Garage Door Won’t Open? What to Check and When to Call

Reviewed and updated: 14 October 2026

You’ve pressed the remote, nothing useful has happened, and the car is on the wrong side of the door. Before you press it again, stop and take note of what the door is doing. What you can safely see and hear provides useful clues, but similar symptoms can have different causes.

What to check first when a garage door won’t open

Start with the case where nothing happens at all. No hum and no light on the opener. Power or controls may be involved. Limit your checks to ordinary, safely accessible owner controls; do not open electrical housings or climb into the door mechanism.

Look at the power point, which is normally on the ceiling or high on the wall near the motor. From the ground, look for an obvious power interruption. Check a plug or switch only if it is safely accessible without a ladder or reaching near the door hardware. Then look at the switchboard for a tripped circuit breaker or safety switch.

If the opener has power, try the wall button. If the door opens from the wall but not from the remote, the handset, its battery or its programming may need checking. A weak one usually loses range for a while before it gives up.

The other cause catches people after a trip away. Many wall controls have a lock or holiday mode that switches the remotes off so the door can’t be opened while you’re gone. If someone has bumped that button, the remotes go dead while the wall control carries on working. The opener’s manual will show how to turn it off for your model.

The motor runs but the door stays put

You can hear the opener working, and you might see the chain or belt travelling along the rail, but the door doesn’t move.

One possibility is that the manual release has been operated; a technician may need to rule out other faults. On a sectional or tilt door that’s the cord with a handle, usually red, hanging from the trolley on the overhead rail. On many roller door openers it’s a cord or lever at the motor itself. It’s there so you can work the door by hand in a blackout, and once it’s pulled the motor is disconnected from the door. Kids pull them, and a ladder or roof rack can catch the cord.

Putting it back into gear is usually a small job and the manual will show the method for your opener, but do it with the door fully closed. If the door is partly open and you’re not certain the springs are sound, leave it and ring us. A disengaged door with a failed spring can come down fast.

The door feels very heavy, stops short or hangs crooked

The door rises 10 or 20 centimetres, the motor strains, and it stops or goes back down. Or you’ve pulled the release and found you can’t budge it. A spring or another part of the door system may be involved. Stop using it and arrange assessment rather than testing it by hand.

The springs counterbalance the door’s weight, while a correctly matched opener moves the properly balanced system. On a sectional door the torsion spring is the heavy coil on a steel shaft across the top of the opening. A broken one shows a clear gap in the coil, where it used to be one continuous spring. Tilt doors often have long springs at the sides. Roller door springs sit inside the drum, so you won’t see those at all.

People often hear it go. A single loud bang from the garage, sometimes hours earlier or overnight, that gets blamed on something falling off a shelf.

Without the spring, the opener is trying to lift the full weight of the door, and the load may be far beyond normal operating conditions. Springs are wound under heavy tension, and fitting a new one means loading that tension back on with the proper tools and a spring matched to the door’s weight. That makes garage door spring replacement a technician’s job.

A door that sits higher on one side, or has jammed on an angle in the tracks, may have a cable, track or other mechanical fault. Lift cables are thin steel wire ropes running from a bracket at each bottom corner of the door up to a drum at each end of the spring shaft. If one frays through or jumps off its drum, that side drops while the other keeps lifting. You might see a loose loop of cable hanging beside the track, or a tangle of wire at the drum.

Stop the door where it is. Running the opener again can twist the panels and pull the rollers out of the tracks, which turns a garage door cable repair into a much bigger job.

What not to do with a stuck door

• Don’t keep pressing the remote. Each attempt loads up the motor and whatever has broken.
• Don’t try to lift the door by hand.
• Don’t touch the springs, cables, drums or bottom brackets.
• Don’t stand or park under a door that is stuck part way open.
