Garage Door Roller Popped Out
A bent garage door section or a loose hinge can cause problems when opening or closing the door.
Garage door roller popped out. Loose hinges will make the door sag which can disrupt its motion and roll it out of position. Loose parts may also cause your garage door rollers to come off track so tighten any bolts and screws that appear loose. If you have a roll up door check the hinges that connect the panels together as well. Raise the door partially by lifting it until one set of rollers aligns with the problem area on the garage door track.
If you notice that the rollers have jumped the track immediately stop using the door until it can be repaired. The first thing to do when a garage door has a wheel or roller that is popping off the track is to make sure the problem actually originates from the rollers and not from the door itself. All the moving parts of a garage door need to be aligned for it to work properly.
