Garage Door Won’t Open? What to Check First

When your garage door won’t open, the cause is usually one of five things: power, the lock, the release cord, a broken spring or the opener itself. Some take a minute to fix. One of them, a broken spring, makes the door dangerous to touch. This guide helps you tell them apart in the right order.

First, notice what happens when you press the button. Does nothing happen at all? Does the motor run but the door stay put? Or does the door lift a few inches and stop? Each one points somewhere different.

If nothing happens at all

Check the power first. Look at the opener on the ceiling. If its light does not come on, the opener may be unplugged or the circuit may be off. Garage outlets often sit on a GFCI outlet that can trip during a storm. Press its reset button, then check the breaker panel.

Next, check the lock. Many wall controls have a lock or vacation button that blocks every remote and keypad. Does the wall button work but not the remote? Then our guide to a garage door keypad or remote not working covers the fixes.

If the motor runs but the door does not move

The most common reason is simple. Someone pulled the red release cord, and the opener is no longer connected to the door. The trolley just slides along the rail. The fix is to reconnect it. Our guide on how to manually open a garage door explains how for each rail type.

If the opener is connected and still the garage door won’t open, look up at the springs. A torsion spring with a gap in the coil is broken. Without it, the door is far too heavy for the motor. DASMA, the door industry’s trade group, says spring systems should be repaired only by trained professionals.

A grinding or whirring sound with no movement can also mean a worn gear inside the opener. That needs opener repair, not more button presses.

If the door lifts a little, then stops

A door that rises a few inches and stops is usually too heavy or blocked. A broken or weak spring is the top suspect. A frayed cable, a bent track or a roller out of its track can also stop it.

Do not keep pressing the button. Each try strains the motor and can bend the top section of the door. Close the door if it will close, and call for help. A door hanging crooked needs off track repair.

Check the manual lock and the tracks

Some doors have a slide lock on the inside. If someone locked it, the opener will strain and may reverse. Slide the bar out of the track and try again.

Then look along both tracks for anything in the way. A tool, a bike wheel or a loose bracket can jam a roller. Remove the object, but do not loosen any bolts on the tracks or brackets yourself.

When your car is stuck inside

A door that will not open with the car inside feels urgent. Still, never try to lift a door with a broken spring. And never pull the release cord on a door that is open or crooked. It can drop fast.
