DIY Garage Door Troubleshooting Tips


Maintaining a functional garage door is essential for the safety and convenience of your home. At American Garage Doors and Gutters in Kalispell, Montana, we understand the importance of a smoothly operating garage door. Here are some practical DIY troubleshooting tips to help you keep your garage door in top shape.

1. Check the Sensors

One of the most common issues with garage doors is misaligned or obstructed sensors. These sensors, located near the bottom of the door tracks, ensure the door doesn’t close on objects or people.


  • Make sure there are no objects blocking the sensors.
  • Clean the sensor lenses with a soft cloth.
  • Ensure the sensors are properly aligned; you should see a steady light if they are aligned correctly.

2. Inspect the Tracks and Rollers

Tracks and rollers can become clogged with debris or rust over time, causing the door to operate inefficiently or get stuck.


  • Clear any debris from the tracks.
  • Use a level to check that the tracks are perfectly vertical along their vertical sections and horizontal on the overhead sections.
  • Lubricate the rollers and tracks with a high-quality silicone-based lubricant.

3. Tighten Loose Hardware

The hardware on your garage door, including bolts, hinges, and brackets, can loosen over time due to constant movement and vibration.


  • Inspect and tighten all bolts and brackets using a socket wrench.
  • Pay special attention to the brackets that hold the tracks to the walls and ceiling.

4. Test the Balance

An imbalanced garage door can strain the opener and lead to more significant issues.


  • Disconnect the garage door opener by pulling the release handle.
  • Manually lift the door halfway and let go; it should stay in place.
  • If the door moves, it might be imbalanced, and you may need to adjust the tension on the spring system. This adjustment is best left to professionals due to the high tension in the springs.

5. Check the Cables and Pulleys

Worn or frayed cables and pulleys can pose serious safety risks and affect the operation of your garage door.


  • Visually inspect the cables and pulleys for signs of wear and tear.
  • If you notice any damage, it’s crucial to contact a professional to replace these components, as they are under high tension and can be dangerous to handle.

6. Test the Auto-Reverse Feature

The auto-reverse feature is a critical safety mechanism that prevents the door from closing on objects or people.


  • Place an object, like a roll of paper towels, in the door’s path.
  • Close the door using the remote. The door should reverse upon contact with the object.
  • If it doesn’t, you may need to adjust the settings or clean the sensors.

7. Listen for Unusual Noises

Garage doors should operate relatively quietly. Unusual noises can indicate underlying issues.


  • Listen for grinding, scraping, or squeaking sounds.
  • Lubricate moving parts such as springs, rollers, and hinges to reduce noise.
  • Persistent noises may require professional inspection to diagnose and resolve the problem.
