Why Your Garage Door Only Opens A Foot and How to Fix It? Troubleshooting Guide

Understanding Why Your Garage Door Only Opens A Foot

Misaligned Safety Sensors

One of the most common reasons for a garage door to stop after only opening a foot is misaligned safety sensors. These sensors, typically located near the bottom of the garage door tracks, are designed to detect obstructions in the door’s path. If they are misaligned or obstructed themselves, they may mistakenly signal the door to stop moving.

Broken Springs

Another possible cause of limited garage door movement is broken or damaged springs. Springs are responsible for counterbalancing the weight of the door and assisting in its smooth operation. When a spring breaks, the door may struggle to open fully, resulting in it stopping prematurely.

Track Obstructions

Obstructions in the garage door tracks can also prevent the door from opening fully. Common obstructions include debris, dirt, or even small objects that have become lodged in the tracks. Inspect the tracks carefully and remove any obstacles that may be impeding the door’s movement.

Opener Limit Settings

The opener unit itself may have limit settings that dictate how far the door opens and closes. If these settings are improperly adjusted, the door may stop short of its intended opening height. Consult your garage door opener manual to learn how to adjust the limit settings correctly.
