Garage door opener repair and installs in San Diego
Most dead openers need one part, not a whole new unit. I carry gears, sensors and remotes on the truck, special-order logic boards, and install LiftMaster when replacing makes more sense.

Opener humming, blinking or doing nothing?
Garage door opener repair in San Diego is the second thing I get called for most, right behind springs. If the motor hums and the door sits there, the light blinks and the door won't go down, or the remote quit and the wall button still works, tell me what it's doing when you call (619) 930-7869. Those three symptoms point at three different parts.
Before I blame the opener, I check the door. An opener is built to guide a balanced door, not to lift dead weight. If a spring is broken or a roller is jammed, a brand-new motor would fail the same way, so I fix the cause first and the opener second.
What is it doing?
Pick the closest one, or just describe it on the phone.Motor hums but the door doesn't move
Often a stripped drive gear or a broken trolley. Sometimes the door is the problem, not the motor.
Light blinks and the door won't close
The safety sensors can't see each other. Knocked out of line, dirty lenses or a cut wire.
Remote or keypad stopped working
A battery, a lost code or a failing receiver. Usually a quick fix on the first visit.
Door starts down then reverses
Force or travel limits have drifted, or the door is binding and the opener is protecting itself.
Louder than it used to be
Worn sprocket, loose chain or a dry rail. Belt drives are much quieter if it's time to replace.
Dead after a power outage
Tripped outlet, a blown board or a battery backup that's past its life. I check all three.
What I check first
- 1
Diagnose
I pull the release and lift the door by hand. If it's heavy or drifts, the springs come first. Then the gear, trolley, sensors, limits, board, outlet and remotes, in that order.

Explain
I show you the part that failed, tell you whether repairing it makes sense for the age of your unit, and give you the price before I start. If it's close, you get both prices.

Repair
Part from the truck, limits and force reset, sensors aligned, remotes and keypad programmed, then I run the door with you watching and test the auto-reverse.
What I fix and install
Repairs on most residential brands. New installs are LiftMaster, or Marantec when the space is tight.Gears
The usual cause of a hum with no movement on chain and belt units.
Safety sensors and wiring
Aligned, cleaned or replaced, and the wire run checked for staples and pinches.
Logic boards and receivers
Special order. There are too many boards to carry, so I order the one for your model, if it's still made.
Remotes and keypads
Programmed or replaced, including car buttons when your vehicle supports it.
New LiftMaster openers
Chain or belt drive with battery backup and Wi-Fi. Heavy-duty and side-mount by special order. The old unit leaves with me.
Repair the opener or replace it?
If the unit is roughly twelve years old or younger and the fault is a gear, sensor, trolley, remote or board, I repair it. Those parts are made to be swapped, and a repaired opener can run for years.
I recommend replacing when the motor is worn out, the board is discontinued, or the opener is so old it has no safety sensors. I'll tell you which side of the line yours is on before I quote, and if it's close, I'll price both.
When I replace, I install a LiftMaster with battery backup, which California has required on newly installed residential openers since 2019. If you want Wi-Fi so you can check the door from your phone, I'll set up the app before I leave.
There are four types, from least to most expensive. A chain drive is the basic one: tough, and fine for a detached garage. A belt drive costs a little more and is much quieter, which matters if there's a bedroom over the garage. A heavy-duty chain drive is built for big wood carriage-house doors that weigh 500 or 600 pounds; most steel doors, even insulated ones, don't need it. A side-mount (jackshaft) opener sits on the wall beside the door, so nothing runs down the middle of the ceiling. Chain and belt drives are on the truck. Heavy-duty and side-mount units are special order. If the garage is too tight for a standard rail, I install Marantec, which makes openers for tight spaces.
Spring snapped? I can usually come today or tomorrow.

A few things not to do
Don't turn up the force setting to get a stubborn door to close. That knob is part of the safety system. If the door needs more force, something is binding or a spring is weak, and the opener will crush whatever is under it before it reverses.
Don't run the opener with a broken spring, and don't tape or bypass the safety sensors to make a blinking light go away. If the door won't close and you need to leave, don't force it and don't pull the release cord. Lock the door between the garage and the house and call me. If the door is up, leave it up and call.

Why does my opener light keep blinking?
On most openers, a blinking light with a door that won't close means the safety sensors at the bottom of the tracks aren't lined up or can't see each other. Look at the little light on each sensor and check that nothing is blocking the beam. If one is off or flickering, call me and I'll sort it out.
Can you fix an opener you didn't install?
Yes. I repair Chamberlain, Genie, Craftsman, LiftMaster and most other residential brands. New installs are LiftMaster, or Marantec when the space is tight.
Do I really need battery backup?
In California, a newly installed residential opener has to have it. It's also practical: when the power goes out, you can still get the car out without pulling the release and lifting the door by hand.
How long does a new opener install take?
About two hours for a standard install, including programming your remotes and keypad and setting up the app. The old unit and the box leave with me.
My remote stopped but the wall button works. Is the opener dying?
Usually not. Try a fresh battery first. If that doesn't do it, the remote may have lost its code or the receiver may be failing. Reprogramming is quick and I can do it on the same visit.
Faster by phone. This works too.
