Why Is My Garage Door Not Closing? Troubleshooting Tips and Fixes

As a garage door opener specialist, I have come across various issues with garage doors, one of the most common of which is the garage door not closing. A garage door that won’t close can be frustrating and can pose a security risk. In this article, we’ll explore the reasons why your garage door may not be closing and what you can do to fix it.

Reasons Why a Garage Door Won’t Close

There are various reasons why a garage door won’t close. Below are some of the most common causes:

Sensor Obstruction

Garage doors are equipped with sensors that detect objects in their path and prevent the door from closing. If there is an obstruction in front of the sensor, the door will not close. Common objects that can obstruct the sensor include boxes, toys, or even a stray pet.

Misaligned Sensors

If the sensors are not aligned properly, the garage door may not close. The sensors need to be facing each other and their alignment should be checked regularly. Over time, the vibrations from the garage door can cause the sensors to become misaligned.

Sensor Malfunction

If the sensors are functioning properly but the garage door still won’t close, it could be a sign of a malfunctioning sensor. A malfunctioning sensor will need to be replaced.

Remote Control Issues

If the remote control is not working properly, the garage door may not close. Check the batteries in the remote and ensure that it is programmed correctly.

Broken Cables

If the cables that lift and lower the garage door are broken, the door may not close. Broken cables need to be replaced by a professional.

Damaged Rollers

If the rollers on the garage door are damaged, the door may not close. Damaged rollers can cause the door to become misaligned, making it difficult to close.

Track Obstruction

If there is an obstruction on the garage door track, the door may not close. Obstructions can be caused by debris or foreign objects in the track.

Before calling a professional, there are a few things you can try to fix a garage door that won’t close. Below are some troubleshooting tips:
