5 Tips for Troubleshooting Your Garage Door When It Won't Close Completely

Garage doors are an essential part of your daily life, providing security and convenience for your home. However, when they malfunction and won't close completely, it can be frustrating and even dangerous. In this blog, we will discuss five tips for troubleshooting a garage door when it won't close completely.

Check the sensors

The first thing to check when your garage door won't close completely is the sensors. These sensors are located near the bottom of the door and are responsible for detecting any obstructions in the path of the closing door. If they are not aligned properly or if there is something blocking their signal, the door will not close all the way. Make sure that nothing is blocking the sensors and that they are properly aligned.

Inspect the tracks

Another common reason for a garage door not closing completely is an issue with the tracks. Over time, these tracks can become misaligned or damaged, preventing smooth movement of the door. Inspect them for any dents or bends that may be causing issues with the door's movement. You can use a rubber mallet to gently tap out any dents or call a professional to realign or replace damaged tracks.

Lubricate moving parts

If your garage door is making strange noises or struggling to close all the way, it may be due to a lack of lubrication on its moving parts. The rollers, hinges, and springs all need proper lubrication to function smoothly. Use a silicone-based lubricant on these parts and avoid using oil-based products, as they can attract dirt and grime.

Check the weather stripping

Weather stripping along the bottom of your garage door helps keep drafts, debris, and water from entering your garage. However, if it is damaged or worn out, it can cause the door to malfunction. Check the weather stripping for any tears or gaps and replace it if necessary. This simple fix can help your garage door close completely and improve the door's energy efficiency.

Test the limit switch

The limit switch is a safety feature that prevents your garage door from closing too far and potentially causing damage or injury. If this switch is not set correctly, your garage door can stop before fully closing. To test the limit switch, locate the adjustment screws on the motor unit and adjust them until the door closes completely. If you are unsure how to do this, it's best to call a professional for assistance.
