How to adjust a garage door?


Adjusting a garage door is an essential maintenance task that can help ensure its smooth operation and prolong its lifespan. Whether your garage door is making unusual noises, not closing or opening properly, or showing signs of imbalance, adjusting it can often resolve these issues. In this article, we will explore the step-by-step process of adjusting a garage door to help you keep it in optimal condition.

1. Check the Balance

Step 1: Disconnect the garage door opener by pulling the release handle or unplugging it from the power source.
Step 2: Manually lift the garage door to about halfway open and let go. If the door stays in place, it is properly balanced. If it moves up or down, it indicates an imbalance.
Step 3: To adjust the balance, locate the adjustment screws on the side of the garage door opener. Turn the screws clockwise to increase the tension and counterclockwise to decrease it. Make small adjustments and test the balance after each turn.

2. Adjust the Spring Tension

Step 1: Ensure the garage door is closed and disconnect the opener.
Step 2: Locate the torsion spring above the door. Use a winding bar to insert it into one of the holes on the winding cone.
Step 3: Hold the winding bar in place and loosen the set screws on the winding cone with a wrench.
Step 4: Slowly unwind the spring by turning the winding cone counterclockwise. Be cautious as the spring will release tension.
Step 5: To increase tension, wind the spring by turning the cone clockwise. Make sure to wind it enough to balance the door but avoid overtightening.
Step 6: Once the desired tension is achieved, tighten the set screws on the winding cone.

3. Lubricate Moving Parts

Step 1: Clean the tracks and rollers using a damp cloth to remove any dirt or debris.
Step 2: Apply a silicone-based lubricant to the rollers, hinges, tracks, and springs. Avoid using oil-based lubricants as they can attract more dirt.
Step 3: Open and close the garage door several times to distribute the lubricant evenly.

4. Inspect and Adjust the Tracks

Step 1: Check the alignment of the tracks. They should be parallel and have a slight downward slope towards the back of the garage.
Step 2: Use a level to ensure the tracks are straight. If they are not, loosen the mounting brackets and gently tap them into the correct position.
Step 3: Tighten the mounting brackets once the tracks are aligned.


Regularly adjusting your garage door is crucial for its proper functioning and longevity. By following the steps outlined in this article, you can check the balance, adjust the spring tension, lubricate moving parts, and inspect and adjust the tracks. Remember to exercise caution when working with garage door components and seek professional assistance if you are unsure or uncomfortable performing any of these tasks.
