Garage door opener repair: what to know

What the job involves, what changes the price, and what to ask a pro.

What garage door opener repair is

Garage door opener repair troubleshoots an opener that will not open, will not close, reverses for no clear reason, or has lost its remotes. The work checks the sensors, the logic board, the gears, the limit settings and the remotes, then replaces the parts that have failed. People call when the opener has stopped working, behaves oddly, or when a remote or keypad needs to be reset.

Signs you need it

  • An opener that hums but does not move the door, or that stops partway through its travel
  • A door that closes and then reverses back up for no clear reason
  • Remotes or the wall control that no longer respond, even with new batteries
  • Sensor lights that are off or blinking, or sensors that no longer stop the door
  • Grinding, clicking, or a burning smell from the motor or the gear, which means stop using the opener and call a pro

What the pro does

  • Check the power to the opener, the wall control and the remotes, and test the door's manual release from inside the garage
  • Inspect the safety sensors for alignment, clean the lenses, and check the wiring for damage or loose connections
  • Check the logic board, the limit settings and the force settings, and look for signs of a failed board or motor
  • Inspect the gear, the drive chain or belt, and the trolley for wear, and replace any part that has failed
  • Reprogram the remotes and keypad, reset the limits, and test the reverse and the sensors before you leave

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • Part that has failed, such as a logic board, a sensor, a gear, a motor or a belt
  • Opener age and model, and whether its parts are still available
  • Sensor or wiring repair, including damaged cable runs
  • Remote and keypad programming, and the number of devices
  • Access to the opener, such as a high ceiling or a tight ceiling space
  • Whether the opener should be replaced rather than repaired
  • Emergency timing when the car is locked in the garage

What a written quote should spell out

  • Each part to be replaced listed by name, with the model or rating
  • Sensor and wiring repairs listed as separate lines, with the cable runs noted
  • Remote and keypad programming, with the number of devices reset
  • Limit and force settings adjusted, and the reverse test result
  • Diagnosis and labor, with the test steps shown
  • Warranty on the replaced parts and the labor

Questions to ask before you hire

  • Which part has failed, and can you show me the failed part or the test result?
  • Will the remotes be reprogrammed, and how many devices are included?
  • If the opener is old, is it worth repairing, or should we talk about replacing it?
  • How do you test the safety reverse after the repair?
  • Are the parts still made for my opener model?
  • What warranty covers the parts and the labor?
  • Who does any wiring repair, and is that person a licensed electrician if the power is involved?

Red flags

  • A repair that bypasses the safety reverse or the sensors to make the door close
  • A tech who cannot show the failed part or the test results
  • A repair that leaves the force set too high for the door to reverse safely
  • Opener parts replaced with generic parts that do not match the model
  • Pressure to replace the whole opener when a sensor or a remote is the actual fault

What you can do yourself

You can safely replace the remote and keypad batteries, clean the sensor lenses, and check that the sensors line up and nothing blocks the door's path. Do not open the opener's housing or touch its wiring, and never bypass the safety reverse. Call a pro for a sensor that will not align, a motor that hums without moving, or any opener that reverses without a clear cause.

Licenses and permits

Garage door opener repair is commonly done by licensed garage door or general contractors, and rules vary by place. Check with your state and local licensing agency, and make sure any wiring or power repair goes to a licensed electrician.

Garage door opener repair questions

Why does my remote stop working?

The battery, the antenna, or the remote's sync with the opener is usually the cause. Replace the batteries first. If the remote still fails, the opener's receiver may need to be reset or reprogrammed.

Why does my door close and then reverse?

The safety reverse may be triggered by a sensor that is out of line, a blocked sensor, or a closing force set too sensitive. A pro should check the sensors and the force before adjusting anything.

Can a logic board be replaced?

Yes, on many openers. Some boards are part of a larger assembly. A pro should check the board, the model and the warranty before recommending a replacement, and explain the choice.

How often should I check the safety reverse?

Test it at least once a month. Place a flat object on the floor under the door and close it. The door should reverse when it touches the object. Call a pro if it does not.
