Garage Door Won’t Close Repair

A garage door that won’t close is one of the most stressful and urgent problems a homeowner can face. It’s not just an inconvenience; it’s a major security breach that leaves your home and belongings completely exposed. Whether the door reverses, stops halfway, or won’t move at all, the result is the same: a home that isn’t secure.

At Alfonso Garage Door, we specialize in diagnosing and fixing doors that refuse to close. This common problem can be caused by many issues, from simple sensor misalignment to track problems. We provide fast, same-day service throughout the Bay Area to find the root cause and, most importantly, get your garage secured immediately.

Common Causes for a Door That Won't Close

A door that won’t close is a symptom, not a single problem. The cause is most often related to the safety systems, but it can also be a sign of mechanical or opener-related issues.

Symptoms & Likely Causes:

Door Reverses Immediately (or Blinking Opener Light)

This is the most common issue, and it almost always points to your Safety Sensors. If the opener light flashes 10 times, it’s a sensor error code. The invisible beam is blocked or misaligned.

Door Stops & Reverses After Hitting the Floor

If the door closes all the way, hits the floor, and then immediately goes back up, your opener’s “close travel limit” is set incorrectly. It “thinks” the floor is an obstruction.

Door Won't Close from Remotes (But Wall Button Works)

This is often a control issue. The “Lock” or “Vacation” mode button on your main wall console may have been accidentally pressed, which locks out all remote signals.

Can I Fix It Myself?

For this issue, yes, there are several safe troubleshooting steps you should try before calling a professional. Many “won’t close” problems are simple fixes.

Safe DIY Checks:

Check for Obstructions: Look in the tracks and on the floor. Remove any items, leaves, or debris.
Clean the Sensor Lenses: The sensor "eyes" get dirty. Wipe them with a soft, clean cloth.
Check Sensor Alignment: Look at the small LED lights on both sensors. They should both be solid and bright. If one is off or flickering, gently bend the bracket by hand until both lights are solid.
Check the "Lock" Button: Look at your main wall-mounted control and make sure the "Lock" light is not on.

When to Call a Professional

If you’ve cleaned and aligned the sensors, but they still won’t light up (they may be faulty or have bad wiring).
If the door is visibly crooked or jamming in the tracks.
If the opener settings (travel limits or force) need to be adjusted.
If you’ve tried everything and it still won’t close.

What to Do Right Now If Your Door Won't Close

Follow these steps in order:

Step 1: Look for and remove any physical obstructions.
Step 2: Wipe the lenses of both safety sensors.
Step 3: Check the sensor alignment lights. Adjust them until they are both solid (e.g., one green, one amber). Try the remote again.
Step 4: If it still won't close, you can secure your door for the night by pressing and holding the main wall-mounted button. You must hold it without letting go until the door is fully closed.
Step 5: Call a professional. An overridden sensor is not a fix and leaves your door unsafe. Call Alfonso Garage Door at (408) 580-7949 for a proper diagnosis.

Preventing Future Closing Problems

Hinge failure is almost always preventable with one simple task: lubrication.

Common Causes of Failure:

Misaligned Sensors: Easily bumped by garbage cans, bikes, or kids.
Dirty Sensor Lenses: Dust, cobwebs, and pollen block the beam.
Opener "Lock" Mode: The wall panel lock is accidentally on.
Opener Travel Limits: The opener's settings are off and it "thinks" the floor is an obstruction.

A Seasonal Warning for Homeowners

As the seasons change, two things stop a door from closing: sunlight and frost. In the fall and winter, the low-angle sun can shine directly into a sensor’s “eye,” blinding it and preventing the door from closing. On cold, frosty mornings, condensation can fog the lens, which also blocks the beam. This is also the time spiders build webs in front of the lens. Before you call, always wipe the sensor lenses clean and check if direct sunlight is the culprit.

Frequently Asked Questions

Why does my garage door opener light blink 10 times?

This is a specific error code for LiftMaster, Chamberlain, and Craftsman openers. It means the safety sensors are misaligned, blocked, or faulty.

Why does my door reverse right when it hits the floor?

Your opener's "close travel limit" is set too far. It's programmed to go past the floor, so when it hits, it "thinks" it's an obstruction and reverses. This is a simple opener adjustment.

How do I bypass my garage door sensors to close the door?

You can temporarily bypass the sensors by pressing and holding the main wall button inside your garage. Do not let go until the door is fully on the ground. This should only be used to secure your door until a repair can be made.

Why won't my remotes close the door, but the wall button works?

First, check the "Lock" or "Vacation" button on your wall console. If that's not the issue, it could be a sign of faulty remotes or a problem with the opener's radio receiver.
