What It Means When Your Opener Hums but the Door Will Not Open
The motor is getting power, but something stops it from lifting the door. The problem is either inside the opener or in the door itself.
A worn gear or a failed capacitor is inside the opener. A broken spring or a locked door is in the door. The spring is the most serious, so check for it first.

Most likely causes
- A stripped drive gear
- A failed capacitor
- A broken spring
- A locked door
- A door disconnected from the opener
- A door binding in its tracks
Six Causes of a Humming Opener
From least to most serious to the door. A technician confirms which one you have.
Stripped drive gear
The gear inside many openers wears out. The motor spins, but the drive does not turn. It is the classic failure on older chain drive openers.
Failed capacitor
The capacitor helps the motor start. When it fails, the motor hums without turning.
Broken spring
A broken spring makes the door too heavy to lift. Signs are a loud bang, a gap in the spring coil, or a crooked door. This is the most serious cause.
Locked door
A manual slide lock or handle lock holds the door to the track, and the opener strains against it.
Disconnected door
If the release cord was pulled or the door arm came loose, the motor can run without moving the door. Ryobi lists this as a cause when the opener runs but the door stays put.
Door binding in the tracks
Bent tracks or a door off its rollers stop the door and strain the opener.
What You Can Safely Check
No tools needed. Stop at the first sign of a spring problem.
Safe steps
- Stop pressing the button. Repeated tries can burn out the motor.
- Check the door locks. Release any slide lock or handle lock on the door.
- Look for a spring problem. A loud bang, a gap in a spring, slack cables, or a crooked door means stop.
- Watch the rail. Press the button once. If the trolley moves but the door does not, the door is disconnected. If nothing moves and the motor hums, think gear or capacitor.
Do not
Do not pull the red release cord if the door is open, partly open, or you suspect a broken spring, because the door can fall fast. Do not touch springs, cables, or the brackets at the bottom corners. DASMA says they are under extreme tension. See our emergency repair page if the door is stuck.

Why Openers Hum in Las Vegas
Heat
Las Vegas hit 120 degrees on July 7, 2024, according to the National Weather Service. Heat wears on motors, capacitors, and circuit boards.
Power surges
Monsoon storms run from late June into September. A surge can damage the capacitor or board.
Age and wear
Gears and capacitors wear out. Many openers last 10 to 15 years, according to House Digest.

Humming Opener Questions in Las Vegas
Why does my garage door opener hum but not open the door?
A hum means the motor has power but cannot move the door. The cause is either inside the opener, such as a stripped gear or a failed capacitor, or in the door, such as a broken spring or a locked door.
Is a humming opener a stripped gear?
Often, if nothing moves on the rail while the motor hums. A stripped drive gear is a classic cause, especially on older chain drive openers. A technician confirms it.
Can a bad capacitor make an opener hum?
Yes. The capacitor helps the motor start. When it fails, the motor can hum without turning.
Could a broken spring make my opener hum?
Yes. A broken spring makes the door too heavy to lift, so the motor hums and strains. Signs are a loud bang, a gap in the spring, or a heavy door. Stay clear and call us.
Should I keep pressing the button?
No. Repeated tries strain the motor and can burn it out. Stop, and check the safe items on this page.
Can I open the door by hand when the opener hums?
Only if the door is fully closed and you are sure a spring has not broken. Pull the red release cord and lift slowly. If the door feels heavy, stop and call us.
How much does it cost to fix a humming opener?
It depends on the part that failed. A gear or capacitor costs less than a new motor, and a spring problem is a separate repair. You get the total before work starts. Our repair cost guide explains what changes the price.
Should I repair or replace a humming opener?
Repair often makes sense for a newer opener with one failed part, such as a gear or capacitor. If the opener is past 15 years or keeps failing, replacement may make more sense.
Is a humming opener an emergency?
It is if the door is stuck open 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.
Do you repair all opener brands?
We repair LiftMaster, Chamberlain, Genie, and Craftsman openers, and other supported brands.
