Top Reasons Why Your Garage Door Wouldn't Close

There's nothing more frustrating than a garage door that refuses to close when you need it to. If you find yourself in such a situation, don't panic! In this blog post, we will explore some of the most common reasons why your garage door wouldn't close. By understanding these issues and their potential solutions, you can troubleshoot and resolve the problem, restoring the functionality and security of your garage door. Let's dive in and uncover the culprits behind this inconvenience.

Sensor Misalignment

Garage doors are equipped with safety sensors located near the floor on both sides of the door. These sensors transmit an infrared beam to detect any obstructions in the door's path. If the sensors are misaligned or blocked by debris, the door's safety mechanism will prevent it from closing. Check the sensor alignment and clean any dirt or debris obstructing the sensors to restore their proper function.

Sensor Malfunction

In some cases, the sensors themselves may be faulty or malfunctioning. Inspect the sensors for any signs of damage or loose wiring connections. Ensure that the sensors' indicator lights are illuminated, indicating a properly aligned beam. If the sensors are not working despite being aligned and clean, it may be necessary to replace them.

Limit Switch Issues

Garage doors are equipped with limit switches that control the door's open and close positions. If these switches are misadjusted, the door may not close fully. Locate the limit switch adjustment screws on the opener unit and carefully adjust them according to the manufacturer's instructions. Small adjustments can make a significant difference in the door's operation.

Track Obstruction or Misalignment

An obstruction or misalignment in the garage door tracks can prevent it from closing smoothly. Inspect the tracks for any objects, debris, or bent sections that could be causing an obstruction. Use a level to ensure the tracks are properly aligned. If you notice any misalignment or significant damage to the tracks, it's best to seek professional assistance for repairs.

Broken Springs or Cables

Garage door springs and garage door cables play a crucial role in supporting the weight of the garage door. If they are damaged or broken, the door may not close properly. Examine the springs and cables for any signs of wear, fraying, or breakage. If you suspect an issue with these components, it's crucial to have them replaced by a trained professional due to the high tension involved.

Malfunctioning Garage Door Opener

A malfunctioning garage door opener can also be a reason for the door not closing. Check the opener for any visible signs of damage or loose connections. Ensure that the motor and control board are functioning correctly. If you're unable to identify the problem or if the opener requires repairs, contact a professional garage door technician for assistance.
Sometimes, a simple power interruption or electrical problem can prevent the garage door from closing. Check the power supply to the opener, ensuring it's properly connected and functioning. If there is an electrical issue, such as a blown fuse or tripped circuit breaker, resolve it accordingly. Additionally, inspect the control panel and remote batteries to ensure they have sufficient power.


When your garage door refuses to close, it can be frustrating and inconvenient. By understanding the common reasons behind this issue, such as sensor misalignment, malfunctioning sensors, limit switch problems, track obstructions or misalignment, broken springs or cables, malfunctioning opener, and power interruptions, you can effectively troubleshoot and resolve the problem. Remember to exercise caution when inspecting and addressing any garage door issues. If you're unsure or unable to resolve the problem yourself, don't hesitate to seek professional assistance from our professional technicians.
