Start by listening, not lifting
Press the wall button once and pay attention from a safe spot. Silence, a hum, a click, or a motor that runs while the door sits still each point somewhere different. That single test tells you more than any amount of tugging on the handle.
The cause we take most seriously is a broken spring. The springs carry the door’s weight; the opener only guides it up and down. With a spring gone, the opener strains against a dead weight, and the door may creep up a few inches and quit, or not move at all. If that is what you see, stop pressing the button and read about our spring repair.
If nothing happens at all, think power and settings first. If the motor runs and the door doesn’t budge, the door and the opener may have come apart at the trolley, or a gear inside the opener has worn down.
What the sound tells you when a garage door won’t open
Match what you hear to the list below. It won’t replace a look at the door, but it points you to the right next step.
- No light, no sound. The opener has probably lost power: a tripped breaker, a garage outlet whose reset button popped, a loose plug or an outage on your street.
- The opener light works, the remote doesn’t. The wall control may be in lock mode, or the remote battery is flat. If the wall button opens the door, the opener itself is fine.
- A hum or a strain, and little movement. Most often a broken spring, sometimes a cable that has come off its drum (the grooved wheel at each end of the spring bar). Stop and call.
- The motor runs, the door stays put. The trolley, the carriage that rides the opener rail, may be unhooked because someone pulled the red cord. Or the drive gear is stripped.
- A click and nothing else. Often a worn part inside the opener or a fault on its logic board, which is opener repair work.
- A thunk, and the door won’t budge. Some doors have a slide lock or a lock bar on the inside. If it’s engaged, the opener pulls against it.
A cable off its drum usually leaves the door hanging crooked, one side higher than the other. Treat that like a broken spring and leave it alone, because the parts around it are under tension.
What you can check without getting hurt
Look up before anything else. A torsion spring is the thick coil on the bar above the door, and a broken one shows a clear gap in the coil. On doors with extension springs, the springs run above the tracks on each side, and a snapped one may dangle from the safety cable threaded through it.
Next, power. See whether the opener light comes on, check the breaker panel, and press the reset button on the garage outlet if it has one. If the whole street is dark, see opening the door during an outage for the by-hand method.
Then the controls. Turn off lock mode at the wall control, try a fresh remote battery, and make sure no slide lock is engaged on the door itself.
The red release cord comes last, and only with the door fully down. Once it’s pulled, lift by hand only if the springs look whole. With a broken spring the door is far too heavy and can drop without warning.
Never lift a door with a broken spring
We understand the pressure: the car is inside and you need to leave. But with a broken spring, whoever lifts the door takes on the weight the spring was holding, and it can slam down the moment a grip slips. A ladder or a board wedged underneath can kick out.
Don’t keep pressing the opener button either. Each try strains the motor, the gear and the trolley, and it can pull the door out of its tracks. One press tells you what you need to know.
If a car is stuck inside, say so on the phone, and we’ll tell you when we can come.
How the repair goes once you call
Call when you see a gap in a spring, a loose cable or a crooked door, or when the motor runs and nothing moves. Call too if the power is back and the opener still does nothing.
We find the cause before we fix anything. For a broken spring, that means fitting springs sized for the door and getting its balance right. For the opener, we test the power, the controls and the drive, then repair what failed; opener repair has the details. Before we leave, the door runs up and down several times and the auto-reverse is tested.
