Many home owners consider replacing garage door rollers to be a Do It Yourself task, though not all of them have the time required to do so. Regardless of whether you lack the experience or the time, it is best to contact a professional to complete this task. It is important to keep your garage door operating at maximum capacity at all times. After all, your garage door is not just a convenience, it is also a protection and security measure.
Upper Roller Replacement
- Close the garage door and pull the release handle. Use the remote button raise the carriage of the opener and disconnect the electrical cord after the carriage has ceased moving.
- Use a socket wrench to loosen the top roller mount bolts and slide the roller and retainer bracket away from the mount. To release the roller angle its axle inward. Slide the axle away from the bracket.
- Place the new roller in the bracket. Angle it and slide the front end of the roller into the track. Turn the axle toward the door. Align the bracket with the mount bolt. Secure the bracket and roller onto the mount using a socket wrench to tighten the nut. Repeat with the second upper roller, if required.
- Reconnect the opener to its power source. Push the remote button connect the carriage with its arm as it lowers. Lower and raise the door a few times to ensure it is operating properly.
Lower Roller Replacement
- Lift the garage door to its raised position. Disconnect the opener from its power source. Release the carriage by pulling its handle.
- Put a clamp on the track on the opposite side of the garage door from where you are replacing the roller. Tighten the clamp onto the track approximately 12” under the top of the garage door opening.
- Find the junction of the straight, vertical track and the 90 degree elbow portion of the track right below the roller which is damaged. The curved lip of the straight track segment right below the junction must be bent with a set of slip joint pliers. Ensure that the width of the bend is enough to slide the roller out of its track.
- Manually roll the door down to center the roller at the widest segment of the channel’s bend.
- Sandwich a screwdriver in the middle of the roller and the channel. Use the screwdriver to pry the roller from its track. The roller should clear the track, if you pull the corner of the door inward.
- Slide the damaged roller out of the axle mount. Slip the new one in. Push the door back into place next to its track and slip the roller back in. Push the door up to put the new roller into the elbow section of the track. Use a hammer to straighten the bent track. Repeat for the second lower roller, if required.
- Reconnect the arm to the opener’s carriage and reconnect its power source. Test the operation a couple of times.
The garage door springs are affixed to the lower mounting bracket. Removing the nuts and/or the bracket is extremely dangerous as it could cause the garage door to fall.
