It's 9 p.m., the door is stuck open, and everything you own is on display. Work through this checklist in order. The fixes that are safe to try yourself, the two that never are, and how to secure the house if the door has to wait until morning.
Before the checklist: if at any point you find a broken spring (a visible gap in the coil above the door, or a bang you heard earlier) or a frayed or loose cable, stop there. Torsion springs are wound under enormous tension and cables are what keep that tension from letting go sideways. They injure people who work on them without the right tools and training, every year. Everything else on this page is safe to check yourself; springs and cables are a phone call.
1. Watch what the door actually does. Three different symptoms point three different directions: the door starts down then reverses (safety sensors), the opener hums or clicks but nothing moves (mechanical fault. Stop and call), or nothing happens at all (power or remote).
2. Check the photo-eye sensors, the #1 cause. Near the floor on both sides of the opening sit two small sensors facing each other. Both should show a steady indicator light. If one is dark or blinking: clear anything in the door's path, wipe both lenses with a dry cloth, and gently nudge the brackets until the lights go steady. A sensor knocked a few degrees by a trash can or a bike tire is the most common "broken door" in the metro, and the fix costs nothing.
3. Mind the Albuquerque specials. Two local patterns worth knowing. Low-angle sun: a photo-eye that faces the morning or evening sun can be blinded at the same time every day. If your door "breaks" on schedule, shade the sensor with your hand and try again; a small cardboard shade fixes it permanently. Spring winds: after a windy day, dust and debris in the tracks and across the sensor path cause exactly this failure. If the door won't close the evening after a dusty afternoon, clean the lenses and sight down both tracks before assuming worse.
4. Rule out the easy electronics. Try the wall button instead of the remote. If the wall button works, it's a remote battery or programming, not the door. Check that the opener's outlet has power (test it with a phone charger). And look for a "lock" or "vacation" switch on the wall console; a house guest pressing it is a classic.
5. Look at the tracks, don't force anything. With a flashlight, sight down each track for bent sections, debris, or rollers sitting out of the rail. A door that's visibly crooked or off its track should not be run again. Each attempt does more damage.
6. Close it manually, with care. If the opener is the problem and the door itself moves freely: pull the red emergency release cord (door fully down, or opening clear), and lower the door by hand. It should feel almost weightless. The springs do the lifting. If it's heavy, drop-prone, or fights you, let go carefully and stop: that weight means a spring or cable problem, and the door can fall. Once closed, most doors can be secured with the manual slide lock, or a padlock through a track hole just above a roller.
Sometimes the fault is found at 10 p.m. and the sensible move is a morning repair. Treat the open garage like an open front door until then:
A door stuck open is worth saying so when you call. Most companies, ours included, treat it as an emergency call rather than a next-available appointment.
Sensor realignment and the checks above are free if you do them yourself. If it goes beyond that, typical Albuquerque ranges are covered in our repair cost guide: most sensor, roller and adjustment calls land at the low end of the service-call range, springs and openers in the mid hundreds. Knowing the numbers before you call is how you judge any quote you're given, including ours.
Worth pinning inside the garage: reversing door = check the sensors · humming opener = stop and call · nothing at all = power, remote, lock switch · broken spring or cable = never DIY · stuck open = secure the house and say so when you call.
Almost always the safety sensors. If the photo-eyes near the floor are blocked, dirty, misaligned, or blinded by direct sun, the opener assumes something is under the door and reverses. Clean the lenses, clear the path, and check both indicator lights are steady.
Usually yes. Pull the red release cord and lower it by hand. It should feel light. If it's heavy, crooked, or slams, stop: that points to a broken spring or cable, and the door should only be moved by a technician.
Treat it as an open front door: lock the interior house door, move valuables out of sight, park a vehicle in or across the opening, unplug the opener, and get it repaired as soon as possible.
Low-angle desert sun can blind a photo-eye at the same time each day, and spring winds drive dust into the tracks and sensor path. Same-hour failures point to sun; after-a-windy-day failures point to dust.
