Step By Step Guide on How To Repair Garage Door Springs and Cables

Repairing garage door springs requires a systematic approach to ensure a successful outcome. Follow these step-by-step instructions to repair your garage door springs:

Step 1: Secure the door to the track

Before you egin any garage door spring repair, it is essential to secure the door to prevent any accidents. Use locking pliers or a C-clamp to fasten the track slightly above one of the rollers. This will avoid the door from suddenly shooting up and causing injury while you work on the springs. Pull the cord and unplug the garage door opener for added safety.

It would help if you took a few precautions to ensure a safe garage door spring replacement. Always use proper winding bars instead of using screwdrivers or pliers. Professional winding bars can be purchased online for around $25. Position your ladder to the side to avoid direct contact with the spring ends. Keep the garage door opener unplugged and locked in the lowered position. Lastly, wear eye protection and leather gloves to protect yourself from harm.

Step 2: Loosen the unbroken spring

To begin the repair process, insert a winding bar into the bottom hole of the winding cone on the good spring. Keep the bar steady while you loosen the two setscrews. It is important to hold on firmly, as the spring will exert strong torque as the screws loosen. Take your time and ensure the spring is fully loosened before moving on to the next step.

Step 3: Use two winding bars

Using two winding bars for added stability and control is crucial when dealing with garage door springs. Place the second winding bar into the hole at the 9 o’clock position. Remove the bottom bar and gradually unwind the spring a quarter turn at a time, alternating the winding bars with each turn. This method ensures a controlled release of tension and minimizes the risk of accidents.

Step 4: Remove the nuts and bolts

After fully unwinding the intact spring, proceed to remove the nuts and bolts that secure the stationary spring cones to the center bracket. Use a wrench or pliers to unscrew the nuts and bolts and slide the springs toward the end brackets. Take caution while handling the springs, as they can still have residual tension even when unwound.

Step 5: Secure the torsion tube

To proceed with the repair:

1. Attach locking pliers or a C-clamp to the center bracket to secure the torsion tube. This will prevent unwanted movement or accidents during the repair process.
2. Loosen the left and right setscrews, lift cable drums, and disconnect the lift cables.
3. Ensure the torsion tube is securely locked before proceeding to the next step.

Step 6: Slide the torsion tube over

Begin on the left side of the door and shift the torsion tube to the right to access and remove the cable drum. Once the cable drum is removed, slide the old spring off the tube. Be cautious while handling the spring, as it can still have residual tension, which can cause injury if not handled properly.

Step 7: Calculate the wire diameter

Before installing the new spring, it is crucial to calculate the wire diameter to ensure a proper fit. Measure the length of 20 and then 40 coils using a tape measure, noting the measurements in decimal form. Divide each measurement by the number of coils (20 or 40) to find the wire diameter. If the results match, the measurement is correct. For example, the measurement is accurate if 4.5 inches divided by 20 equals 0.225 inches, and 9 inches divided by 40 equals 0.225 inches.

Step 8: Reassemble, then hang on the bearing bracket

Now that you have the correct wire diameter, it’s time to reassemble the garage door springs. Install the new torsion spring replacement onto the tube, ensuring the stationary cone faces the center bracket. Reconnect the cable drum to the garage door wire. Put the torsion bar back into the left-side bracket and make sure it’s firmly in place.

Step 9: Install a new center bearing

To complete the repair:

1. Connect the stationary cones to the bracket.
2. Push the torsion bar to the left, then place the center bearing onto it.
3. Install the right spring and press the bearing into the stationary cone.
4. Reinstall the drum accordingly.
5. Attach both fixed cones to the center bracket to ensure the garage door aligns and works correctly.

Step 10: Deal with rusted parts now

If you encounter any rusted parts during the repair process, it is essential to address them promptly. Attach the lift cable loop to the pin of the new bottom bracket. Insert the new roller, then replace the old bottom brackets and cables with the new ones. This will help your garage door work smoothly and last longer.

Step 11: Anchor the cable in the slot

To prevent the lift cables from slipping, thread them vertically between the rollers and the doorjamb. Once threaded, slide the lift cable and stop through the slot on the drum. This will anchor the cable securely in place, preventing accidental dislodging.

Step 12: Tighten the drums

To make sure the cables are correctly tensioned, tighten the drums. Secure locking pliers onto the torsion tube to hold it steady while tightening the drums. Turn the drum to wind the cable around the winding grooves. Pull the cable tightly before tightening the set screws. Repeat this process on the other side to achieve equal tension for balanced door operation.

Step 13: Tighten the garage door tension springs

Insert a winding bar into the cone and twist it towards the ceiling. Rotate the spring a quarter turn at a time, alternating between winding bars. Follow the spring supplier’s guidelines for the total number of turns. If no recommendation was provided, do 30 quarter turns for a 7-ft.-tall door and 36 quarter turns for an 8-ft.-tall door. Properly winding the tension springs is crucial for safely operating your garage door.

Step 14: Stretch the springs

Once the spring is fully wound, gently tap the winding bar to extend the spring from the center by about 1/4 inch before tightening the set screws. Rotate the set screws until they touch the torsion tube, then tighten them by half to three-quarters of a turn. Avoid over-tightening, as it could damage or deform the torsion tube. Proper tensioning of the springs is vital for your garage door’s smooth and balanced operation.

Step 15: Lubricate the spring with a garage door lubricant

Lubrication is essential to guarantee smooth operation and prolong the lifespan of the springs. Place cardboard or a paper grocery bag between the spring and the wall to shield it from overspray. Apply garage door lubricant generously to the spring, ensuring thorough saturation. Remove any extra lubricant with a cloth. This minimizes friction, ensuring the springs function smoothly and quietly.

Conclude by Testing the Tension of the Garage Door Spring.

Remove clamps and pliers from the torsion tube and track. Lift the door by hand about 3 ft. If it stays, the springs are properly adjusted. If it falls, add a quarter turn to each spring. Keep adjusting until the door stays in place. Reconnect the opener if it’s working; otherwise, learn how to open the door manually.
