Garage Door Only Opens 2 Inches – Troubleshooting and Solutions

Facing an issue where your garage door only opens 2 inches can be frustrating and puzzling. A fully functioning garage door is crucial for daily convenience and security.

In this article, we will explore the common reasons behind a garage door only opening 2 inches and provide practical troubleshooting steps to help you resolve the issue.

Garage Door Only Opens 2 Inches

Possible Causes of the Problem:

Broken Torsion Springs:
One of the most common culprits behind a partially opening garage door is a broken torsion spring. Torsion springs are responsible for counterbalancing the weight of the door, making it easier to open and close. When a torsion spring breaks, it disrupts the door’s balance, making it difficult to fully open the door.

Misaligned Safety Sensors:
Safety sensors are present near the bottom of garage doors on either side. These sensors detect objects or obstructions in the door’s path and prevent it from closing completely. If the sensors are misaligned or blocked, they may mistakenly signal the door to stop opening, limiting its movement to just a few inches.

Damaged Tracks or Rollers:
The garage door operates on tracks with rollers that guide its movement. If the tracks are bent, warped, or damaged, the door may get stuck while opening, restricting its travel. Similarly, worn-out or damaged rollers can hinder the smooth movement of the door, causing it to stop after opening just a few inches.

Troubleshooting Steps:

Check Torsion Springs:
Inspect the torsion springs for any signs of damage or breakage. Broken springs should be replaced by a professional garage door technician, as handling them can be dangerous due to their high tension.

Verify Safety Sensor Alignment:
Ensure proper alignment and freedom from obstructions for the safety sensors. Clean the sensor lenses and adjust their positions if necessary. A solid green light on both sensors indicates proper alignment.

Examine Tracks and Rollers:
Inspect the tracks for any damage or misalignment. Use a level to check if they are straight and properly aligned. Additionally, examine the rollers for signs of wear or damage, and replace them if needed.
