How to Replace Garage Door Belt in 6 Steps

Now that you know why you might want to replace your garage door belt, let’s take a look at the steps involved in doing so. Here’s how to replace your old garage door belt:

Step 1: Disconnect the Power 

Begin by disconnecting the power to the garage door. If it’s set up to an electric opener, unplug the cord or turn off the breaker in your home’s electrical panel. If you don’t want to deal with electricity, then use a manual override switch that disconnects power from your garage door operator.

Step 2: Open the Garage Door 

Open your garage door fully and then lock it into place by putting a c-clamp on both sides of the tracks. This will prevent the door from moving when you’re working on it. Also, it’s a good idea to set up a ladder underneath the door so that you can safely climb up and down when needed.

Step 3: Examine the Belt for Wear & Tear 

Examine your garage door belt for any signs of damage or wear and tear. If there are any visible cracks or fraying, then it’s time to get a new belt. Make sure to purchase one that is compatible with your garage door model.

Step 4: Remove the Old Belt 

To remove the old belt, use an adjustable wrench to loosen and remove the bolts located on either side of the garage door track. Then, detach the existing belt by pulling it away from both sides of the track.

Step 5: Install the New Belt

Carefully fit your new garage door belt into place on both sides of the track. Make sure that it’s firmly attached and that all of the bolts are tightened securely. Make sure you are using the right size bolts for your new belt.

Step 6: Test the Belt

Once the new belt is installed, plug in or turn on the power to your garage door and test out the belt’s operation. If it runs smoothly without any issues, then you’ve successfully replaced your garage door belt!

Some Additional Tips to Replace Garage Door Belt

1. Do Not Over-Tighten the Belt

When replacing a garage door belt, it is important to avoid over-tightening the belt. Over-tightening the belt can cause it to stretch and weaken, eventually leading to failure or breakage.

Also, be sure to refer to the manufacturer’s instructions when tightening the belt, as different models will vary in how tight they need to be.

2. Inspect and Clean Tracks

Garage door tracks should always be inspected and cleaned prior to the installation of a new garage door belt. If the tracks are not clean then dirt, debris, and other contaminants can interfere with the proper operation of the doors.

3. Check For Cracks or Splits in the Belt

Inspect the new replacement belt for any visible cracks or splits, as these can lead to breakage when in use. If there is any doubt about the integrity of the belt then it should be discarded and a new one obtained.

4. Test The Door After Installation

Once the garage door belt has been installed correctly, it is important to test the door for correct operation and alignment. This will ensure that the door is functioning properly and can help to identify any potential problems with the belt prior to long-term use.

Following these simple tips should help you successfully replace your garage door belt, thereby ensuring that it functions correctly for many years to come. If in doubt about how to perform any of the steps involved in replacing the belt, refer to the instructions given by the garage door manufacturer. 

If ever you feel uncomfortable or unsafe during any stage of this process, it is advised that you get professional assistance from a qualified technician. This will ensure that your garage door is installed correctly and safely.
