Step 1: Install Safety Locks

Start by opening the sliding door of the garage. Fasten a C-clamp as tightly as possible on the steel door frame, right underneath the lower side of the door towards the slider. Repeat the process on the opposite side.

This is a precautionary means of keeping the door from dropping accidentally and should be taken while you are fixing the door.

Step 2: Investigate Metal rails

The garage door is supported by metal rails on both sides of the aperture. These tracks transition the door vertically to horizontally, with a sharp 90º curve at the midway mark.

Examine the vertical section of the garage door metal rails when the door is open. Run your fingertips down the sides of the tracks with a flashlight. Look for creases, dents, and other signs of wear and tear.

Take out the clamps and shut the door. Check the horizontal parts of the rails towards the ceilings for the same sort of damage when sitting on a ladder.

Step 3: Fix or Reinstall Detachable Bracket

The detachable mounting brackets secure the garage door rails that may be loose or damaged. It is usual for these brackets to weaken over time. It would help if you tightened the brackets securely into the door frame using the screwdriver set. Damaged brackets can occasionally be forced back into form manually or with a claw bar. If not, you can replace them with brackets relevant to your garage door’s model.

Step 4: Secure the Door

Secure the Door

Start by opening the garage door. Remove the garage door opener from the wall. Place a ladder against the open door to hold it so you can work safely. Then slide the safety release rope attached. Lift the door on top of the leaderboard and secure it using C-clamps.

Step 5: Take out the Extension Rod

Using the screwdriver to tighten the pinion and slip out the bolt. Allow the safety cable to hang down and then remove it. Remove the extension rod while it is still loose from the safety cable.

Step 6: Buy and Install an Extension Spring

Extension springs are color-coded according to stress or power level. The color of the new extension spring must be the same as the previous one. Your garage door includes two springs, and it’s generally a good idea to repair it at the same time, even if just one side is broken. This will reduce strain on both ends. After you have bought the springs, you must insert the safety cable through the new extension spring. Pass the nut through the pulley cable so that the pulley may be reattached to the other side of the spring.

Step 7: Secure the Door

Lift the garage door to disconnect the door opener and secure the C-clamps. The extension and springs are no longer strained and have been set safely, so it doesn’t bother you or fall.

Step 8: Disconnect the Pulley Cable

Detect the position of the S-hook on the door and mark it using tape, then unhook it. After you have unhooked the door hook, take the wire loop off the door’s base frame.

After which, you can unscrew and detach the nut to disconnect the pulley from the spring. After the pulley cable has been removed, you can discard it.

Step 9: Change the Rollers, Lift Cables, and Bottom Brackets.

After securing your door and removing the pulley cable, now is the ideal opportunity to replace any rusty rollers, lines, or bottom brackets. To achieve this, first, attach the lift cable loop to the new bottom bracket.

Step 10: Tighten the drums.

Cable drums are a vital part of any garage door that opens with a cable system.  Drums are attached to the gear system and serve as a pulley to raise the door. After you’ve replaced the defective pieces, use a locking clamp to secure the torsion pipe while tightening the drums.  Before locking the setscrews, pull the cable tightly to equalize the strain on both sides. If not, the door will keep opening unevenly.
