When your garage door opener stops responding in Sunnyvale, you’re usually dealing with one of three things: a failed logic board, stripped drive gears, or misaligned safety sensors. That’s where our Garage Door Opener Repair in Sunnyvale comes in. Commodore Garage Door Repair fixes all three, plus the less common failures like capacitor burnout and limit switch drift, usually in a single visit. Our techs arrive with brand-specific diagnostic gear for LiftMaster, Chamberlain, Genie, and Craftsman systems, so we’re not guessing at the problem. Call (877) 358-3130 and Nate Holloway or one of our senior techs will give you a straight diagnosis over the phone before we even dispatch. In most Sunnyvale neighborhoods, we can have a truck at your door the same day.
What sets us apart is simple: we repair what you already own. We’re not a replacement shop that defaults to selling you a new unit when a $40 gear kit would do. Commodore Garage Door Repair works fluently across the brands already installed in Sunnyvale garages, and we carry the parts that commonly fail on them. That’s Commodore-level reliability: show up knowing the equipment, fix the actual problem, and quote the price before any work begins.
Key Takeaways:
- Opener repair in Sunnyvale runs $120 – $320 for most jobs.
- We service LiftMaster, Chamberlain, Genie, Craftsman, and Raynor openers.
- Same-day dispatch is standard for Sunnyvale residents.
- Repair-first philosophy: we fix the unit you have, not push a replacement.
- Full-system coverage: door, springs, cables, tracks, and the motorized opener.
Garage Door Opener Installation
Garage Door Opener Installation is the service you need when you’re adding an opener to a new door, converting a manual door to motorized operation, or upgrading to a smart system with battery backup and Wi-Fi control. Commodore Garage Door Repair installs openers from LiftMaster, Chamberlain, Genie, and Craftsman, with installation pricing for Sunnyvale homes typically running $250 – $550 depending on the drive type and whether new wiring or bracing is required. Every install includes safety sensor alignment, force and travel limit calibration, and a full demonstration of remote and keypad functions before we leave.
Smart Opener Upgrades
Many Sunnyvale homeowners are replacing older chain-drive units with belt-drive or wall-mount openers that run quieter and include smartphone control. We’ll explain the real differences between drive types and help you pick the system that matches how you actually use your garage, not the one with the most features you’ll never touch.
New Construction and Additions
If you’re finishing a garage or building an ADU, we coordinate opener installation with the door install so the whole system goes in as one integrated unit. This avoids the mismatch problems we see when a door contractor and an electrician both work on the same opening without talking to each other.

Garage Door Opener Replacement
Garage Door Opener Replacement is the right call when your current unit has a failed motor, a cracked logic board, or repeated gear failures that make repair uneconomical. Commodore Garage Door Repair takes a straight-line approach: we diagnose first, quote the repair cost, and only recommend replacement when the math clearly favors it. For Sunnyvale homes, replacement typically runs $250 – $550 including the new unit and installation labor, and we haul away the old opener at no extra charge.
When Replacement Beats Repair
If your opener is 12 to 15 years old and the motor is drawing high amperage while the door struggles to lift, you’re near the end of the unit’s service life. Spending $280 on a repair for a unit that will fail again in six months is a poor use of your money, and we’ll tell you that directly.
Direct Brand Swaps
Your LiftMaster system is one we know well. We’ll replace it with the current equivalent model so your existing wall console, remote, and wiring harness usually carry over without modification. That keeps the swap simple and the price down.
Garage Door Remote Programming
Garage Door Remote Programming covers syncing new or existing remotes, keypads, and vehicle-integrated buttons to your opener, and it’s a service we handle daily in Sunnyvale for $120 – $320 depending on how many devices need programming and whether the opener’s receiver needs attention. The most common issues we see are remotes that worked for years suddenly losing sync, new remotes that won’t pair, and keypads that accept the code but won’t trigger the door. We fix all of them without replacing the opener.
Multi-Vehicle and Multi-Remote Setup
Families with three or four drivers often end up with a mix of working and dead remotes. We’ll program every remote, keypad, and vehicle button in one visit, and test each one at the curb line so you’re not discovering dead buttons the next morning.
After a Power Outage or Surge
Power fluctuations in Santa Clara, Cupertino Garage Door Opener Repair, and Fremont knock openers out of sync more often than mechanical failure does. If a brownout wiped your remote memory, we’ll reprogram your devices and check the opener’s capacitor and control board for latent damage before it becomes a bigger repair.
