How to Fix a Garage Door That Won’t Close Completely

Having a garage door that won’t close completely can be frustrating, especially if you need to secure your garage at the end of the day. Fortunately, there are several common reasons why a garage door might not close, and most of them can be fixed without calling in a professional. In this post, we’ll walk you through the steps to troubleshoot and fix your garage door so it closes properly again.

Common Reasons a Garage Door Won’t Close Completely

Before diving into fixes, it’s important to understand the root causes. Here are some of the most common issues that may cause a garage door to stop closing fully:

  • Obstructed Sensors: Garage doors typically have safety sensors on either side of the door. These sensors are designed to stop the door from closing if there’s an obstruction, like debris or dirt, blocking the sensor’s beam.

  • Misaligned Tracks: If the tracks guiding the garage door are misaligned or bent, the door may not be able to close properly.

  • Malfunctioning Springs: The springs help support the weight of the door. If one or both springs are broken or worn out, the door might not close fully.

  • Worn Out Rollers: The rollers guide the door along the tracks. When they wear out or get damaged, the door can have difficulty moving, leading to incomplete closure.

  • Faulty Wall Switch or Remote: Sometimes, the issue is as simple as a malfunctioning switch or remote control, not sending the correct signal to the opener.

Steps to Fix a Garage Door That Won’t Close Completely

Step 1: Check the Sensors for Obstructions
One of the most common reasons a garage door won’t close is because the safety sensors are obstructed. These sensors are typically located about six inches off the ground, one on each side of the door. Make sure there is nothing blocking the sensor’s line of sight—whether it’s dust, spider webs, or other debris.

  • Clean the lenses: Use a soft cloth to gently clean both the sensors. Dirt or cobwebs on the lenses can block the sensor’s signal.

  • Align the sensors: Ensure both sensors are properly aligned. If they’re slightly off, the door won’t close. You may need to adjust them by loosening the mounting screws and repositioning them.

Step 2: Inspect the Tracks
Misaligned or bent tracks are another frequent cause of a garage door not closing properly. Inspect both sides of the track for visible damage, dirt buildup, or anything that could block the door’s path.

  • Check for obstructions: Look along the tracks to see if there’s any debris, such as leaves, dirt, or parts of the door hardware, that could prevent the door from closing.

  • Realign the tracks: If you notice any misalignment, try to gently tap the track back into position with a rubber mallet. Be sure to align both the horizontal and vertical tracks so the door moves smoothly along them.

  • Lubricate the tracks: Use a lubricant specifically made for garage doors to keep the tracks and rollers moving smoothly.

Step 3: Examine the Springs
The springs are responsible for supporting the weight of the garage door. If a spring breaks or becomes too worn, it can affect how the door operates. Broken springs can also be dangerous to replace yourself, so it’s best to contact a professional if you suspect the springs are the issue.

  • Look for visible signs of damage: If you see a broken spring or hear an unusual sound when the door is operating, the springs might need replacement.

  • Test the door manually: Disconnect the opener by pulling the emergency release cord. Manually lift the door and see if it feels uneven or heavy. This could indicate an issue with the springs.

Step 4: Check the Rollers
Worn-out rollers can also prevent the garage door from closing properly. These rollers help the door move smoothly along the tracks. Over time, they can wear down and become less effective.

  • Inspect the rollers: Check the rollers for visible signs of wear and tear. If they’re cracked or chipped, they may need to be replaced.

  • Lubricate the rollers: Apply lubricant to the rollers to ensure smooth operation. Be careful not to over-lubricate, as excess grease can attract dirt and debris.

Step 5: Test the Wall Switch and Remote
If your garage door still won’t close, it could be an issue with the wall switch or the remote control. Test both to ensure they are working properly.

  • Check the wall switch: Test the switch by pressing it multiple times to see if the door responds. If the door works intermittently or not at all, the switch could be faulty.

  • Test the remote control: Replace the battery in the remote control and try again. If the remote still doesn’t work, you may need to reprogram it or replace it entirely.

Step 6: Reset the Garage Door Opener
Sometimes, the issue may lie with the garage door opener itself. A simple reset could do the trick.

  • Unplug the opener: Disconnect the power to the garage door opener for about 10 seconds, then plug it back in.

  • Test the door again: After resetting the opener, test the door to see if it now closes completely.
