Step-by-step Instructions for How to Adjust a Roll Up Garage Door

Step 1: Inspect the Door

Start by inspecting the door and its components. Look for any signs of damage or wear and tear that may need to be addressed before making any adjustments. To safely release tension from the door springs, use a winding bar to loosen the set screws on either side of the spring core tube. This will allow you to adjust the tension safely.

Step 2: Adjust The Spring Tension

Your garage door should come with a spring setting chart that will guide you on how much tension is recommended for your type of door. Once you’ve identified the appropriate amount of tension, use a socket wrench to turn the winding cone on either side of the spring core tube. This will adjust the tension in the spring.

Step 3: Adjust The Chain Or Track

If your door has a chain or track system, use a socket wrench to turn the set screws on either side of the chain or track to adjust it. Ensure that these are securely tightened before moving on to the next step, as this is vital for keeping the door in proper alignment.

Step 4: Adjust The Limit Switch

To adjust the limit switch, use a flat-head screwdriver to turn the adjusting screws on either side of the limit switch until they are both securely tightened. This will help determine how far up and down your garage door should travel when you open or close it.

Step 5: Test The Door

With the limit switch adjusted, close the door to test it out and ensure that it is working properly. Open and close the door a few times to confirm everything is working. Depending on the garage door type you have, other components may need to be adjusted. Check the manufacturer’s instructions for additional details on correctly adjusting these parts.

Step 6: Re-tighten The Tension

Now that all of the adjustments have been made, it is important to re-tighten the tension in the door springs. Use a winding bar to secure the set screws on either side of the spring core tube.

Once the tension has been re-tightened, check and adjust the balance of your garage door. This can be done by manually opening and closing it a few times to ensure that it is operating smoothly.

Finally, having a professional inspection of your garage door is always a good idea. This will help ensure that all of the components are properly adjusted and functioning correctly. By following these steps, you can adjust your roll-up garage door safely and easily.

Is There a Way to Test if Your Adjustments Were Successful? 

Once you have made your adjustments to your roll-up garage door, it is important to know that they were successful. To do this, test the closing and opening functions of the door.

Test the Closing and Opening Functions

Once you initiate the close command from the opener, release it after a few seconds and make sure that it stops at a point where there’s about a one-inch gap between the door and the floor. Test to make sure that your garage door is also opening fully, completing its cycle before opening again.

It is important to note that a roll-up garage door should never close all the way since this may cause damage. The gap between the floor and the door should remain at around one inch, so it will not close completely.

If your garage door does close all the way, you may need to make more adjustments or contact a professional for help. By understanding how to adjust a roll-up garage door and testing your adjustments’ success, you can ensure that your garage door operates safely and correctly.

How Often Should You Adjust Your Roll-Up Garage Door? 

Adjusting your roll-up garage door should be done regularly, annually. This will ensure that it continues to operate smoothly and efficiently. If you’ve recently noticed any changes in how the door operates, or if you feel like it’s not working as well as it used to, then it’s time to adjust your door.

On top of regular adjustments, you should also inspect and lubricate the different components of the door at least once a year. This will help to make sure that everything is working properly and prevent any potential problems down the road.

Anytime you adjust the garage door, it’s important to be careful and mindful of your safety. Make sure you read the owner’s manual thoroughly and follow all instructions closely.

Never attempt any adjustments while the door is in motion or before disconnecting power from the system. If you feel like you can’t properly adjust the door yourself, it’s always best to call a professional.

What is the Best Way to Ensure That Your roll-up garage Door is Adjusted Correctly?

The best way to ensure that your roll-up garage door is adjusted correctly is by adjusting it gradually. This means making small adjustments each time you open or close the door and periodically checking the position against the frame and its rollers when it is in a fully opened or closed state.

Making Sure That It is Completely Closed

To adjust the door, you should start by making sure that it is completely closed and disengaged from the opener. Then, locate the adjustment screws at the top of each side of the garage door frame. If there are no screws on either side, your roll-up garage door might not be adjustable.

Once you have located the adjustment screws, use a flathead screwdriver to loosen them slightly. Then, open and close the roll-up garage door several times to ensure that it is moving smoothly in both directions.

As you open and close the door, use the adjustment screws to adjust the tension of each side until it moves properly without any sticking or binding.

Finally, check the position of the door against the frame and its rollers. Ensure that there are no gaps between them, as this could cause a misalignment of your roll-up garage door over time.

 Process Can Be Complicated and Time-consuming


One downside of adjusting a roll-up garage door is that the process can be complicated and time-consuming. Adjusting the tension on the springs requires special tools and knowledge of basic mechanics, so it’s not an ideal DIY project for inexperienced homeowners.

In conclusion, adjusting a roll-up garage door is not a difficult task. All you need is the right tools, patience, and good judgment to make sure that the adjustment produces desirable results. Through this article, we have seen to adjust a roll-up garage door by adjusting both the spring tension and the force settings.

It’s important to remember that it’s better to seek help from a professional if you’re not confident in completing the task yourself. I hope this article has been beneficial for learning how to adjust a roll up garage door. Make Sure the precautionary measures are followed chronologically.
