If your LiftMaster garage door not closing properly, it can be frustrating and concerning. The garage door is an essential part of your home’s security and convenience, and a malfunctioning door can compromise both.

In this article, we will cover the common causes of LiftMaster garage doors not closing and provide you with solutions to fix the problem.

Reasons for LiftMaster Garage Door Not Closing

Here are some common reasons why your LiftMaster garage door may not be closing:

Misaligned Safety Sensors

The LiftMaster garage door opener is equipped with safety sensors located at the bottom of the garage door. These sensors are designed to detect any obstruction in the door’s path and prevent the door from closing. If the sensors are misaligned, the garage door may not close.

Dirty or Blocked Safety Sensors

If the safety sensors are dirty or blocked, they may not be able to detect any obstruction in the door’s path, and the garage door will not close. Dirt, dust, and spider webs can accumulate on the sensors and affect their performance.

Malfunctioning Garage Door Opener

If your LiftMaster garage door opener is malfunctioning, it may not be able to close the door properly. This can be due to several reasons, such as a faulty circuit board, a damaged motor, or worn-out gears.

Broken Torsion Springs

The torsion springs are located above the garage door and are responsible for lifting and lowering the door. If one or both of the springs are broken, the garage door will not close.

Obstruction in the Door’s Path

If there is any obstruction in the door’s path, such as a chair, a box, or a bicycle, the garage door will not close. The LiftMaster garage door opener is designed to detect any obstruction in the door’s path and prevent the door from closing to avoid accidents.

How to Fix a LiftMaster Garage Door That Won’t Close

Here are some solutions to fix your LiftMaster garage door that won’t close:

Check the Safety Sensors

Check the safety sensors located at the bottom of the garage door. Make sure they are aligned properly and facing each other. If they are not aligned, adjust them until the LED lights on both sensors are lit.

Reset the Garage Door Opener

Replace Broken Torsion Springs

If the torsion springs are broken, you will need to replace them. This is a job best left to professionals, as the springs are under high tension and can be dangerous to handle.

Make sure there are no obstructions in the door’s path, such as a chair, a box, or a bicycle. Move any obstructions out of the way and try closing the door again.
