Garage Door Stops When Opening

Do you know what to do when your garage door stops when opening? It can be frustrating and inconvenient, especially when you’re in a rush or carrying heavy items. But fear not, because in this article, we’ll delve into the possible reasons why your garage door may be stop as it’s opening and what you can do to fix it.

There are several potential causes for your garage door to stop when opening. One common culprit is a malfunctioning sensor or safety feature. Garage doors are equipped with sensors that detect any obstructions or objects in the door’s path. If something is in the way, the sensor will trigger the door to stop in order to prevent any damage or accidents. It’s possible that the sensor may be misaligned or dirty, causing it to falsely detect an obstruction.

Another possible reason for your garage door stopping mid-opening is an issue with the door’s tracks or rollers. Over time, these components can become worn out, misaligned, or rusted, preventing the smooth movement of the door. As a result, the door may get stuck or come to a halt while opening. In some cases, the garage door opener itself may be the problem. If it’s old or its motor is worn out, it may not have enough power to fully open the door, causing it to stop prematurely.

Common Causes of a Garage Door Stopping When Opening

1. Faulty Garage Door Opener

The garage door opener is a crucial component of your garage door system, and if it’s not functioning properly, it can cause the door to stop suddenly. There are several potential issues with the garage door opener that can lead to this problem.

Motor Malfunction

A motor malfunction is one possible cause of a faulty garage door opener. This can happen due to wear and tear over time or as a result of incorrect installation. If the motor is not running at full capacity, it may struggle to lift the door, causing it to stop in the process.

Worn Out Gears or Sprockets

Another possible cause of a faulty garage door opener is worn out gears or sprockets. These components are responsible for transferring power from the motor to the door’s moving parts. If they become worn or damaged, they may not be able to effectively lift the door, resulting in it stopping when opening.

Electrical Problems

Electrical problems, such as a faulty wiring connection or a blown fuse, can also cause a garage door opener to malfunction. If there is an issue with the electrical supply to the opener, it may not be able to generate enough power to open the door fully, causing it to stop.

2. Obstruction on the Garage Door Tracks

Another common cause of a garage door stopping when opening is an obstruction on the tracks. The tracks guide the door as it opens and closes, and any obstruction can disrupt the smooth movement of the door.

Foreign Objects

Sometimes, small objects or debris can become lodged in the tracks, preventing the door from opening fully. This can be anything from dirt and leaves to small tools or toys. It’s important to regularly inspect and clean the tracks to ensure they are free from any obstructions.

Misaligned Tracks

Misaligned tracks can also lead to a garage door stopping when opening. If the tracks are not properly aligned, it can cause the door to get stuck. This can happen due to loose bolts or brackets or as a result of the tracks being bumped out of place.

Accumulated Dirt or Rust

Over time, dirt and rust can accumulate on the tracks, making it difficult for the door to move smoothly. This can cause the door to become stuck or stop when opening. Regular cleaning and maintenance of the tracks can help prevent this issue.

3. Broken Torsion Springs

Torsion springs are essential for counterbalancing the weight of the garage door, allowing it to open and close smoothly. If one or both of the torsion springs break, it can cause the door to stop when opening.

Symptoms of Broken Torsion Springs

There are several signs that indicate a broken torsion spring. These include the door appearing unbalanced, sagging at one side, or making loud noises when opening or closing. If you suspect a broken torsion spring, it’s important to refrain from attempting to fix it yourself as it can be dangerous. Instead, seek professional help for repair or replacement.

4. Misaligned Photo Eye Sensors

Most modern garage door systems are equipped with photo eye sensors that detect objects or people in the path of the door. These sensors are an essential safety feature, but if they become misaligned, they can cause the door to stop when opening.

Effect of Misaligned Sensors

When the photo eye sensors are misaligned, they may not detect an object or person in the path of the door correctly. This can cause the sensors to send a signal to the opener to stop the door from moving, even if there is no actual obstruction. This is a safety feature designed to prevent accidents or damage.

How to Realign Photo Eye Sensors

To realign the photo eye sensors, start by cleaning the lenses to ensure there is no dirt or residue interfering with their function. Next, check the alignment of the sensors and make any necessary adjustments. It’s important to consult the manufacturer’s instructions or seek professional assistance for proper sensor realignment.

5. Worn Out Rollers or Hinges

The rollers and hinges are responsible for the smooth movement of the garage door along the tracks. If these components become worn out or damaged, it can cause the door to stop when opening.

Signs of Worn Out Rollers or Hinges

Signs of worn-out rollers or hinges include excessive noise when opening or closing the door, difficulty in moving the door manually, or visible signs of wear and tear. If you notice any of these signs, it’s important to replace the worn-out components to ensure the smooth operation of your garage door.

Replacing Rollers and Hinges

Replacing worn-out rollers and hinges is a relatively simple process that can be done by most homeowners. Start by securing the door in place to prevent it from falling, then remove the old roller or hinge and replace it with a new one. It’s important to use the correct size and type of replacement component for optimal performance.

6. Damaged Garage Door Cable

The garage door cable is responsible for lifting and lowering the door. If the cable becomes damaged or broken, it can cause the door to stop when opening.

Symptoms of Damaged Garage Door Cable

Signs of a damaged garage door cable include the door being unbalanced or slanted, frayed or broken cables, or the door falling suddenly when opening or closing. If you suspect a damaged cable, it’s important to avoid using the door and call a professional for cable replacement.

Calling a Professional for Cable Replacement

Replacing a damaged garage door cable is not a DIY task and should be left to professionals. Garage door cables are under high tension and can cause serious injuries if mishandled. A trained technician will have the knowledge and expertise to safely replace the damaged cable and ensure the proper functioning of your garage door.

7. Malfunctioning Limit Switch

The limit switch in a garage door opener is responsible for setting the limits of the door’s movement. If the limit switch malfunctions, it can cause the door to stop when opening.

Problems Caused by a Malfunctioning Limit Switch

When the limit switch malfunctions, it may not accurately determine the limits of the door’s movement. This can cause the door to stop prematurely when opening, even if it has not reached the intended height. Adjusting or replacing the limit switch can help resolve this issue.

Adjusting or Replacing the Limit Switch

To adjust the limit switch, start by consulting the manufacturer’s instructions for your specific model. This will provide detailed steps on how to properly adjust the switch to ensure the door opens and closes to the desired height. If adjusting the switch does not resolve the issue, it may be necessary to replace the limit switch altogether.

8. Power Supply Issues

Issues with the power supply can also cause a garage door to stop when opening. This can be due to several factors, including a faulty power outlet, a tripped circuit breaker, or problems with the electrical wiring.

Checking Power Source

Start by checking the power source for your garage door opener. Ensure that the power cord is securely plugged into a functioning power outlet. If you are using an extension cord, make sure it is rated for the required power output.

Resetting Circuit Breakers or Fuses

If the garage door opener is not receiving power, it may be due to a tripped circuit breaker or blown fuse. Check the circuit breaker panel or fuse box and reset any tripped breakers or replace any blown fuses. This can often resolve power supply issues and get your garage door opener working again.

Electrical Wiring Inspection

If you have checked the power supply and reset any tripped breakers or blown fuses, but the garage door opener still does not receive power, there may be a problem with the electrical wiring. Inspecting the wiring for any damage or loose connections can help identify and resolve the issue. However, it’s important to note that electrical repairs should be done by a licensed electrician to ensure safety and compliance with local regulations.
