Introduction

Garage door malfunctions can be a major source of frustration and inconvenience. They can also create a sense of insecurity if you’re unable to lock and secure your home properly. One of the most common issues faced by homeowners is a garage door that won’t open. But what causes this problem, and how can it be fixed? In this article we’ll look at the common causes and potential solutions, as well as some tips on how to prevent the issue in the future.

What Causes Garage Doors to Not Open?

Misaligned Sensors

One of the most common causes of a malfunctioning garage door is misaligned sensors. The sensors are usually located on the sides of the door and they act as a safety feature, preventing the door from closing if something is in the way. When these sensors become misaligned, the door will not open.

Broken Springs

Garage doors are counterbalanced with a tensioned spring system. If either the torsion springs or extension springs become damaged, the door won’t open. It’s important to note that these springs should only be replaced by a trained and experienced professional, as they are under immense pressure when working correctly.

Faulty Openers

The opener is the motorized device that controls the movement of the garage door. If the opener is not working correctly, the door will not open. This could be due to a malfunctioning power source, a worn-out motor, or a broken gear.

Broken Cables

The cables that run along the sides of the door are responsible for lifting the weight of the door. If one of these cables snaps, the door will not open. This is usually caused by a combination of wear and tear and incorrect tensioning.

Worn Out Rollers

The rollers are responsible for the smooth opening and closing of the door. If these rollers become worn out, the door will not open. This can be caused by a lack of lubrication or a build-up of dirt and debris.

Blocked Tracks

The tracks along which the door slides need to be free of any obstruction for the door to open correctly. If the tracks become blocked, the door will not open. This is usually caused by a build-up of dirt and debris.

What Are the Solutions?

Aligning Sensors

To fix misaligned sensors, you’ll need to check the alignment of the sensors and make any necessary adjustments. Make sure to check the alignment of both sensors, as the door will not open if one of the sensors is misaligned.

Replacing Springs

If the springs are broken, they will need to be replaced. This should only be done by a trained and experienced professional as the springs are under immense tension.

Repairing Openers

If the opener is not working correctly, you’ll need to check the power source, motor, and gears to identify the issue. This can usually be done with a basic multimeter. If necessary, the opener can then be repaired or replaced.

Replacing Cables

If the cables are broken, they will need to be replaced. This should only be done by a trained and experienced professional as the cables are under immense tension.

Replacing Rollers

If the rollers are worn out, they will need to be replaced. This can usually be done with basic tools. Make sure to lubricate the new rollers to ensure they don’t become worn out again.

Unblocking Tracks

If the tracks are blocked, you’ll need to remove any obstruction. This can usually be done with a vacuum cleaner and a brush. Make sure to clean the tracks thoroughly before attempting to open the door.

Conclusion

Garage door malfunctions can be frustrating and inconvenient, and one of the most common issues is a door that won’t open. The most common causes are misaligned sensors, broken springs, faulty openers, broken cables, worn out rollers, and blocked tracks. Fortunately, these issues can usually be fixed with some basic maintenance and repairs.
