Why won’t my garage door close?


If you’re experiencing trouble with your garage door not closing, it can be frustrating and inconvenient. Several factors can contribute to this issue, ranging from simple to more complex problems. In this article, we will explore some common reasons why your garage door won’t close and provide possible solutions to help you resolve the issue.

1. Sensor Malfunction

One of the most common reasons why a garage door won’t close is a malfunctioning sensor. Garage doors are equipped with safety sensors that detect objects or obstructions in the door’s path. These sensors are usually located near the bottom of the door tracks, on either side. If something is blocking the sensor’s path, the door will not close to prevent potential accidents.

Possible solutions: Check if there are any objects obstructing the sensor’s path, such as debris, leaves, or spider webs. Clean the sensors carefully and ensure they are properly aligned. If the sensors are misaligned, adjust them until the indicator lights are solid and not blinking.

2. Misaligned Tracks

Another common issue that can prevent a garage door from closing is misaligned tracks. Over time, the tracks that guide the door’s movement can become misaligned due to regular use or accidental bumps.

Possible solutions: Inspect the tracks for any signs of misalignment, such as gaps or bends. If you notice any issues, use a rubber mallet or a hammer with a block of wood to gently tap the tracks back into alignment. Ensure the tracks are level and parallel to each other. Lubricate the tracks with a silicone-based lubricant to reduce friction and facilitate smooth movement.

3. Broken Springs

Garage doors are equipped with springs that help counterbalance the weight of the door, making it easier to open and close. If one or both of the springs break, it can cause the door to become unbalanced and prevent it from closing properly.

Possible solutions: Broken springs should be replaced by a professional garage door technician. Attempting to replace them yourself can be dangerous due to the high tension involved. Contact a reputable garage door repair service to inspect and replace the broken springs.

4. Power Issues

Sometimes, a garage door may not close due to power-related issues. If there is a power outage or if the garage door opener is not receiving power, it can affect the door’s functionality.

Possible solutions: Check if the power source is functioning correctly. Ensure that the garage door opener is plugged in and that the circuit breaker or fuse controlling the opener is not tripped. If necessary, reset the circuit breaker or replace the fuse. Consider using a backup power source, such as a battery backup system, to ensure your garage door can function during power outages.

5. Remote Control Problems

Issues with the remote control or the garage door opener itself can also prevent the door from closing. This can be due to a variety of reasons, such as dead batteries, signal interference, or programming errors.

Possible solutions: Replace the batteries in the remote control and ensure they are properly inserted. Check for any signal interference, such as nearby electronics or devices that may be affecting the remote’s signal. Reprogram the remote control according to the manufacturer’s instructions. If the garage door opener itself is malfunctioning, consider contacting a professional for repair or replacement.


In conclusion, a garage door not closing can be attributed to various factors, including sensor malfunctions, misaligned tracks, broken springs, power issues, or problems with the remote control. By identifying the specific issue and following the suggested solutions, you can troubleshoot and resolve the problem effectively. However, if you are unsure or uncomfortable with performing any repairs yourself, it is always recommended to seek professional assistance to ensure safety and proper resolution.
