How Do I Check the Tension on My Garage Door?

Garage door tension is critical for smooth, balanced operation. If the tension is off, the door may open unevenly, feel heavy, or fail to stay open. Checking the tension helps identify if the springs or cables need adjustment. Here's a step-by-step guide for safely checking the tension.

Step 1: Disconnect the Opener

Pull the emergency release cord (usually red) to disconnect the door from the opener. This allows you to test it manually.

Step 2: Manually Lift the Door

Lift the door halfway: A properly tensioned door should stay in place.
Door falls shut: Spring tension is too low.
Door rises: Tension is too high.

Step 3: Observe the Movement

Open and close the door manually several times. Smooth, consistent motion indicates good tension. Jerky or uneven movement means it's time for adjustment.

Step 4: Visually Inspect the Springs

Look for gaps, rust, or uneven coils. If a spring looks damaged or stretched, it needs professional replacement.

Important Safety Note

Do not attempt to adjust torsion springs yourself. They are under extreme pressure and can cause serious injuries. Only professionals should handle spring adjustments or replacements.
