Garage Door Opener Repair
Grinding but not moving, clicking but not lifting, reversing for no reason, working from the wall button but not the remote — opener trouble has a dozen faces and most have straightforward fixes. We repair every major brand (LiftMaster, Chamberlain, Genie, Craftsman and more) across San Antonio, and we'll tell you honestly when a repair beats a replacement — and when it doesn't.
Call now if…
- The opener hums or grinds but the door doesn't move
- The door reverses immediately after touching the floor
- Remotes or keypad stopped working (wall button still works)
- The trolley moves but the door stays put (stripped gear or disengaged carriage)
- The opener light blinks and the door refuses to close
The usual suspects
Nine times out of ten it's one of these: misaligned photo-eye safety sensors (the blinking-light, won't-close classic), a stripped drive gear, a worn trolley carriage, travel/force limits that have drifted, a failed logic board, or a chain/belt that's lost tension. Each has a distinct symptom — which is why a phone description to a tech who's heard them all often gets you a diagnosis before we arrive.
Is it really the opener?
Here's the honest part most companies skip: many 'opener' failures are actually spring or balance failures. The opener is designed to guide a balanced door, not lift dead weight — when a spring weakens, the opener strains, trips its force limits, and looks like the culprit. We test door balance first, because replacing a healthy opener to compensate for bad springs wastes your money.
Repair vs. replace, straight up
A stripped gear on a 5-year-old LiftMaster is worth repairing. A 20-year-old builder-grade unit with no safety sensors, no rolling-code security, and a fried board usually isn't — parts alone approach the cost of a new, quieter, safer unit. We'll price both paths and let you decide.
Common questions
Opener Repair FAQs
Why won't my garage door close, but it opens fine?
That's the photo-eye sensors, almost every time. The two little lenses near the floor must see each other; a bumped bracket, sunlight glare, or a cobweb breaks the beam and the opener refuses to close (or reverses and blinks its light). We realign and test them — and check wiring if realignment doesn't hold.
My remote works only from very close. What's wrong?
Usually a weak remote battery or radio interference (LED bulbs in the opener are a notorious culprit). If new batteries and swapping the bulb don't fix range, the receiver board may be failing — worth a service call before you're locked out in the rain.
Do you service my opener brand?
We work on all the major brands sold in Texas — LiftMaster, Chamberlain, Genie, Craftsman, Linear, Overhead Door and others — and carry common gears, sensors, and remotes on the truck.
