Garage Door Won’t Close All the Way and Goes Back Up

When your garage door won’t close all the way and goes back up, it can be a frustrating problem. This common issue can stem from several factors, including safety sensor malfunctions, track obstructions, and incorrect limit settings. Below, we delve into the reasons behind this problem and how to fix it.

Causes and Solutions for a Garage Door That Won’t Close

Obstructed Path

One of the simplest reasons a garage door won’t close is an obstruction in its path. Even small items like debris or garden tools can trigger the safety sensors and cause the door to reverse. Check for any objects blocking the door’s path and remove them to resolve the issue​.

Misaligned or Faulty Safety Sensors

Garage doors are equipped with safety sensors to prevent accidents. If these sensors are misaligned or malfunctioning, the door won’t close. Misalignment can often be fixed by adjusting the sensors so that they face each other directly. Cleaning the sensor lenses can also help if dust or cobwebs are obstructing the signal.

Limit Switch Settings

The limit switch determines how far the garage door should travel to close completely. If this setting is off, the door might close and then reopen. Adjusting the limit switch settings according to the garage door opener’s manual can usually fix this problem.

Damaged or Worn-Out Cables and Springs

Garage door cables and springs play a crucial role in its operation. Over time, these components can wear out or break, leading to issues with the door closing properly. Inspect the cables and springs for any signs of damage and replace them if necessary.

Track Issues

Bent or damaged tracks can also prevent a garage door from closing all the way. Inspect the tracks for any bends or obstructions and straighten them if needed. Regular maintenance can help keep the tracks in good condition.
