Why Garage Door Not Closing

When your garage door won't close, it can be a frustrating and inconvenient problem. There are a number of potential causes for this issue, ranging from simple mechanical problems to more complex electrical issues. In this article, we will explore some of the most common reasons why a garage door may not be closing and provide tips on how to troubleshoot and fix the problem.

1. Obstructions in the Door's Path

One of the most common reasons for a garage door not closing is an obstruction in the door's path. This could be anything from a misplaced object to a misaligned track. To check for obstructions, first open the garage door all the way. Then, visually inspect the entire path of the door, looking for anything that could be blocking its movement. If you find any obstructions, move them out of the way and try closing the door again.

2. Misaligned Tracks

If the tracks that guide the garage door are misaligned, it can cause the door to bind and not close properly. To check for misaligned tracks, open the garage door about halfway. Then, look at the tracks from the inside of the garage. If the tracks are not parallel to each other, or if they are bowed or bent, they will need to be realigned.

3. Worn or Damaged Rollers

The rollers that help the garage door move along the tracks can become worn or damaged over time. This can cause the door to move unevenly or to bind, which can prevent it from closing properly. To check for worn or damaged rollers, open the garage door about halfway and then look at the rollers on the bottom of the door. If the rollers are cracked, chipped, or missing, they will need to be replaced.

4. Faulty Sensors

Garage doors are equipped with sensors that detect when something is in the way of the door. If these sensors are faulty, they can prevent the door from closing even if there is no obstruction. To check for faulty sensors, open the garage door about halfway and then place a piece of cardboard or wood in the path of the door. The door should stop moving when it hits the object.

5. Malfunctioning Motor

The motor is responsible for opening and closing the garage door. If the motor is malfunctioning, it can prevent the door from closing properly. To check for a malfunctioning motor, listen for any unusual noises when you try to open or close the door. If you hear grinding, squealing, or humming noises, the motor may need to be replaced.

6. Broken Springs

The springs on a garage door help to lift and lower the door. If the springs are broken, the door will not be able to close properly. To check for broken springs, open the garage door about halfway and then release it. If the door falls back down quickly, the springs are probably broken.
