Uneven Doors One of the easiest and cheapest garage door problems to troubleshoot is uneven doors that don’t go up or down properly. This is generally caused by something blocking the track and can be a simple matter of removing all debris from the way. A Broken Spring If your door isn’t raising or lowering as it should, it could be due to a broken spring. Whenever you lift the garage door, the springs and cables do the majority of the work to raise the door. It’s a good idea to check this regularly and replace the springs as soon as possible. The Door Opens But Won’t Close If you have a garage door opener, this is an obvious problem that should be repaired as soon as possible. Clean the lenses of the sensors, and make sure there isn’t anything in front of them. The Photo Eye Sensors Are Dirty or Misaligned This problem is often related to the photo eyes and can be repaired by cleaning them off and re-aligning them. The photo eyes are essentially beams of light that allow your opener to detect when the door is closed or opened, and it’s critical to have them clean and aligned correctly. The Up Limit Switch Needs Moving: This is a more complex issue and could be due to the up limit switch not being near enough to the motor unit, or the track not being straight. If it’s too far away, it’ll close before the garage door opens, and you won’t be able to use the garage door.
