Fast, Expert Opener Repair You Can Trust
Most opener problems are fixable—and usually faster than you'd expect. Whether it's stripped gears, misaligned sensors, a dead circuit board, or just remote programming, we diagnose accurately and repair efficiently.
We service most major brands and all opener types. Every repair includes testing the entire system to make sure your door operates safely and reliably.
Signs Your Opener Needs Repair
- Motor runs but door doesn't move — you hear humming or grinding but the door stays put (stripped gears)
- Door reverses immediately when closing — opener light blinks, door won't close (sensor issue)
- Remote or wall button doesn't work — no response when you press the button (battery, wiring, or circuit board)
- Loud grinding, clicking, or popping sounds — motor is struggling or gears are worn (mechanical failure)
- Intermittent operation — works sometimes but not others (loose wiring, failing circuit board)
- Door only opens partway — starts moving then stops (limit switch or force setting issue)
- Opener runs continuously — motor doesn't stop running even when door is fully open/closed (limit switch problem)
- Slow or jerky movement — door moves sluggishly or in fits and starts (worn gears, capacitor failure)
Not sure what's wrong? Use our free DoorDiagnosis™ tool to walk through common symptoms. It helps identify whether the issue is your opener, springs, sensors, or something else—in under 60 seconds.
Common Opener Problems We Fix
Stripped Gears (Most Common Repair)
The motor runs but the door doesn't move. You hear humming or grinding, and sometimes see white plastic dust under the opener.
This happens when the main drive gear wears out—usually after 10-15 years of use. We replace the gear assembly, lubricate the system,
and test everything to make sure it operates smoothly.
Sensor Alignment Issues
The door won't close and the opener light blinks. Your photo eye sensors (the small units near the floor on each side of the door)
need to "see" each other for the door to close. If they're misaligned, dirty, or have a loose wire, the door won't close for safety reasons.
We realign, clean, or replace sensors as needed.
Remote & Keypad Programming
Lost your remote, bought a new one, or need to program a keypad or car's HomeLink system? We program all types of remotes and access devices.
Can also erase old remotes if you're concerned about security (previous owners, lost remotes, etc.).
Circuit Board Failure
The opener works intermittently, doesn't respond to remotes, or has erratic behavior (opens on its own, stops randomly).
The circuit board (logic board) controls all opener functions. When it fails, behavior becomes unpredictable. We replace the board
and reprogram all remotes and settings.
Broken Trolley or Carriage
The trolley is the piece that connects the opener arm to the door. If it's broken or disconnected, the motor runs but nothing moves.
Common on older units or after someone pulled the emergency release and forced the door. We replace the trolley assembly and reconnect everything properly.
Capacitor Failure
The motor hums but won't start, or starts very slowly and lacks power. The capacitor gives the motor the electrical "kick" it needs to start.
When it fails, the motor struggles. We replace the capacitor and test motor performance.
Limit Switch Problems
The door only opens partway and stops, or it runs past the fully open/closed position. Limit switches tell the opener when to stop.
If they're out of adjustment or faulty, the door won't open/close completely. We adjust or replace limit switches to restore proper travel.
Wiring & Connection Issues
Intermittent operation, remote works sometimes but not always, or wall button doesn't respond. Loose or damaged wires cause unpredictable behavior.
We trace wiring, fix connections, and replace damaged wire runs as needed.
When to Repair vs. Replace Your Opener
Not every opener problem is worth repairing. Here's our honest assessment:
Repair makes sense when:
- Opener is less than 10 years old
- Problem is a single component (gear, sensor, circuit board)
- Repair cost is under $300
Replacement makes more sense when:
- Opener is 10+ years old
- Motor itself is failing or dead
- You've had multiple repairs already
- Opener lacks modern safety features (no photo eyes, no auto-reverse)
- You want smart features (app control, notifications)
- Opener is extremely loud and you want quiet operation
- Repair cost approaches 50%+ of a new opener
We'll give you the honest recommendation. If your opener is on its last legs, we'll tell you. If a simple repair will give you another 5-10 years, we'll tell you that too. No upselling, no pressure—just the facts.

Honest Repair vs. Replace Advice

Not Sure If It's Your Opener or Something Else?
Our free DoorDiagnosis™ tool helps you identify whether the problem is your opener, springs, sensors, or another component. Answer a few quick questions and get a diagnosis in under 60 seconds.
Diagnose The Problem Now How do I know if my garage door opener needs repair? ▶
Common signs include the opener motor running but the door not moving, grinding or clicking noises from the motor, door reversing immediately after trying to close, remote or wall button not responding, or the opener working intermittently. If your opener is making unusual sounds or behaving unpredictably, it likely needs professional diagnosis and repair. Our free DoorDiagnosis™ tool can help you identify the issue in under 60 seconds.
Why does my opener run but the door doesn't move? ▶
This is usually caused by stripped gears inside the opener. The motor runs and you hear it humming or grinding (sometimes with a white plastic dust appearing under the unit), but the gear that connects the motor to the drive mechanism is broken or worn out. This is one of the most common opener repairs and is typically fixed by replacing the gear assembly.
Why won't my garage door close all the way? ▶
If the opener light blinks and the door reverses when you try to close it, the photo eye sensors are likely misaligned or blocked. These sensors are mounted on either side of the door near the floor and must "see" each other for the door to close. Check for obstructions, dirt on the sensor lens, or sensors that have been bumped out of alignment. If the sensors look clear and aligned, the issue might be a faulty sensor, loose wiring, or a circuit board problem requiring professional repair.
Should I repair or replace my garage door opener? ▶
If your opener is less than 10 years old and the repair is relatively minor, repair makes sense. If your opener is 10+ years old, has had multiple failures, or the motor itself is dead, replacement is usually the smarter choice. Older openers lack modern safety features like automatic reversal and photo eye sensors, and they don't have smart capabilities like smartphone control. We'll give you an honest assessment and let you make the decision.
Do you repair all brands of garage door openers? ▶
Yes, we service all major garage door opener brands including LiftMaster, Chamberlain, Genie, Craftsman, Sears, Linear, and Guardian. We work on chain-drive, belt-drive, screw-drive, and wall-mount (jackshaft) openers. We keep common repair parts in stock and can source specialty components for older or uncommon models.
