Through time, springs on all garage doors slow down or lose tension. This can cause the garage door to break down and not work properly. The process of replacing these high tension springs is demanding and potentially harmful and is only suited for serious do-it-yourself individuals. There is a wide range of garage doors, each with its unique spring types and also replacement technique. For example, garage door(s) can operate with either tension springs or extension springs or both of them. Double garage doors mounted with overhead springs generally use torsion springs attached to a bracket located at the center of the garage door and are widely used to demonstrate the principles of replacing door springs. To follow is a break down of what you will need and how to fix a broken garage door spring. This is brought to you by Riverside Door Repair.
Here’s what you will need:
- New Springs
- Winding Bars
- Close your garage door(s) and unplug the power cable to the opener. If the door opener is connected to the building’s main electrical system, disconnect the garage’s circuit breaker or take off the opener’s fuse and then detach the opener from your garage door. Contemporary models have a neutral place where you can put the opener while replacing the door springs, old models require you to completely detach the opener.
- Ensure old springs and the replacement springs match. This can be achieved by measuring the diameter and length of the old spring and comparing with those of the new springs. Using a chalk or marker mark the exact location of spring cone.
- Uncoil the old door springs to free the pressure on the door bar. Slip a winding bar onto a winding cone hole. Make sure the winding bar is 18 inches or more and the correct diameter for the cone. Using a wrench loosen the spring’s setscrews and lower the winding bar. Slip a 2nd winding bar onto another winding cone hole while holding on the 1st bar. Free the 1st bar and lower the 2nd bar. Replicate until all the pressure is released and the spring is completely unwound.
- Remove all the bolts that attach the spring’s stationary end to the anchor. Unscrew the spring’s set screw from the cable reels at the edge of the garage’s door. Take off the reels and slide off the springs from the door bar.
- Slide on the replacement spring. Ensure the stationary side (the side with a bigger hole) goes in first. Re-assemble the cable reel and repeat step 1 – 5 for your other replacement spring. Fit the garage door bar onto the cable reel. Twist the door bar to tighten the door shaft.
- Fix the torsion spring’s stationary end to the middle of the door and fasten the bolts. Ensure the stationary cone flush with the bearing plate of the anchor.
- Wind the new torsion spring on the garage bar. Fit the winding bar and thrust it up. Fit the 2nd winding bar while holding the 1st bar and push it up. Repeat this till the torsion spring is fully wound and has reached the mark that you made at Step 1. Repeat Step 5 – 7 for your other spring. The task of door springs is time-consuming but by carefully following the above steps you can successfully replace your old door springs.
