Garage door opener repair in Corpus Christi usually comes down to the safety sensors, the remote or keypad, a worn drive gear, or a door the opener can't lift.

First, rule out the door itself

An opener is the motor, not the muscle. The springs hold the door's weight, and the opener moves a door that's already balanced. DASMA says it plainly: if a door feels heavy, it is probably out of balance, and "the answer is not a more powerful garage door opener."

So before blaming the opener, pull the emergency release with the door closed and lift it a few feet by hand. If it's heavy, slams, or won't stay put halfway, the problem is the springs, not the opener. Stop there and read about spring repair. If it lifts smoothly, the opener is the likely culprit.

Common opener problems and what they mean

Door starts down, then reverses. The safety sensors are the usual suspect. Since 1993, DASMA notes, every opener made for the U.S. must have a second safety-reversing feature, usually photo eyes near the floor. If the beam is blocked or the eyes are out of line, the door goes back up. DASMA also says the eyes should be mounted no higher than six inches above the floor so a child or pet can't slip under the beam.

Opener hums or clicks, door doesn't move. Check that the door's manual lock isn't engaged. If it isn't, the cause is often a broken spring (the opener senses the weight and quits) or a stripped drive gear inside the unit.

Remote works up close only, or not at all. Start with the battery. If a new battery doesn't help, the remote may need reprogramming or the opener's antenna may be damaged.

Door stops partway or closes too hard. The travel limits or force setting may be off. DASMA says that if a door doesn't reverse readily after contacting an obstruction, the sensitivity setting may be wrong, which "can create a dangerous situation," and it recommends a trained technician make the adjustment.

Opener runs, door doesn't move. The trolley may be disconnected (someone pulled the release), or the chain, belt or gear has failed.

Openers on the coast

Sensors and dust. Photo-eye lenses collect grime and salt film like any glass near the bay. Wipe both lenses with a soft cloth before you call anyone. It costs nothing, and it's the first thing a technician would check.

Power outages. Storms here take power out for long stretches. During Harvey, NOAA's storm records note numerous power poles blown down or snapped in Nueces County, and the Weather Service says the hardest-hit areas likely lost power for several weeks. Know where your emergency release cord is, and practice using it with the door closed and the springs working. If you want the door to work during outages, ask the company about openers with battery backup.

Rust at the rail and bracket. The opener's metal rail, header bracket and door bracket corrode like the rest of the hardware. A loose or rusted bracket at the top section of the door is worth fixing before it pulls out. DASMA warns that skipping the opener reinforcement bracket on the door's top section can damage the door.

What opener work costs

Thumbtack puts a new opener with installation at about $390 to $650, and the opener alone at about $150 to $300. HomeAdvisor's figure for installing an opener is about $220 to $520 on average, with the price moving on the opener type, horsepower, remotes, lighting and parts availability. The two guides use different data, so treat them as a range to check a quote against, not a price list. Repairs to sensors, remotes and gears depend on the part; ask for the price in writing before work starts. More figures are in the garage door repair cost guide.

Things you can safely check yourself

Wipe both sensor lenses and make sure nothing sits in the beam.
Look for a steady light on each sensor. A blinking or off light usually means they're out of line.
Replace the remote battery.
Check that the manual lock on the door is open.
Make sure the wall button is at least five feet off the floor, where DASMA says it belongs, out of children's reach.
Watch the door until it's fully closed every time, as DASMA advises.

Don't adjust springs, cables or bottom brackets to "help" the opener. DASMA's checklist says those adjustments belong to a trained door systems technician.

Questions to ask the company

Is the problem in the opener or in the door's balance?
If you recommend a new opener, what drive type (chain, belt or other) and why?
Does it include battery backup and rolling-code remotes?
Is the price all-in, including removal of the old unit?
What written terms come with the opener and the labor?

If the door is heavy by hand, start with garage door spring repair. If it's crooked or a roller has jumped the track, see cable, roller and track repair. Getting a new door? The opener is often swapped at the same time; see new garage door installation. More answers are on the questions page.

Common questions

Is it worth repairing a garage door opener?

Often, for a newer opener with a sensor, remote or gear problem. If the opener has no safety sensors near the floor, DASMA says it's time for a new one: since 1993, openers made for the U.S. must have a second safety-reversing feature such as photo eyes. Thumbtack puts a new opener with installation at about $390 to $650.

Why does my door go down and come right back up?

Most often the safety sensors near the floor can't see each other: a dirty lens, a bumped bracket, or something in the beam. Wipe both lenses and check that their indicator lights are steady. If it still reverses, the force or travel settings may need adjusting, which DASMA recommends leaving to a trained technician.

How do I open the garage when the power is out?

Close the door first if you can, then pull the emergency release cord (usually red) and raise the door by hand. Skip this if a spring is broken: the door will be dangerously heavy. Once the power is back, re-engage the trolley following your opener's manual.

Will a stronger opener fix a door that's hard to lift?

No. DASMA says a door that feels heavy is probably out of balance, and 'the answer is not a more powerful garage door opener.' Openers are designed to move doors that are properly balanced. Have the springs checked first.
