Troubleshooting Common Issues With Your Garage Door

Garage doors are complex systems that can develop a variety of issues over time. While some problems require professional attention, others can be resolved with a bit of troubleshooting. This guide will help you understand and address some of the most common garage door issues.

1. Garage Door Won’t Open or Close

If your garage door isn’t opening or closing, it could be due to several reasons:

Remote Control or Wall Switch Issues: Check the batteries in your remote control. If the door doesn’t open even when using the wall switch, the problem could be with the power source or the motor.

Misaligned Sensors: Garage doors have safety sensors that prevent them from closing when something is in their path. If these sensors are misaligned, the door won’t close. Check the sensors and realign them if necessary.

Broken Springs or Cables: If the door opens only partially or not at all, the springs or cables may be broken. This is a job for professionals due to the high tension in these parts.

2. Garage Door is Noisy

A noisy garage door can be annoying and indicative of a problem:

Loose Hardware: Over time, the hardware of your garage door can loosen. Check all bolts and screws and tighten them if necessary.

Lack of Lubrication: Regularly lubricate all moving parts of the door, including the springs, hinges, and rollers, to reduce noise and ensure smooth operation.

Worn-Out Rollers or Hinges: If lubrication doesn’t solve the problem, the rollers or hinges may be worn out and need replacement.

3. Garage Door Opens or Closes Too Slowly

If your garage door is operating slower than usual, it could be due to:

Motor Issues: The motor could be failing or set to a slower speed. Check the owner’s manual for instructions on adjusting the speed.

Lack of Lubrication: As mentioned earlier, regular lubrication helps ensure smooth and efficient operation.

4. Garage Door is Off Its Tracks

A door that’s off its tracks can be dangerous and should be addressed immediately:

Obstructions in the Track: Check for any obstructions in the track that could be causing the door to derail.

Damaged Tracks: If the tracks are bent or damaged, they’ll need to be repaired or replaced.

Misaligned Tracks: The tracks need to be perfectly aligned for the door to operate correctly. If they’re misaligned, professional adjustment is necessary.

5. Garage Door Doesn’t Seal to the Bottom

If there’s a gap under your closed garage door, it could be due to:

Misaligned Sensors: As mentioned earlier, misaligned sensors can prevent the door from closing fully.

Worn-Out Seal: The seal at the bottom of the door can wear out over time and need replacement.


While this guide can help you troubleshoot common garage door issues, remember that garage doors are heavy and involve high-tension parts. Always prioritise safety and don’t hesitate to call a professional if you’re unsure about performing a repair. Regular maintenance can also help prevent many of these issues and keep your garage door operating smoothly.
