Garage Door Opener Repair

This is the most common sign of stripped internal gears. The motor is running, but the damaged gears can't transfer power to the drive mechanism. Gear replacement is a straightforward repair that usually takes about an hour.

The most likely cause is misaligned safety sensors. If the infrared beam between the two sensors is broken or blocked, the opener thinks there's an obstruction and reverses. Other causes include incorrect force settings or a failing logic board.

If the wall button operates the door normally but the remote does nothing, the issue is either a dead remote battery, a failed remote, or a bad receiver board in the opener. If multiple remotes all fail at the same time, the receiver board is the likely culprit.

Same-day service is available throughout the St. Louis metro area. We carry common replacement parts on our trucks, so many repairs are completed in a single visit.

It depends on the problem. A sensor adjustment is very different from a gear replacement or a circuit board swap. We provide a clear quote after our inspection, before any work begins. You'll know exactly what it costs before you decide to proceed. Our diagnosis is free in qualifying ZIP codes near Chesterfield (63005, 63017, 63011, 63021, 63038, 63040, 63088, 63131, 63141, 63122, 63124). Outside these areas, the diagnostic fee is $89 within 15 miles or $129 within 30 miles — both credited 100% toward any repair completed the same day.

It depends on the unit's age and condition. If a single component failed on an opener that's less than 10 to 12 years old, repair is usually worthwhile. If the motor is failing, the unit is 15+ years old, or you're stacking multiple repairs, a new LiftMaster opener with a full warranty is often the smarter investment.

Yes. An opener that activates without input can indicate a wiring short, a failing circuit board, or radio interference. This is both a security risk and a safety hazard. Stop using the opener and call us right away.

No. We diagnose and repair openers from all major manufacturers. However, as a Certified LiftMaster Dealer, our primary focus is LiftMaster. When a circuit board or gear assembly fails on other brands, a full replacement with a new LiftMaster is often more cost-effective than sourcing discontinued parts. We'll always give you an honest comparison.

Absolutely. St. Louis thunderstorms deliver frequent power surges that can fry opener circuit boards and logic chips. A surge protector on the outlet powering your opener is a simple and inexpensive safeguard. If your board is already damaged, we can often replace it without replacing the entire unit.

Our 26-point inspection covers the opener motor, drive mechanism, safety sensors, remotes, wall controls, travel limits, force settings, and all related door components including springs, cables, rollers, tracks, panels, and hardware. We find the root cause, not just the symptom. The inspection is free for qualifying ZIP codes near Chesterfield. Outside those areas, a diagnostic fee applies but is credited 100% toward any repair completed the same day.
