Troubleshooting a Belt Drive Garage Door Opener

A belt drive garage door opener is one of the 3 types of door openers available to home owners. The other two, the chain driven and the screw drive openers, have their own specific uses and application. Since the garage door one of the largest moving parts in your home and an entry point for your home, you want to feel confident that everything is going to work the way it should. Troubleshooting something means either seeing problems before they happen or noticing what is wrong so you can fix is quickly. Here are a few problems associated with a belt drive garage door opener for easy troubleshooting.

Dirty Belts

The garage door opener is not a set-it-and-forget it type of appliance. Since it is in the garage is going to mean, it will need to be periodically cleaned to ensure longevity and problem-free use. Dust can accumulate on the wheel that drives the belt. Clean this out with some air or a rag. Wipe down the belt itself to keep it from rubbing on any dirt particles and fraying.

Squeaky Drive

When lowering the garage door, a noise or squeak it can be a sign of problems that are to come. In this case, you will need to lightly oil the wheel that turns the belt to keep it turning and free of accumulating dirt.

Bouncing Door

If the door continually starts and stop when you raise it, the bouncing motion can damage the door. This is usually caused by the motor not working properly, or something is interfering with the belt drive. Inspect the belt to check for any type of obstruction. If there is nothing that can keep the door from raising smoothly, you then have a problem with the motor itself.

Binding of Belt

When the belt begins to bind and not work as smoothly as when it was first installed, it is an indication that something has gotten out of alignment. This is usually a product of the rail assembly being loose. Tightening the bolts with a ratchet will help to ease the binding problem.

Door Closes Hard

After several uses, you might see that the door begins to close hard onto the cement floor of the garage. This can be a problem with two different components. The first is the sensitivity of the force adjustment that is located on the back of the motor housing. Adjust this so that the door will settle easily onto the floor. The second reason is through a loosening of the radial arm that holds the door to the belt. Tighten the bolts on this and check for any wear or elongation of the bolt hole.

Door Does Not Open

If you press the opener button and nothing happens, you should first check to see that the unit is plugged in. Check the fuse to see that nothing has tripped. Check the gears that turn the belt assembly to see if there are obstructions. Clean out the IR sensors to make sure there are no obstructions. You should also check to make sure the manual disconnect has not been pulled. If all of these issues are in good working order, you will have a problem with the motor itself.
