Why Won’t My Garage Door Close?

Common Issues & Fixes Explained

A faulty garage door can be both irritating and dangerous to your safety. If you have the question, "Why can't I get My Garage Door to close?" There are others going through the same thing. This is a household issue that thousands of people face each year. First of all, fixing any garage door problem starts with identifying the precise cause of the issue.

This article will examine the most common problems and their practical solutions.

Common Issues – Reasons Your Garage Door Refuses to Close

Calm down and try to figure out the reason for the malfunction first.

1. Garage Door Sensor Problem: The Most Common Culprit

One of the most frequent causes of garage door closing issues is a malfunctioning safety sensor. There are sensors connected to the Garage Door on each side, near the floor, to keep it from closing on anything below it.

• Any dirt or debris on the lens may result in a sensor error from the garage door.
• If the sensors on the garage door are not aligned, the light on your opener may start flashing.
• Due to wiring issues, the sensor might fail to work completely.

Fix: Wipe the sensors with a gentle cloth and be sure the LED lights are not flickering. If you see the light blinking, keep adjusting the sensors until the lights are still.

2. Garage Door Photo Eye Problem

A garage door photo eye problem is directly related to sensor malfunctions. These photo eyes must be appropriately aligned—any deviation can prevent the garage door from closing.

Signs:

• The garage door won’t shut completely
• The garage door won’t close, and the light blinks
• The garage door closes partially, then reverses

Fix: Use a tape measure to ensure both photo eyes are the same height. Adjust them until aligned and stable.

3. Garage Door Alignment Issues

When your garage door has alignment issues, it might move crookedly or stop midway. This strain can cause the opener to shut down for safety.

Common Causes:

• Loose or snapped cables
• Worn-out rollers
• Bent or damaged tracks

Fix: Inspect the tracks and cables for wear or damage. If you're unsure, call a professional for realignment or cable replacement.

4. Garage Door Track Obstruction

Even minor debris can cause a garage door track obstruction, which might trigger a reversal or cause the garage door to become stuck open.

Fix: Check both tracks for tools, rocks, or buildup. Clear out anything in the way and ensure the rollers move freely.

5. Garage Door Limit Switch Issue

The garage door may not be able to recognize when to stop due to a problem with the limit switch. The garage door may stay open if the opener is set too high, causing it to believe the floor has been reached.

Fix: Look for your opener's limit switch adjustment knobs. Lower the down-limit with a screwdriver and give the garage door another little test.

6. Garage Door Won’t Close with Remote

If your garage door won’t close with the remote, try these steps:

• Replace the batteries
• Check for interference from nearby devices
• Reprogram the remote

Fix: If your wall control works but not the remote, the issue likely lies in remote programming or weak batteries.

7. Garage Door Won’t Close Unless Holding Button

This issue typically points to a sensor problem. If the wall control bypasses safety features, your garage door won’t close unless you hold the button.

Fix: Double-check the sensor alignment and wiring. Clean away any dust, webs, or obstructions between them.

8. Garage Door Stuck Open

A garage door stuck open can be due to mechanical failures like:

• Broken torsion or extension springs
• Power interruption
• Opener motor burnout

Fix: Use the emergency release cord to attempt manual operation. If it doesn’t budge, your springs may be broken—call a pro immediately.

9. Garage Door Reversing When Closing

If the garage door reverses when closing, it's a protective response to friction or misalignment.

Fix: Clean and lubricate the tracks and rollers. Also, recheck the garage door limit switch and sensor alignment.

10. Garage Door Opener Light Flashing

When the garage door opener light is flashing, your system alerts you to a fault, commonly a garage door safety sensor malfunction.

Fix: Refer to your opener’s manual. Most models flash 10 times to indicate a sensor problem.

When to Call a Professional

Some garage door closing issues are easy to fix, but others need a pro. Contact a technician if:

• The garage door won’t shut completely, even after troubleshooting
• The garage door is off its tracks
• The garage door opener won’t close the garage door, and only hums
• The springs or cables are visibly broken
