Garage Door Won't Open? Here's the Order to Check Things

Why a garage door won't open, checked in the order that actually finds the problem: dead spring, failed opener, blocked sensor, or a jammed track, from the company that fixes them same day in the Phoenix Valley.

Nine times out of ten it is one of three things, and you can usually tell which before you even call anyone. A dead spring makes the whole door feel bolted to the floor. A dead opener means the motor runs, or does nothing, while the door stays put. A blocked sensor means the door starts to close and reverses, or never gets the signal to move at all.

Start With the Sensors, Not the Motor

Before you touch a wrench, look at the two small boxes near the floor on each side of the track. A steady light on both means they are aligned and seeing each other; a blinking or dark light means one of them is knocked out of position, dirty, or sitting in direct morning sun. This alone accounts for a large share of the 'won't open' calls we get, and it costs nothing to check. Wipe both lenses with a dry cloth and nudge the bracket until the light goes solid.

The Two-Hand Test: Spring or Opener?

Pull the red release cord so the opener disconnects from the door, then lift the door by hand a few inches. If it feels like dead weight and barely moves, the spring has let go and the opener was never the problem, it just could not lift a door with no spring tension left. If the door lifts smoothly on its own and stays where you leave it, the spring is fine and the fault is in the opener or its wiring.

The Opener Hums But the Door Doesn't Move

A hum with no movement is usually a dying capacitor or a stripped drive gear, not the motor itself. Running it repeatedly on a stripped gear turns a 200 dollar gear kit into a full motor replacement, so it is worth stopping after the first hum rather than trying it five more times.

The Door Won't Budge Even by Hand

If the manual lift test does not move the door at all, check for a bent track pinching a roller, or a manual lock slide engaged at the bottom corner, before assuming the worst. Both are common after someone tries to force a stuck door and end up needing a technician anyway, just for a different reason than they started with.

Other Reasons It Won't Open

The remote's battery died and the wall button also stopped working, which usually points to a tripped breaker or a GFCI outlet the opener is plugged into.
The keypad code was reset during a power blip and needs to be reprogrammed.
Someone pulled the manual release handle to move the door by hand and never reconnected it to the opener carriage.
A slide lock or padlock bar at the bottom of the door is engaged from the inside.
The track has a bend or dent, usually from a car bumper or a ladder, pinching a roller at one spot.

What It Costs to Fix

If it is the spring, a same day replacement runs 180 to 290 dollars depending on the size and cycle rating, the same price whether it is a Tuesday afternoon or a Saturday morning. The 35 dollar service call comes off that if the repair goes ahead. Opener repairs and sensor realignments are usually on the lower end of that range, and we give you the number on the phone before anyone drives out.

When It's More Than a Quick Fix

Both springs are old enough that the second one is close behind the first, which is why they are changed as a pair.
The opener motor itself has burned out, not just the gear or capacitor.
A cable snapped at the same time the spring did, which is common since they share the load.
The track bent enough from forcing the door that it needs replacing, not just realigning.

Anything else on this list and it is still a same day fix. We carry springs, gears, and sensors for the openers used across the Valley, which is why most of these finish on the first visit.

Answers

Questions People Ask About This

Why won't my garage door open with the remote but the light comes on?

The light coming on means the opener has power, so the fault is almost always the sensors or the remote itself, not the motor. Check that both sensor lights are solid, then try the wall button. If the wall button also does nothing, the fault has moved from the remote to the opener's wiring or a tripped breaker.

Is it safe to force a stuck garage door open by hand?

Only if you've disconnected the opener first by pulling the red release cord. Forcing a door that is still connected to the opener can strip the drive gear, and forcing a door with a broken spring can let it drop suddenly. If the door won't move even with the opener disconnected, stop and call rather than keep pulling on it.

Why does my garage door opener hum but the door won't move?

A hum with no movement is almost always a failing capacitor or a stripped internal gear, not a dead motor. Both are common once an opener passes eight to ten years old in Arizona heat. Running the opener repeatedly once you hear the hum is what turns a gear repair into a full motor replacement.

How much does it cost if my garage door won't open because of a broken spring?

A same day spring replacement runs 180 to 290 dollars depending on the spring size and cycle rating, with the 35 dollar service call coming off that total if the repair goes ahead. We give you the exact number over the phone before anyone is booked, and it does not change for a same day appointment.
