Why Your Opener Reverses: It Thinks Something Is in the Way

Every opener must reverse a closing door that touches an object. The CPSC requires it, and the door must reverse within two seconds. So a reverse with an object in the way is a good sign.

A reverse with nothing in the way means the opener is misreading the door. It may feel the floor, a binding track, or a blocked sensor as an obstruction. Where the door reverses tells you the likely cause.

Where does it reverse?

At the floor: the down travel may be set too far
A few inches above the floor: the force may be too sensitive, or something is under the door
Partway down: a blocked sensor or something in the doorway
With scraping or grinding: a binding track or rollers

Six Causes of an Opener That Reverses

Start with where the door reverses.

Down travel set too far

The door presses into the floor, and the opener treats it as an obstruction. Chamberlain says this is the most common reason a door reverses after it touches the floor.

Force too sensitive

If the close force is too low, normal resistance near the floor can trip the reverse.

Blocked or misaligned photo eyes

Dust, a stored item, or a bumped sensor can interrupt the beam. Both sensor lights should glow steady.

Something under the door

Debris, a stone, or a bent bottom seal can catch under the door as it closes.

Door out of balance

A weak or broken spring makes the door heavy, and the extra resistance can trip the reverse. This is the most serious cause.

Binding track or worn rollers

Bent tracks or worn rollers drag on the door and add resistance.

What You Can Safely Check

No tools needed. Stay clear of the door while you test, and stop at the first sign of a spring problem.

Safe steps

Clear the floor under the door. Remove stones, debris, and anything in the beam path.
Check both sensor lights. Both should glow steady. Wipe the lenses.
Watch where it reverses. Note whether it is at the floor, just above it, or partway down.
Look at the bottom seal. See whether it folds or catches as the door closes.
Run the 2 by 4 test. Lay a 2 by 4 flat under the door and press close. The door should touch it and reverse.

Do not

Do not tape over a sensor or turn the force up to stop the reverse. That can disable the safety reverse. Do not touch springs, cables, or the bottom brackets. DASMA says they are under extreme tension. If the door feels heavy, stop and call us.

Reverses and the door feels heavy	A weak or broken spring	Stay clear of the door	Always, and it is urgent

Why Openers Reverse in Las Vegas

Dust and debris

Dust builds up fast in the Valley. It can block sensor lenses and gather under the door. 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. Parts wear over time. Many openers last 10 to 15 years, according to House Digest.

Reversing Opener Questions in Las Vegas

Why does my garage door opener reverse before closing?

The opener thinks something is in the way. Common causes are blocked or misaligned photo eyes, a down limit set too far, a force setting that is too sensitive, and a door that binds in the tracks.

Why does my door hit the floor and go back up?

Chamberlain says the most common reason is that the down travel needs adjusting, so the opener feels the floor as an obstruction. Other causes are a door problem or, rarely, the logic board.

Why do my opener lights flash five times when the door reverses?

On Chamberlain Security+ 2.0 openers, five flashes and a beep mean the door touched an obstruction while closing, according to Chamberlain. Other brands use different codes, so check your manual.

Is a reversing door a safety feature?

Yes. A closing door must reverse within two seconds of touching an object, according to the CPSC. A reverse that works is good. A reverse with nothing in the way needs a fix.

Can I turn up the force to stop it from reversing?

Not without testing. Raising the force or moving a limit can disable the safety reverse. Test with a 2 by 4 after any change, or call us.

How do I test the safety reverse?

Lay a 2 by 4 flat under the door and press close. The door should touch it and reverse. Test it each month. If it fails, stop using the opener and call us.

Can a broken spring make my door reverse?

Yes. A door that is out of balance adds resistance, so the opener can reverse. Signs are a heavy door, a loud bang, or a gap in the spring. Stay clear and call us.

Is a reversing door 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 a reversing opener?

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

Do you repair all opener brands?

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