What The Rollers Do

The rollers in your garage door allow the door to open and close smoothly. All the moving parts of a garage door need to be aligned for it to work properly. If you notice that the rollers have jumped the track, immediately stop using the door until it can be repaired. Continuing to use the door when the rollers are off track can cause serious damage to the tracks or even the door itself. If this happens, you will need to bring in a professional to realign the whole structure or replace bent door panels.

Ways it Can Break

Rollers can get off track for a number of reasons. It is important to find the cause of the problems before you try to fix the door so it doesn’t come off again. Here are some areas to troubleshoot:

  • Loose tracks: If the tracks themselves are loose or detached from the walls and floor, the whole structure could become misaligned, causing the rollers to get off track. Tighten any loose bolts before fixing anything else.
  • Dented tracks: A serious dent or bend in the track can allow the rollers to come off. This is an easy fix – slide a piece of wood inside the track to act as a guide, and use a rubber mallet or hammer to pound the track back into shape.
  • Tracks are out of alignment: Both sets of tracks should be parallel with each other and even with the ground. Use a level to check the alignment and adjust the brackets accordingly.
  • Grime or debris buildup: Be sure the tracks are clean and clear so the rollers can operate smoothly.

How To Fix It

It is relatively simple to fix a garage door that has derailed. After troubleshooting the tracks to find the problem, you can now get to work putting the rollers back on track.

  1. Detach the door from the automatic opener by pulling the overhead string to disengage the opener. Now you will be able to open the door manually.
  2. Open the door partially so that one of the detached rollers is in line with the trouble spot on the track.
  3. Secure vise-grips to the tracks under the door to keep it open while you work.
  4. Use pliers to pry open one side of the track so the opening is wide enough to slide the roller back in. Repeat for each of the rollers that have come off the track, sliding them back in.
  5. When all the rollers are back inside the track, you can close the opening in the track. A simple way to do this is to put a small piece of wood inside the opened track which will support the shape of the track. Hammer the bent track back into the correct shape against the wood until it has returned to proper alignment with the rest of the track. Now you can remove the wood and vise-grips, and your garage door should function properly.
  6. Open and close the door manually a few times, to test if the rollers are operating smoothly. If you notice any more problems with jumping the track or misalignment, repeat the steps above until the whole track is in proper alignment.
  7. Reattach the automatic garage door opener. Your door should be good as new!
