Garage Door Won't Open in Surprise, AZ

The opener does nothing: no light, no sound

This is the one group where a few free checks are worth doing first. Make sure the opener is plugged in and its outlet has power, and check the breaker. Look at the wall console: many have a lock button that stops the remotes from working, and it is easy to press by leaning something against it. If the wall button works but the remotes do not, the remote's battery or its pairing is the likely cause, and the summer power flickers here are known to wipe an opener's memory. If power is confirmed and nothing responds at all, it is an opener repair, and most of those run $100 to $220.

The motor runs or hums, but the door stays down

This is the pattern that most often means a broken torsion spring. The springs carry the weight of the door and the opener only guides it, so once a spring breaks the opener is asked to lift a door it was never built to raise. Without touching anything, look at the spring on the bar above the door: a clear gap in the coil means it has broken. People often remember a loud bang from the garage, sometimes at night as the temperature falls. The other causes in this group are inside the opener: a motor that runs while the chain or belt and the trolley stay still usually has a stripped drive gear, and a hum with no movement at all often means a failed start capacitor. Stop pressing the button in every case. What a broken spring costs to put right in Surprise is set out on the spring page.

The door rises a few inches, then stops

A door that lifts a hand's width and gives up is usually a spring that has lost most of its strength, even if it has not snapped yet. The opener senses the extra weight and quits, which is what it is designed to do. In this climate that often shows up late in summer, after the springs have weakened through June and the opener has strained through July. Turning up the opener's force to push past it hides the problem and wears out the opener.

The door is crooked, or a cable is hanging loose

If one side of the door sits higher than the other, a roller has left the track, or a lift cable hangs slack, do not run the door at all. A door in that state can drop. Keep everyone clear and leave the release cord alone unless the door is fully closed. This is off-track and cable work, which typically runs $150 to $350 depending on parts.

It opens in the morning but not in the afternoon

An opener that quits after several back-to-back runs on a hot afternoon, and comes back to life once it has cooled for a while, has usually tripped its thermal cutout. The motor unit sits up near the roof deck, the warmest spot in the garage, and in a West Valley summer that air runs well past the outdoor high. Let it cool. If it keeps happening, the heat page explains what that says about the unit's age.

Why it is so often the spring in Surprise

A torsion spring's rating is a count of cycles, typically around 10,000 openings and closings, and the builder-grade springs common in the big 2000s subdivisions here tend to fail at six to nine years rather than twelve or more. Surprise is full of houses at that stage or past it. By the American Community Survey's count, more than half of the city's roughly 62,100 homes date from the 2000 to 2009 building boom, and 13,617 more have been added since 2010 (Census Reporter, Surprise, 2020 to 2024 five-year estimates). On many streets a first spring failure is due now, or has already happened.

When it needs a technician

• Any broken or weak spring, on a torsion or an extension system.
• A loose, frayed or snapped cable, or a roller out of its track.
• A door hanging crooked or stuck part way.
• An opener that still does nothing after the power, the lock button and the remotes have been checked.

Springs and cables hold enough tension to cause serious injury, and they are never a job to learn on. This site lists $220 to $420 for a torsion spring pair, $200 to $280 for an extension spring pair, $100 to $220 for most opener repairs and $150 to $350 for typical off-track work. Requests made here are handed to one licensed garage door business in the West Valley, separate from this site, which quotes before starting and does the repair.
