13 Reasons Why Your Garage Door Won't Close & How to Fix Them

Obstruction in the Door Path

An often overlooked but crucial factor in a garage door's smooth operation is the potential for obstructions in its path. Even seemingly insignificant objects or debris can impede the door's movement, preventing it from closing properly. Regular inspection of the door's path is essential to identify and remove any obstacles that might hinder its function. 

Misaligned Sensors

Misaligned sensors pose a significant threat to the proper functioning of modern garage doors. These safety sensors, designed to prevent accidents, must be precisely aligned. Any deviation can result in the door failing to close or operate correctly, compromising the safety features integral to the garage door system. Usually positioned at the bottom corners on either side of the garage door, both sensors should be oriented to face each other along an invisible line.

Sensor Interference

Similarly, sensor interference can disrupt the functionality of garage door safety sensors. External factors like dirt or spider webs can obstruct these sensors. Regularly cleaning and maintaining the sensors is essential to prevent interference and can help ensure your garage door closes without a hitch. 

Broken Springs

Broken springs in a garage door jeopardize its proper operation. These essential components, under constant tension, support the door's weight. When damaged, the door may not close securely or may exhibit erratic behavior. To fix broken springs, it’s important to consult a professional garage door technician for safe and effective replacement.

Malfunctioning Remote Control 

If your garage door remote malfunctions, troubleshoot by checking the batteries, ensuring the remote is within range, and reprogramming it if necessary. If problems persist, consider replacing the batteries or obtaining a new remote.

Power Issues

In the event of power issues with your garage door, start by checking the power source. Ensure the garage door opener is plugged in and verify the circuit breaker hasn't tripped. If it has, reset it to restore power.

Limit Switches

Limit switches in a garage door opener determine the door's range of movement. If misconfigured, the door may not close properly. Ensure the switches are correctly set to dictate the door's open and close positions. Adjust them as needed to guarantee the door moves through its full range effectively.

Track Misalignment

Track misalignment can impede your garage door's smooth movement. Inspect both tracks for debris or misalignment. If needed, loosen the bolts, realign the tracks, and tighten the bolts. Ensure they are level and parallel for optimal door performance. For extensive track alignment problems or if you're unsure, it's recommended to call a professional garage door repair company to ensure a safe and effective resolution.

Damaged Rollers

Worn-out or damaged rollers in your garage door can cause it to become stuck or operate unevenly. Regularly inspect the rollers for signs of wear and tear, and replace damaged ones promptly to ensure the door moves smoothly and functions efficiently.

Faulty Cables

Garage door cables are vital for the smooth operation of the door, lifting and lowering it along tracks. Positioned at the door's bottom corners, they navigate pulleys or wind on a drum. Regularly inspect for wear, fraying, or rust, and avoid using the automatic operator if a cable breaks, signaling the need for prompt servicing or replacement.
