springs, detach the safety cables carefully.

Step 4: Remove the Broken Spring
Once the tension is released, unscrew the spring from the center bracket and slide it off the shaft. For extension springs, unhook them from the track and pulleys.

Step 5: Install the New Spring
Attach the new spring in the reverse order, ensuring proper alignment. For torsion springs, wind the new spring using winding bars and adjust tension evenly.

Step 6: Reconnect the Cables and Test Balance
Reconnect all safety cables and open the door manually to test balance. If the door stays in place when halfway open, the tension is correct.

Step 7: Restore Power and Test Operation
Reconnect the garage door opener and test full operation multiple times to ensure smooth performance.

Final Tip: Since garage door springs are under high tension, hiring a garage door repair professional ensures safety and correct installation.
