Why Your Garage Door Will Not Open

By the Tempe Garage Door Service team · Updated September 2026

Start With What the Opener Is Doing

The single most useful observation is whether the motor runs. Stand where you can hear it and press the button once. If there is no sound at all, no lights and no click, you have a power or control problem. If the motor runs but nothing moves, the drive or the door is at fault. If the motor strains, lifts the door a few inches and stops, the springs are the first suspect.

Press the button once, not repeatedly. Every extra attempt against a jammed or unbalanced door risks bending a track, stripping a gear or pulling a cable off its drum. One attempt tells you everything a dozen would.

The Power and Control Checks

If nothing happens at all, look at the outlet. Openers are usually plugged into a ceiling receptacle that shares a circuit with the garage lights, and a tripped breaker or a receptacle knocked loose during a tidy-up is more common than people expect. Check whether the garage lights work.

If the wall control works but the remotes do not, the problem is almost certainly the remotes rather than the opener. Batteries are the first thing to change, and heat in an Arizona garage does shorten their life. If a keypad outside has stopped responding but everything indoors works, that is also a control problem rather than a door problem.

Some openers have a vacation or lock mode on the wall console that disables the remotes deliberately. It is worth glancing at, because it looks exactly like a receiver failure.

When the Springs Have Failed

If the opener runs hard, the door lifts a few inches and it stops or reverses, stop and look above the opening. A torsion spring that has broken will usually show a clear gap in the coil. You may also have heard a loud bang from the garage earlier, often overnight, which is the moment it let go.

Do not try to lift the door by hand to test this. Without its spring the door carries its full weight, and it can come down hard. Do not pull the red release cord while the door is part-way up either, because releasing the trolley on an unsupported door lets it drop. Leave it where it is.

When Something Is Jammed

A door that stops at an odd angle, sits higher on one side or grinds as it moves is a mechanical problem rather than an electrical one. Look for a cable that has come off its drum, a roller sitting outside the track or an obvious obstruction under the door. A dent in the track from a bumper will stop a door dead in the same spot every time.

Again, this is a look-and-report situation, not a fix-it-yourself one. An off-track door is still connected to springs under tension, and levering it can release that load without warning.

The Sensor Question

Safety sensors stop a door closing, not opening, so if your problem is purely that the door will not go up, the sensors are not the cause. They are worth knowing about anyway, because a door that opens fine but refuses to stay closed is nearly always a sensor alignment issue. The opener troubleshooting guide works through that in order.

Doors That Will Not Open in Tempe

Two seasonal patterns turn up here. The first is the summer failure: a garage that has been sitting above 120 degrees for weeks is hard on opener boards, capacitors and remote batteries, and heat is the most common reason a door that worked in spring stops in July. The second is the return of a seasonal resident to a house that has been closed up, where the rollers have dried out and the opener did not survive the summer.

Monsoon storms add a third. Strong straight-line winds and blown dust can shift a lightly built door in its tracks and pack grit into the roller bearings. If yours stopped working the day after a storm, mention that when you call. In the older parts of the city east of Tempe the pattern is slightly different again, and garage door repair in Mesa covers what tends to fail on those doors.

What to Tell the Technician

Four things make a visit far more efficient. Whether the motor runs. Whether you heard a bang. What position the door stopped in. Whether a car is shut inside. If you can find the model label on a door section or the side of the motor housing, that helps too, because it determines which parts fit.

Leave the door closed and keep people and vehicles out from under the opening while you wait. If the door is stuck open and the garage cannot be secured, say so, because that changes how the call is prioritized.

Arrange an Inspection

A door that will not open is nearly always a defined mechanical or electrical fault rather than a mystery. Tempe Garage Door Service can identify it and quote the repair before starting, whether that turns out to be spring repair, opener repair or something in the lifting hardware. Send the symptoms through the service request page and keep clear of the door until it has been looked at.
