Having an electric garage door offers convenience and security to homeowners. However, it can be frustrating when your garage door won’t close all the way. In this article, we will explore some common reasons why electric garage doors fail to close properly and provide troubleshooting tips to help you resolve the issue.

1. Sensor Misalignment

One of the most common reasons why an electric garage door won’t close all the way is sensor misalignment. The sensors, located on either side of the garage door, send an invisible beam to each other. If this beam is interrupted, the door won’t close. Check if the sensors are aligned properly and free from any obstructions.

2. Dirty or Blocked Sensors

Another reason for sensor-related issues is dirt or debris blocking the sensors. Over time, dust, dirt, or spider webs can accumulate on the sensors, preventing them from functioning correctly. Clean the sensors with a soft cloth and ensure there are no obstructions in their path.

3. Sensor Wiring Problems

If the sensors appear to be clean and aligned, the issue could be with the wiring. Check the sensor wiring for any loose or damaged connections. Make sure all wires are securely connected and replace any damaged wires if necessary.

4. Limit Switch Adjustment

Limit switches determine the opening and closing positions of the garage door. If the limit switch is incorrectly set, it can prevent the door from closing all the way. Consult your garage door opener’s manual to adjust the limit switch settings correctly.

5. Obstructed Door Track

An obstruction in the door track can also prevent the garage door from closing properly. Inspect the tracks for any debris, such as leaves or small objects, and remove them. Lubricate the tracks with a silicone-based lubricant to ensure smooth operation.

6. Damaged Rollers or Hinges

Worn-out or damaged rollers and hinges can cause the garage door to get stuck, preventing it from closing completely. Inspect these components for any signs of wear or damage and replace them if necessary.

7. Broken Springs

Garage door springs play a crucial role in lifting and lowering the door. If a spring is broken or damaged, it can cause the door to malfunction. If you suspect a broken spring, it is best to call a professional garage door technician to replace it safely.

8. Malfunctioning Garage Door Opener

If none of the above troubleshooting steps resolve the issue, the problem could lie with the garage door opener itself. It may require professional inspection and repair to fix any internal malfunctions.

9. Power Supply Issues

Ensure that your garage door opener is receiving power. Check if the circuit breaker or fuse connected to the opener hasn’t tripped or blown. If it has, reset the breaker or replace the fuse.

10. Call a Professional

If you have exhausted all troubleshooting options and your electric garage door still won’t close all the way, it is time to call a professional garage door repair technician. They have the expertise and tools to diagnose and fix more complex issues.


Dealing with an electric garage door that won’t close all the way can be frustrating, but by following the troubleshooting tips mentioned above, you can often resolve the issue on your own. Remember to prioritize safety and consult a professional if needed. Enjoy the convenience and security of having a fully functional electric garage door!
