Garage Door Opener Repair in Lakewood and Denver
Garage door opener repair in Lakewood, Denver and the towns around them. When an opener hums, clicks, stops short or does nothing at all, the fault is usually one part: a gear, a board, a limit setting or a sensor. G Brothers diagnoses the fault before we quote and fixes many openers the same day. If the opener is past repairing, we say so.

Situations we fix every week
- Your opener clicks, but the door won’t budge?A click means the opener is getting power and trying. The door not moving usually points to a broken spring, a stripped drive gear, or the trolley disconnected. Here's how to tell which.How we fix it
- Not sure if your garage door opener is worth fixing?Most openers we're called about get repaired. We recommend a new one when the drive is worn out, it can't learn new remotes, or it won't hold its settings. Here's how we tell the difference.How we fix it
- Garage door remote or keypad stopped working?If the wall button still opens the door, the opener is fine and the problem is the remote, the keypad or the programming. On most of these calls we reprogram or replace the remote and you're done.How we fix it
- Does your garage door stop before it is fully open or fully closed?The opener has two settings that decide where the door stops: the travel limits and the force. When either drifts, or the door gets harder to move, it stops early or reverses. Here is how to tell which one it is.How we fix it
- Your garage door opener runs, but the door doesn’t move?When the garage door opener motor runs and the door stays put, the motor is turning but nothing is connecting it to the door. The usual causes are a disconnected trolley, a broken belt or chain, or a loose door arm.How we fix it
- Garage door opener humming or buzzing?A hum with no movement usually means the motor is trying and something is holding it back: a stuck door, a worn start part or a failing drive gear. A buzz while it runs is more often loose hardware. Stop pressing the button repeatedly and read the sound first.How we fix it
- Garage door opener completely dead?If the opener has no light, no click and no hum, it is not getting power or its board has failed. Check the plug, the GFCI and the wall console before you assume the opener is finished.How we fix it
- Garage door opens by itself?A door that opens with nobody pressing anything is a security problem and a fault. The usual causes are a stuck button, a remote being pressed in a bag, an old fixed code, or a failing board. Unplug the opener while you track it down.How we fix it
- Opener light stays on or blinks?A light that stays on is often a console setting, a stuck button or a bulb problem. Flashing lights can be the opener telling you it found a fault, often a safety sensor. Check which one you have before you change anything.How we fix it
- LiftMaster opener blinking or flashing?Blink patterns are the opener's way of reporting a fault. The exact meaning depends on your model, so find the label or your manual and match the count. Most patterns fall into a few categories: sensors, travel limits, the motor, the board, or a wall control.How we fix it
- Emergency release cord stuck?A release cord that will not move is usually binding because the opener is pressing on the trolley, or the cord has jammed. Do not yank it. If the door is also heavy, stop, because the real problem may be a spring.How we fix it
- Pulled the release and can't reconnect it?Reconnecting usually means getting the door and the carriage to the same spot so the trolley can latch. If it will not catch, the door may be out of balance, the lever bent, or the arm out of position.How we fix it

When to repair vs replace an opener
The opener hums or clicks but the door does not move, often a gear, a capacitor, or a broken spring
It runs then reverses, usually a sensor or a travel limit
The door stops short of open or closed, usually the limits or the force setting
It is older than about 15 years, loud, or has no photo-eyes: replace it instead
What our opener repair records show
Our shop is in Lakewood, so Lakewood, Wheat Ridge, Golden and west Denver are minutes away. These are the patterns from 186 opener repair visits in our job records.
Safety sensors come first. Sensors were the most common opener repair: 47 of 186 visits. A door that reverses or will not close is very often a sensor that is dirty, knocked out of line or failing.
Springs are often part of it. 48 of 186 opener visits also involved the springs. A broken spring makes the door too heavy, and the opener hums or clicks without lifting it, so we check the door before the opener.
Most visits are short. A typical opener repair takes about 39 minutes on site.
Many are fixed the same day. 88 of 186 opener repairs were finished the same day.
What sets the cost of an opener repair
The price depends on what failed, and we quote it after we find the fault, not before.
The part. Realigning a sensor or resetting the travel limits is quick. A logic board, a motor or a gear and sprocket kit is a bigger repair.
The opener. Brand, model and age decide which parts are still made and whether a repair is worth it.
The door. A broken spring or a door off balance has to be fixed first, or the new opener part wears out too.
The estimate is free, and you approve one flat price before any work starts.

Common questions
Quick answers about opener repair and related work from the G Brothers team.
Can my opener be repaired, or do I need a new one?
Many openers are worth repairing. If the unit is older, lacks safety sensors, or the board and motor are failing, a new opener is the better value. We give you the honest call.
What opener repairs do you do?
Stripped gears and sprockets, failed logic boards and capacitors, travel limits and force settings, trolleys, chains and belts, and safety sensors.
Should I check the springs before the opener?
Yes. A broken spring makes the door too heavy to lift, and the opener hums or clicks without moving it. We check the door first, so you do not pay to repair an opener that is fine.
Do you install new openers too?
Yes. When an opener is past repairing, see garage door opener installation. For new remotes and keypads, see remote and keypad programming.
Can a garage door opener be repaired, or does it need to be replaced?

Should you repair or replace your garage door opener? Repair a newer unit with one failed part. Replace one over 15 years old or missing safety sensors.
Read full answerDo the springs or the opener lift my garage door?
The springs lift your garage door, not the opener. They counterbalance the weight and the opener just guides it. Here is why that matters.
Read full answerHow do I troubleshoot a Chamberlain garage door opener?
Check the safety sensors first, then power, then the remote.
Read full answerWhat does it mean when my garage door opener is beeping?
A beeping garage door opener usually signals one of three things: a battery backup running low, an alert that the door has been open too long, or a warning that the opener needs service.
Read full answerWhy is my garage door opener grinding but the door still moves?
A grinding opener that still moves the door usually has a worn drive gear, a dry or gritty chain or belt, or debris in the rail.
Read full answerWhy is my garage door opener motor overheating and shutting off?
The motor has a thermal overload protector that cuts power when it gets too hot, usually after repeated cycles without a cool-down break, or because it is straining against a heavy or unbalanced door.
Read full answerWhy does my garage door opener only work sometimes?
Intermittent opener problems point to four main causes: a weak or dead remote battery, radio frequency interference near the opener, a dirty or misaligned safety sensor, or a loose wire on the wall button.
Read full answerWhat do the blinking lights on a Genie garage door opener mean?
Genie openers use blink codes from the motor unit LED to report faults.
Read full answerHow do I troubleshoot a Genie garage door opener?
Start with power, then the safety sensors.
Read full answerWhy is my garage door opener buzzing or humming?
A garage door opener starts humming or buzzing when the motor gets power but cannot turn the drive. The length of the sound tells you which fault it is. A one second hum points to a locked door, a broken spring, or a trolley jammed on the stop bolt. A constant buzz with the door idle is electrical.
Read full answerWhy does my garage door opener smell like it is burning?
A burning smell from a garage door opener comes from one of four places: a failing start capacitor, an overheating motor, a stripped plastic drive gear, or grease cooking off a hot housing. A sharp electrical or fishy smell means unplug the opener now. A faint grease smell that fades is usually harmless.
