When a spring breaks, the other spring needs to have tension taken off to replace the bad spring. Garage doors have either torsion-mounted springs or extension springs. Torsion springs are on a shaft directly above the door. These springs should be replaced and adjusted by a professional only. They are under pressure and one small mistake can result in serious injury.
Extension springs can be replaced by the homeowner. To replace extension springs, the homeowner needs to know how to remove garage door spring tension.
Things You'll Need
- Two pairs of vice grips
Raise the garage door up to its fully open position. Directly below the bottom rollers on each side, attach vise grips to the door track.
Position the ladder to one side of the door beside the horizontal track. Locate the spring cable that is tied to an S-hook toward the front of the track.
With one hand grab the cable to pull the spring slightly. With the other hand unhook the S-hook from the track. Gently release the cable and allow the spring to go back.
Position the ladder on the other side and remove the spring tension the same way.
Tips & Warnings
- With spring tension off, nothing is carrying the weight of the door. Do not attempt to close doors until spring tension has been put back on.
