Why Is My Garage Door Not Closing?

September 20, 2021

Few things are as frustrating as a garage door that won’t close all the way, and it’s particularly annoying if you’re rushing out trying to make it to school or work. There are several potential reasons why your garage door is not closing—read on to learn more about the possible issues.

Check the sensors

The most common reason that a garage door won’t close is an issue with the safety sensors that tell the door to stop closing when something’s in the way. Wipe the lenses down with a soft cloth to clean them up, and then make sure the sensors on both sides of the door are aligned with one another.

Inspect the tracks and rollers

Dirty rollers or bent tracks can also prevent your garage door from closing all the way. Check the tracks to ensure there isn’t any debris preventing the rollers from moving freely and that both tracks are even. You may be able to bend a bent track by hand, but this is typically a job reserved for a garage door repairman.

Look at the trolley

The trolley is the mechanism that connects the garage door to the trolley. It usually has a rope dangling down, which is responsible for engaging and disengaging the door from the chain-driven door opener. If the door is moving by hand, the trolley is likely in bypass mode. Simply pull the rope toward the door to take the trolley out of bypass mode. The door should function again after you hit your garage door button.

Reset the remote

The problem may lie with the remote control and not the opener itself. Replace the batteries to see if that works. If not, you’ll need to reprogram the remote by opening the rear flap on the opener and pressing the “learn” button. Press and hold the button until a light flashes, and then press a button on your remote. Your remote should be good to go.

Adjust the limit screws

The issue may be with the limit screws—the screws that tell the garage door opener how far to open and close. You can adjust these screws by opening the rear flap on the garage door opener. You’ll see two plastic screws labeled “up” and “down.” Simply use a flathead screwdriver to twist the “down” screw in quarter-turn increments. Test and repeat this process until the door closes.
