Understanding Why Your Garage Door Closes Halfway Then Opens

Common Causes

  1. Misaligned Sensors: One of the most common reasons for a garage door to close halfway and then reverse is misaligned safety sensors. These sensors, located near the bottom of the door tracks, are designed to detect obstructions in the door’s path. If they are not properly aligned or obstructed by debris, they may mistakenly signal the door to reverse.
  2. Obstructions in the Door’s Path: Another possible cause is an obstruction blocking the door’s path. This could be anything from debris or objects on the garage floor to items stored too close to the door tracks. When the door encounters an obstruction, it automatically reverses to prevent damage or injury.
  3. Broken Springs: Broken or damaged garage door springs can also cause the door to close unevenly or fail to close properly. If the springs are worn out or broken, they may not provide enough tension to support the weight of the door, causing it to close partially before reversing.
  4. Issues with the Garage Door Opener: Problems with the garage door opener, such as faulty wiring, worn-out gears, or a malfunctioning motor, can also lead to issues with door operation. If the opener is unable to function properly, it may cause the door to close partially before reversing as a safety precaution.

Troubleshooting Steps to Fix the Issue

Step 1: Check for Obstructions

Begin by inspecting the area around your garage door for any obstructions or debris that may be interfering with its operation. Remove any objects blocking the door’s path and ensure that the tracks are clear of debris.

Step 2: Verify Sensor Alignment

Inspect the safety sensors located near the bottom of the door tracks to ensure they are properly aligned and free from any obstructions. Adjust the sensors if necessary and clean any debris or dirt that may be blocking their view.

Step 3: Test the Door Manually

Manually open and close the garage door to see if you encounter any resistance or unusual noises. Pay attention to how smoothly the door operates and whether it closes evenly without any issues.

Step 4: Check the Springs

Inspect the garage door springs for signs of wear or damage, such as fraying or rusting. If you suspect a broken spring, it’s best to contact a professional garage door technician to safely replace the springs.
