Short answer
Most Houston garage door openers that hum but will not lift have either a stripped drive gear or a broken spring behind them, and opener repairs typically run $180 to $360 according to Inch Calculator's 2026 figures. We test the door's balance first, because an opener fixed on a door with a dead spring just fails again.
Signs the opener needs attention
Humming with no movement
Stripped gear, or a broken spring the motor cannot lift.
Clicking, then nothing
Often a capacitor, a relay or the logic board.
Lights blinking in a pattern
A diagnostic code worth reading before replacing parts.
The door stops short
Travel limits or force settings have drifted.
Remotes work only up close
Antenna, remote battery or board faults.
How an opener repair runs
Balance test
Release pulled, door lifted by hand to rule out the springs.
Read the codes
Diagnostic lights and a look at the gear, board and wiring.
Price before work
Repair or replace, with the reasons for each.
Repair and adjust
Parts replaced, limits and force reset, rail and chain tensioned.
Safety test
Auto-reverse with an object under the door, then full cycles.
Repair the opener, or replace it
An opener only guides the door; the springs do the lifting. When a spring weakens, the motor and its plastic drive gear take the load, and the gear is usually what gives out. So our first step on any opener call is to pull the release and lift the door by hand.
If the door is balanced, the fault is in the opener: a worn gear, a failed logic board, travel limits that drifted, or a sensor circuit. On LiftMaster, Chamberlain and Genie units most of those parts are still made, and a repair makes sense on an opener with years left in it.
Opener hums but the door stays put
A hum with no movement means the motor is running but nothing is turning the chain or belt, or the door is too heavy to move. If the door lifts easily by hand, the drive gear has stripped. If it does not, the spring is the real problem and the opener was only the first thing to complain. Running the opener against a dead spring for long can also overheat the motor, which is why we ask you to stop pressing the button once the hum starts and call instead.
Stripped drive gear
Most chain and belt openers turn the drive sprocket through a plastic gear that is designed to strip before the motor burns out. Replacing the gear and sprocket assembly is a common, reasonably priced repair on an opener that is otherwise sound, and we grease it and re-set the limits afterward. On belt-drive models the matching part is a pulley and gear set instead, and we check the belt for stretch while the cover is off, because a slipping belt can mimic a stripped gear. Most gear jobs finish within a single visit.
Logic board and travel limits
Lights that blink in a pattern, a door that stops short or runs too far, or a remote that works only sometimes usually point to the logic board or the limit settings. Power surges during storms are hard on boards. We read the diagnostic code, reset the limits and force, and replace the board when it has failed. If the board has failed on an opener old enough that the board is discontinued, we tell you before ordering parts, since a new opener may cost little more.
Why outages hit Houston openers hard
Houston openers spend part of every summer at the mercy of the grid. When Hurricane Beryl came through in July 2024, CenterPoint called its outage of 2.26 million customers the largest in its history, and openers without battery backup simply stopped. When power comes back after storms like that, boards that took a surge and doors that were forced by hand are both on our list of things to check before we touch the opener.
Brands we service and install
We repair LiftMaster, Chamberlain, Genie and Craftsman openers most often, along with the commercial operators used on shop and warehouse doors.
What opener repair costs
Inch Calculator's 2026 guide puts opener repairs at $180 to $360 and opener replacement at $300 to $500. This Old House lists chain-drive units such as Chamberlain models at $200 to $300 for the unit itself. These are national ranges; we price your opener on site.
- 1
The failed part. A gear kit costs less than a logic board or a motor.
- 2
Opener age and brand. Parts for current models are easier and cheaper to get.
- 3
Door balance. A bad spring has to be fixed too, or the opener fails again.
- 4
Sensors and wiring. Damaged wire runs add time.
- 5
Remotes and keypads. Reprogramming is quick; new remotes add parts cost.
Questions about this job
Garage door opener questions
Either the drive gear has stripped or the door is too heavy because a spring broke. Lift the door by hand with the release pulled to tell which.
If parts are still made and the unit runs well apart from one fault, usually yes. Without a battery backup or with discontinued parts, replacing it is often the better choice.
Yes, along with Genie and Craftsman, which together cover most openers in Houston garages.
Many openers blink a diagnostic code, often for sensors. The number of flashes tells us where to look.
Yes. Surges can damage the logic board, which is a common repair after storms.
Yes. Many current openers take a battery backup that runs the door for a while during an outage.