Garage Door Opener Battery Replacement
Garage Door Opener Battery Replacement solves the problem of an opener that runs fine on wall power but won’t lift the door when the power goes out, plus failing remote and keypad batteries that leave you clicking a dead button. For Sunnyvale homeowners, battery replacement typically runs $120 – $320 when bundled with a full opener inspection, and we carry fresh batteries for LiftMaster, Chamberlain, Genie, and Craftsman units on every truck. The battery inside your opener’s backup unit degrades over 2 to 3 years, and we test it under load, not just with a voltmeter.
Backup Battery Testing and Replacement
Most smart openers sold in the last five years include a battery backup that loses capacity in the heat of a Mountain View Garage Door Opener Repair summer. We test those batteries under actual motor load, and if they’re weak, we replace them on the spot so the backup actually works when PG&E has an outage.
Remote and Keypad Batteries
Before we touch the opener itself, we’ll check the remote batteries and the keypad. Half the “opener failure” calls we get in Sunnyvale are actually dead 9-volt and coin-cell batteries, and that’s a two-minute fix we’ll handle as part of any service call.
Garage Opener Maintenance
Garage Opener Maintenance is the scheduled service that catches drive gear wear, sensor drift, and force setting creep before they shut your garage door down, and it’s priced at $120 – $320 for a full opener tune-up in Sunnyvale. Commodore Garage Door Repair recommends a maintenance visit once a year for openers over five years old, and more often if your door faces afternoon sun or your garage gets heavy daily use. We treat the opener and the door as one system, because a sticky roller or a sagging spring makes the motor work harder and shortens its life.
Annual Opener Tune-Up
We check the drive, the motor’s electrical draw, the force settings, the travel limits, and the safety sensors, then lubricate the rail, the chain or belt tension, and the door’s moving hardware. Most Sunnyvale homeowners notice immediately how much quieter the system runs afterward.
Preventative Diagnostics
We listen for the motor’s pitch under load and measure its amp draw while the door cycles. A motor pulling more amps than spec is working too hard, and in most cases the cause is a door balance issue we can fix before the motor burns out entirely.
Garage Door Opener Not Working
Garage Door Opener Not Working is the call we get most in Sunnyvale, and the cause usually falls into one of four buckets: no power to the unit, a sensor alignment fault, a stripped drive gear, or a dead logic board. Commodore Garage Door Repair diagnoses the problem over the phone in about five minutes, then sends a truck with the parts that match your symptom, so most opener failures are fixed the same day for $120 – $320. If your opener is dead but the door is closed and your car is inside, that’s an emergency for same-day service and we’ll prioritize the dispatch.
Electrical and Power Issues
We check the outlet, the breaker, the opener’s internal fuse, and the capacitor before we touch any mechanical component. The majority of “dead opener” calls in Sunnyvale trace back to a tripped GFCI on the garage circuit or a failed capacitor, not a destroyed motor, and those are inexpensive fixes.
Sensor and Alignment Failures
If your opener runs for a second then reverses, or the door won’t move at all, the safety sensors are the usual suspects. We’ll clean the lenses, realign the beams, and check the wiring at the sensor heads, then test the door with the obstacle-detection feature working correctly, which is a safety requirement for any motorized door.
Garage Door Motor Replacement
Garage Door Motor Replacement becomes necessary when the motor itself has burned out or seized, and the rest of the opener assembly is still in good condition. Commodore Garage Door Repair handles motor replacement for LiftMaster, Chamberlain, Genie, and Craftsman openers, with Sunnyvale pricing typically falling in the $250 – $550 range when we’re replacing the motor and drive components together. In some cases we can replace just the motor, and in others the gears and sprockets have been damaged by the failure and need to go with it.
Motor Failure Diagnosis
A motor that hums but doesn’t turn is telling you the capacitor or the windings have failed. A motor that runs hot and trips its thermal overload after one cycle is telling you the door is out of balance and the motor has been overworked. We diagnose both accurately because we test the motor’s draw under load, not just listen to it.
Replacing the Motor vs. the Whole Opener
If the rail, belt or chain, and logic board are in good shape, a motor replacement makes financial sense. If two or more major components are failing, we’ll show you the numbers for a full opener replacement and let you decide, because the repair-first approach means we present the repair cost honestly even when replacement is the smarter long-term move.
