Short answer
If your garage door opener is not working, first check that it has power. Look at the plug in the ceiling outlet, the garage breaker and any GFCI outlet in the garage. Then look at the wall control. If its lock light is on, hold the lock button until it turns off. Before you try again, look up at the springs: a gap in a spring means stop and call.
Safety first
Use a sturdy step ladder to reach the plug, never a chair. If a spring above the door has a gap, do not run the opener or lift the door: call a garage door company.
What to check when the opener does nothing
1You press the button and nothing happens
No hum, no light, no movement. Most of the time it is the power, the lock button or the remote. Start with the easy checks.
Read all the steps
- You press the button and nothing happens. No hum, no light, no movement. Most of the time it is the power, the lock button or the remote. Start with the easy checks.
- Make sure the opener has power. Push the plug firmly into the ceiling outlet. Still no light on the opener? Reset the garage GFCI outlet or the breaker, standing on a dry floor.
- Turn off the lock on the wall control. If a small light blinks on the wall control, the lock (vacation) mode is on. Hold the lock button for a few seconds until it stops.
- Look up at the springs before trying again. Each spring above the door should be one solid coil. A gap means a broken spring: do not run the opener, and call a garage door company.
- Press the wall button again. If the door opens, test the remote too. Still nothing, or the motor runs without moving the door? See the list below.
- Still not fixed? Call a garage door company Especially if: the opener has power but does nothing at all.

Other quick checks
- Only the remote fails? Change its battery. If the wall button works, the opener is fine.
- The motor runs but the door stays put? Someone may have pulled the emergency release cord, which disconnects the door.
- The door starts down and goes back up? Check the safety sensors near the floor.
- The opener light works but the wall control does nothing? The thin wire to the wall control may be loose or cut.
What not to do
- Do not keep pressing the button if the motor hums and the door does not move. It strains the motor and the gears.
- Do not open the motor cover or touch the wiring inside.
- Do not lift the door by hand if a spring or a cable looks broken.
When to call a garage door technician
- The opener has power but does nothing at all.
- The motor hums or clicks, but the door does not move.
- A spring has a gap or a cable hangs loose.
- You smell burning or see smoke near the motor.
Frequently asked questions
Why is my garage door opener not working?
Most often it has no power, the lock mode on the wall control is on, or the remote battery is dead. A broken spring, a pulled emergency release or a worn-out motor are the next suspects.
How do I reset my garage door opener?
Unplug it for about a minute and plug it back in. That clears many glitches. If it still does nothing, check the breaker and the GFCI outlets in the garage.
What does the lock button on a garage door opener do?
It blocks the remotes and the outdoor keypad, so nobody can open the door from outside. The wall button still works. A blinking light on the wall control usually means the lock is on.
Why does the opener light work but the door won’t open?
The opener has power, so check the lock mode, the emergency release and the springs. If those are fine, a gear or the circuit board may have failed. Call a technician.
Is it worth repairing a garage door opener?
Often yes, when it is a common part like the gear, the sensors or the wall control. If the opener is old and keeps failing, ask for a quote for both the repair and a new one.
Can a power outage break a garage door opener?
A power surge can damage its circuit board. If the opener stays dead after the power comes back, check the breaker and the GFCI outlets, then call a technician.
