Describe the Problem

Why Your Opener Won’t Close: Start With the Photo Eyes

The two photo eyes sit near the floor on each side of the door. They send a beam across the doorway. If something blocks the beam, the opener will not close, or it closes and then reverses.

That is a safety feature, so a blocked, dirty, or misaligned sensor is the most common cause. Lock mode, sensor wires, and the limit settings are the next things to check.

Fast answers

Lights flash and the door will not close: check the photo eyes and the Lock button
Door closes only while you hold the wall button: a sensor problem
Door goes down, then back up: something is blocking the beam or the limits are off
Remote fails but the wall button closes it: check the remote and lock mode

Six Causes of an Opener That Won’t Close

Start at the top. The first three cause most cases.

Blocked or dirty photo eyes

Dust, a stored item, or a leaf can block the beam. Wipe both lenses and clear the floor near them.

Misaligned photo eyes

A bump can knock a sensor out of line. Both lights should glow steady. A light that is off or blinking means a problem.

Sunlight on a sensor

Bright sun shining into a lens can interrupt the beam on some setups.

Damaged sensor wiring

A cut or loose wire stops the sensor signal, so the lights may stay off.

Lock mode is on

With lock mode on, the opener ignores remotes. Chamberlain says two flashes of the opener light mean the Lock button is on.

Limit or force settings

If the limits are off or the force is too sensitive, the door can reverse on the way down.

What You Can Safely Check

No tools needed. Stay clear of the door while you test.

Safe steps

Clear the doorway and the floor near the sensors. Remove anything in the beam path.
Look at both sensor lights. Both should glow steady. A light that is off or blinking means a blocked, dirty, or misaligned sensor.
Wipe the lenses with a dry cloth.
Check the Lock button on the wall control. Turn lock mode off.
Test once. Press close from a spot where you can see the door, and stay out of its path.

Do not

Do not tape over a sensor, block it, or hold the wall button to force the door down as a habit. That bypasses the safety sensors. Chamberlain notes that openers made after February 3, 2022 no longer close this way. Do not touch springs or cables. DASMA says they are under extreme tension.

Why Openers Won’t Close in Las Vegas

Dust

Dust builds up fast in the Valley and can block a sensor lens. Wipe the lenses each month.

Storms and surges

Monsoon storms run from late June into September. A surge can damage the circuit board or sensor wiring.

Heat and age

Las Vegas hit 120 degrees on July 7, 2024, according to the National Weather Service. Wiring and sensors wear over time. Many openers last 10 to 15 years, according to House Digest.

Opener Won’t Close Questions in Las Vegas

Why won’t my garage door opener close?

The most common cause is a blocked, dirty, or misaligned photo eye. Other causes are lock mode, damaged sensor wires, limit or force settings, and a door that binds.

Why do my opener lights flash and the door won’t close?

On Chamberlain openers, ten flashes point to a sensor problem and two flashes mean the Lock button is on, according to Chamberlain. Other brands use different codes, so check your manual.

Why does my door close only when I hold the button?

That points to a sensor problem, because holding the button bypasses the photo eyes. Do not rely on it. Chamberlain says openers made after February 3, 2022 no longer have this feature.

Why does my door go down and then back up?

The opener may sense something in the doorway, a blocked or misaligned sensor, or a limit or force setting that is off. Do not bypass the sensors. Clear the doorway and check the sensor lights.

Can sunlight stop my door from closing?

It can. Bright sun shining into a sensor lens can interrupt the beam on some setups. Shading the lens may help, or call us.

How do I align my photo eyes?

The two sensors face each other near the floor on each side of the door. Ease the bracket just enough to move the sensor, point it at the other one, and tighten when both lights glow steady. If it will not hold, call us.

Is a door that won’t close an emergency?

It is if the door is stuck open and you cannot secure the garage, or your car is trapped inside. Emergency service is available 24/7 and costs a little more than a regular visit. See our emergency repair page.

How much does it cost to fix an opener that won’t close?

It depends on the cause. Cleaning and aligning sensors usually costs less than replacing a sensor, a wire, or a board. You get the total before work starts. Our repair cost guide explains what changes the price.

Should I replace the photo eyes?

If cleaning and aligning do not work, a damaged sensor or wire may need replacing. We test them and replace what failed.

Do you repair all opener brands?

We repair LiftMaster, Chamberlain, Genie, and Craftsman openers, and other supported brands.