Brands We Service
Commodore Garage Door Repair works on LiftMaster and Chamberlain openers daily, and we stock the OEM drive gears, logic boards, and capacitors that keep these units running for another five to ten years. Your LiftMaster system is one we know well, from the early chain-drive units with mechanical limit switches to the current models with MyQ and battery backup. We maintain the programming equipment to sync remotes and vehicle buttons without calling tech support or waiting on hold.
We also service Genie, Craftsman, and Raynor openers, and we’re just as comfortable with a 30-year-old Craftsman chain-drive as we are with a wall-mount Genie. If you’re not sure what brand is hanging in your garage, tell us what the motor housing looks like and we’ll identify it over the phone. One call covers the door and the opener, whether you have a Raynor or any other make.

AfterSigns You Need a Pro Right Now
- The opener runs but the door doesn’t move. This is the classic stripped-gear or broken-drive symptom on LiftMaster and Chamberlain units. The motor spins, but the door isn’t connected to it anymore, and continued cycling can damage the motor shaft and turn a $120 gear repair into a $400 motor replacement.
- The door reverses immediately after touching the floor. Your travel limit or force setting has drifted, or the safety sensors are seeing something that isn’t there. Left unfixed, the door won’t close fully, leaving your garage unsecured and your house exposed.
- The opener makes a grinding or rattling noise. That’s metal on metal, usually a failing sprocket or chain tensioner. Driving it daily while it grinds wears the rail and the motor bearings, and the repair bill grows every time you push the button.
- The opener works sometimes and not others. Intermittent operation often points to a failing capacitor, a loose wire, or a logic board with a cracked solder joint. These failures become permanent, and they usually do it on the morning you’re already late.
- The opener smells hot or trips the breaker. A motor pulling excessive amperage is a fire risk and a sign the door’s balance is off or the motor’s windings are shorting. We treat this as an urgent call in Sunnyvale and dispatch a tech immediately.
Our Process, Step by Step
- 1
Phone diagnosis. When you call (877) 358-3130, we’ll ask specific questions about the brand, the symptoms, and what you’ve already tried. Nate Holloway or a senior tech handles this call, and in most cases we’ll have a working theory before we hang up, so the truck carries the right parts.
- 2
On-site inspection and load testing. We test the motor’s amp draw while the door cycles, check the force and limit settings, inspect the sensors, and run the door manually to check balance. We don’t guess at the problem, we measure it.
- 3
Straight diagnosis, clear options. We’ll tell you exactly what failed, what it costs to fix, and how long it’ll last. If replacement is the smarter call, we’ll show you the numbers and let you decide. No upsell pressure, no scare tactics, no “while we’re here” games.
- 4
Repair and recalibration. We replace the failed component, then recalibrate the travel limits, force settings, and sensor alignment. We cycle the door 20 to 30 times and recheck everything, because a repair that works on the test bench but fails on the third cycle isn’t a repair.
- 5
Final walkthrough and quote. You get a written invoice with the work performed and the warranty on the parts, and we’ll show you how to maintain the system so you don’t call us back for the same problem. The price is quoted and agreed before any work starts, and it doesn’t change unless you approve additional work in writing.
How Much Does Garage Door Opener Repair Cost in Sunnyvale?
A typical garage door opener repair in Sunnyvale runs $120 – $320, with the most common jobs falling in the middle of that range. A stripped drive gear on a Chamberlain or LiftMaster chain-drive usually lands around $180 – $240. A failed capacitor or travel limit switch tends to run $120 – $180. A logic board replacement on a smart opener typically costs $250 – $320 for parts and labor. If you’re looking at a full opener installation or replacement, that’s a separate job, priced at $250 – $550.
What affects the price is mostly the part and the access. If your opener is a wall-mount unit installed in a tight space, labor takes longer than a standard overhead chain-drive. If the opener is old enough that parts are discontinued, we’ll source a compatible replacement and tell you before ordering. The best way to avoid overpaying is to work with a company that diagnoses before it quotes, and that’s how we operate. Every estimate is free, it’s itemized, and the price we quote is the price you pay, because we agree on it before the work starts. If the repair doesn’t make economic sense, we’ll tell you that too, and we’ll show you the replacement numbers side by side. Call (877) 358-3130 for an exact quote on your opener.
