What's It Doing?
Opener Problems Come in a Lot of Forms.
Most Are Fixable.
Opener failure isn't always a dead motor. It could be a $15 capacitor, a misaligned sensor, a remote that needs reprogramming, or a logic board that's given up. The diagnosis matters as much as the repair - and that's where a lot of companies skip steps.
Here are the symptoms we hear most often and what they typically mean.
Nothing Happens at All
No sound, no light, no movement. Could be a power issue, a tripped breaker, a dead logic board, or a failed capacitor. We work through the sequence on-site before assuming the worst.
Starts Moving, Then Reverses
Usually a sensor issue or a travel limit setting that's off. The opener thinks something is in the door's path. Sensor alignment is a quick fix - we realign, test, and confirm before leaving.
Remote Doesn't Work, Wall Button Does
Remote or keypad issue - could be the batteries, a lost program, a frequency conflict, or a failed receiver in the opener itself. We diagnose which one and fix it on the spot.
Moves Slow or Sounds Strained
An opener laboring to move a door is usually fighting an unbalanced door - often a spring issue, not an opener issue. We check both and tell you exactly what's causing it.
Light Works, Motor Doesn't
Power is getting to the unit but the motor isn't engaging. Common causes: failed capacitor, stripped drive gear, or a motor winding that's burned out. Most are repairable without a full unit replacement.
Wi-Fi or App Connection Lost
Newer smart openers lose their network connection after firmware updates, router changes, or power outages. We reprogram and reconnect - and make sure everything is paired correctly before we leave.
Grinding or Loud Clicking
A grinding chain or belt drive usually means worn drive components or a gear that needs replacement. Loud clicking on engagement points to a stripped gear set in the opener head.
Sensor Light Blinking
Blinking safety sensor lights mean the photo-eye alignment is off or one sensor has failed. The door won't close fully until it's resolved. Usually a fast fix - we realign, clean, or replace as needed.
What We Work On
Every Brand. Every Component. Every Drive Type.
We service all major residential opener brands and every drive configuration - from basic chain drives to belt-drive smart systems with battery backup and myQ integration.
Brands We Service
LiftMaster & Chamberlain
The most common brands in the Denver metro - including myQ smart systems, 8500 series wall mounts, and older residential units. We carry common parts on the truck.
Genie
Chain glide, screw drive, and belt drive Genie units - including Aladdin Connect smart home integration. Logic boards, drive gear sets, and remote programming.
Craftsman
Including older Sears-era units that are no longer in production. We source compatible parts and program replacement remotes to match existing systems.
Linear, Overhead Door & Others
Less common residential brands - we assess on-site and source parts where repair is viable. If parts aren't available, we'll tell you straight and give you replacement options.
Components & Drive Types
Motor & Capacitor
Motor windings fail over time - capacitors often go first and are a common cause of "dead" openers that are actually still salvageable. We test before recommending replacement.
Logic Board
When the control board fails, the unit loses communication with everything - remotes, keypads, sensors. Logic board replacement is significantly less expensive than a full new opener.
Safety Sensors
Photo-eye sensors are required on every residential opener and they fail from physical impact, moisture, and sun exposure. We align, test, and replace as needed.
Remotes, Keypads & Smart Integration
Remote programming, external keypad replacement, HomeLink vehicle integration, and myQ or Aladdin Connect setup. We confirm everything works before we leave.
Drive Gear & Rail
Stripped plastic drive gears and worn trolley assemblies are a common failure point on chain and belt drive units. Gear kit replacement is usually a same-day repair. Considering an upgrade? →
Repair or Replace?
The Honest Answer Depends on the Opener.
The default approach here is repair. But there are situations where replacement is the smarter call - and you'll know which one applies before any work starts.
Repair Makes Sense When...
- ✅The unit is under 12-15 years old and otherwise functional
- ✅The failed component is a capacitor, sensor, logic board, or drive gear
- ✅The repair cost is significantly less than a new unit installed
- ✅You don't need smart home features and the current unit does the job
- ✅The motor is sound - just a peripheral failure
This covers the majority of service calls. Most openers that seem dead have a repairable component - not a failed motor.
Replacement Makes Sense When...
- →The unit is 15+ years old and experiencing multiple failures
- →The motor has failed and repair cost approaches replacement cost
- →Parts are discontinued or unavailable for the specific model
- →The opener lacks modern safety features (pre-1993 units have no photo-eye sensors)
- →You want quiet belt-drive, battery backup, or smart home integration
When replacement is the right call, we handle the full installation. Opener installation details →

Call or Submit the Form

On-Site Diagnosis
The full diagnostic sequence runs on-site: power, motor, logic board, sensors, drive components. You'll get a clear explanation of what's wrong and what caused it.
Price Before We Start
You get the repair cost before any work begins. If repair doesn't make financial sense versus replacement, you'll hear that too, with both numbers, so you can decide.

Diagnosis Before Recommendation
We run through the diagnostic sequence before recommending anything. A lot of opener "failures" are a failed capacitor or a misaligned sensor - not a dead unit. You deserve to know which one you have.

Franchise techs are often paid per sale. That shapes the conversation every single time. The incentive here is to fix your system correctly - repair is the answer when repair is the right answer.

Garage Door Opener Questions
What homeowners across the metro actually want to know before they call.
My opener is completely dead. Does that mean I need a new one?
Not necessarily. A dead opener is one of the most common calls we get, and a large percentage of them turn out to be a failed capacitor, a tripped internal breaker, or a logic board issue - none of which require replacing the whole unit. We diagnose on-site before making any recommendation.
How long do garage door openers last?
A well-maintained residential opener typically runs 10-15 years. Units that get heavy use without maintenance tend to fail sooner - usually the drive gear set or capacitor goes first. If yours is under 12 years old and experiencing a first failure, repair almost always makes more sense than replacement.
My remote stopped working but the wall button still works. What's wrong?
Fresh batteries are the first thing to rule out. If that's not it, the remote may have lost its programming, there may be a frequency conflict with a nearby device, or the antenna or receiver in the opener unit has failed. We work through the sequence on-site - most remote issues are resolved in a single visit.
The door reverses every time it tries to close. Why?
The two most common causes are misaligned safety sensors and an incorrect travel limit setting. The opener thinks something is blocking the door's path and reverses as designed. Sensor alignment is usually a fast fix. If the sensors are physically damaged, we replace them on the spot.
Can you work on my older opener? The brand might be discontinued.
Often yes. We work on Craftsman, Linear, old Sears units, and other discontinued brands. Compatible parts are available for many older models. We'll tell you on-site whether repair is viable - and if it's not, we'll give you a clear replacement option at the same visit.
Is it worth upgrading to a belt-drive or smart opener when I repair?
That's a real question worth asking when you're already paying for a service call. If your current unit is older and the repair cost is meaningful, we'll give you both numbers - repair vs. a new belt-drive or Wi-Fi unit fully installed - so you can make the call with actual numbers in front of you. No pressure either direction. Opener installation details →
