How To Do A Garage Door Roller Replacement?

Table of Contents

A garage door roller replacement is something many want to know how to do. In modern era garage doors, there are four or five sections that extend across the entire width of the garage door opening, which connects with hinges. On each hinge bracket, there is a mount for a roller that guides the garage door tracks on each side of the garage door. Both rollers help raise and lower the garage door along the guide tracks. Today, we will be looking at the steps to a garage door roller replacement for the garage door’s top and bottom.

Disclaimer: It is important to note that this article is for informational purposes only: a garage door roller replacement should only be done by professionals, like Garage Door Doctor, who has experience and expertise in the field.

Steps To Replacing A Top Roller

  1. With an electric door opener, if you have it, close the garage door. After pulling on the door’s release handle, click the garage door’s remote button to allow the garage to raise the opener’s carriage. Finally, disconnect the garage door opener’s electrical cord from the outlet immediately after the carriage has stopped moving.
  2. Next, you want to unfasten the bolt that helps secure the top roller mount to the door. This can be done with a socket set. Slide the retainer bracket, making sure to do it with the roller attached from the mount.
  3. After, insert a brand new roller into the bracket. You want to position the roller at an angle and then just slip the roller’s front edge into the track. This should be done before rotating the axle toward the garage door and aligning the bracket with the bolt that is on the mount.
  4. Finally, plug the opener back into its outlet. Press the button on the garage door’s remote to lower the carriage. Lower the garage door until it connects with the door’s carriage arm. Now that it is complete, it is best to test the new roller’s operation by raising and lowering the door!

Steps To Replacing A Bottom Roller

  1. First, you want to raise your garage door. Disconnect the opener’s power cord from the electrical outlet. In order to release the carriage, you want to pull the rope handle.
  2. Next, you want to place a C-Clamp on the track. The C-clamp is going into the track that is opposite to the side of the door where you want to replace the roller.
  3. After, you need to locate the intersection of the vertical, straight track, and the 90-degree elbow section of the track. This will be beneath the damaged roller. You want to bend the curved lip part of the straight track area that is beneath the intersection. This can occur with a pair of slip-joint pliers. Doing this will allow you to have a width that is enough to have the roller slip out of the track.
  4. Now, you want to roll the door down until the roller centers into the broadest part of the channel’s bend. You must use your hands to bring the garage door down.
  5. After, you want to place a screwdriver between the curved edge of the roller and the channel. Push the roller out of the track by prying on the screwdriver. You want to pull hard on the corner of the door inward until you see the roller clear the track.
  6. Furthermore, you will now slip the old roller out of its axle mount. Carefully slide the new roller into the mount. Push the door back into its position adjacent to the track. Cautiously, slide the roller back into the track. You want to slide the garage door upward so that the new roller is within an elbow portion of the track. It is vital to straighten the curved track section with a hammer to help return it to its original condition. If need be, repeat the process with the other bottom roller.
