What would cause a garage door opener to stop working?
Most opener calls start with one of six symptoms. Each one points at a short list of parts, which is why describing it on the phone saves a lot of guessing once we're in the garage.
Opens, won't close
Almost always the safety sensors: a bumped bracket, a dirty lens, a cut wire, or low sun shining straight into the receiver.
Motor hums, door sits
On LiftMaster and Chamberlain chain and belt units this is usually the nylon drive gear with its teeth worn off.
Lights keep blinking
That is a diagnostic code. Ten flashes on a LiftMaster or Chamberlain means the sensors, not the motor.
Remote went dead
Battery first. Then check whether lock mode got switched on at the wall button. After that it is programming or the receiver.
Reverses halfway down
Force or travel limits drifted, or a roller is binding in the track and the opener reads it as an obstruction.
No sensors at all
An opener with no photo eyes predates 1993. It can't be made safe by repair, so replacement is the honest answer.
Why call us
Opener repair that starts with the springs
An opener only steers the door. The springs carry its weight. So before we touch the motor we check balance, because a weak spring is the most common reason an opener strains, strips its gear and dies early.
- Door balance checked first
- Gear kits and logic boards
- Sensors realigned and rewired
- Reversal test before we leave
- Repair or replace, explained plainly
- Calls answered 7am to 10pm
Replacing an opener?
Chain, belt, screw or wall-mount
If the old unit isn't worth fixing, the drive type is the main choice. It decides noise, headroom and what the opener can lift.
| Drive | How it moves | Noise | Mounting | Best for |
|---|---|---|---|---|
| Chain drive | A steel chain pulls the trolley along the rail | Loudest | Ceiling rail | Heavy doors that cycle many times a day |
| Belt drive | A steel-reinforced rubber belt, no metal on metal in the rail | Very quiet | Ceiling rail | Garages under or beside a bedroom |
| Screw drive | A threaded steel rod turns and drives the carriage | Moderate | Ceiling rail | Owners who want few wearing parts |
| Wall-mount (jackshaft) | Mounts beside the door and turns the torsion shaft directly | Quiet | Side wall, no ceiling rail | Low ceilings, storage racks, torsion-spring doors only |
Openers on the leeward side
Why do openers act up in Kapolei?
Mostly for three reasons, and only one of them is the motor. The first is sun. Kapolei sits on the dry leeward side, and late-afternoon light coming straight down a west-facing driveway can blind the sensor receiver, so the door refuses to close until the sun drops. The second is salt. Near Ko Olina, Barbers Point and the Ewa shoreline, sea air rusts steel rail hardware, sensor brackets and the springs the opener depends on. The third is age. A stripped gear or a tired logic board is a routine fix on most LiftMaster, Chamberlain and Genie units, and we tell you when replacing the opener makes more sense.

How a repair goes
From the first call to a door that closes
1
Describe it
Call or send the form with the brand, roughly how old it is, and what it does. Blinks, hums and clicks all help.
2
Diagnose
We check spring balance, sensors, gear, board and limits, then give you a written price for the repair before any work starts.
3
Schedule
Pick a time that suits you. If a part has to be ordered for your model, you'll know that before anything is taken apart.
4
Test
After the repair we run the reversal test with a board on the floor and show you the sensors and the emergency release.

Opener problems
Start with the safety sensors, because nine times out of ten they're the cause. If the two photo eyes at the bottom of the tracks can't see each other, the door won't close. Clean the lenses, check both lights are steady, and look for a bumped bracket. Strong low sun can do it too.
Either the trolley is disengaged, which the red release cord does, or the drive gear inside the motor head is stripped. On most LiftMaster and Chamberlain chain and belt units the gear is nylon, and replacing it with a gear kit is a standard repair.
LiftMaster, Chamberlain, Craftsman, Genie, Linear and Marantec cover most garages on the west side. LiftMaster and Chamberlain are the same company, so many parts match. Genie belongs to the Overhead Door group. If you're unsure of the brand, read us the label on the motor head.
On most LiftMaster and Chamberlain units, press and hold the learn button on the motor head until its light goes out, about six seconds. That erases every paired remote and keypad, so you'll need to program the ones you keep again. Unplugging the opener doesn't clear them.
Often, yes. A gear kit, sensor set or remote is a small fix on a sound unit. Replace instead when the opener has no photo eyes, which means it predates 1993, when the logic board for that model is no longer made, or when repairs keep stacking up.

Remotes, smart and booking
Most openers have a learn button on the motor head, near the light lens or under a cover. Press it, then press and hold the remote button until the opener light flashes or you hear a click. Steps vary by model and year, so we can do it during any visit.
In late 2023 Chamberlain Group blocked unofficial third-party access to myQ, which cut off integrations like Home Assistant and Homebridge. The myQ app itself still works, as do paid partners such as Ring and Alarm.com. If you want other control, a separate controller can be added.
That's normal on LiftMaster and Chamberlain units: the sending eye shows amber and the receiving eye shows green. Trouble is when one light is off or blinking. That means the beam isn't reaching, usually from a knocked bracket, a dirty lens, a loose wire or sun hitting the receiver.
Every day from 7am to 10pm. Call or text the number at the top of the page, or send the form and we'll call you back. A door stuck open at night is a security problem, so tell us if that's the situation.
No. Straining usually means the springs aren't carrying the door's weight anymore, and the opener is doing a job it wasn't built for. Running it that way strips the gear. Close the door, leave it, and call. Don't pull the release cord on an open door.
