Two shops turned us down flat once they heard how old the 648PRO is — one of them would not even send a technician to look at it. This company came out, put a meter on it, and had the answer within the hour: the defrost termination thermostat had quit, so the coil never cleared and the freezer side kept climbing. It has sat rock steady since.

A Thermador Isn't a Generic Appliance — and Shouldn't Get Generic Service
Thermador engineers around ideas no mainstream brand bothers with: the star-shaped burner port that spreads flame evenly to the edge of the pan, the ExtraLow setting that cycles a burner down to a true melt-and-warm heat, and the Freedom Induction surface that lets you set a pan anywhere and have the coils find it. That cleverness is exactly why a parts-cannon repair goes wrong — the component that failed is rarely the obvious one.
Castle Rock Appliance Service has focused on premium and built-in appliances since 2014, and Thermador is a brand we work on constantly across Douglas County. We are an independent company, not affiliated with or authorized by Thermador, Sub-Zero, Wolf, Viking or any manufacturer. What that buys you is unhurried, component-level diagnostics and OEM-quality, factory-specified parts — without dealership markup or a multi-week wait on a repair ticket.
The Thermador Products We Service
From the cooking suite to cold storage to the dishwasher and the hood, we cover the full Thermador lineup found in Front Range homes.
Ranges & Cooktops
Pro Grand and Pro Harmony ranges with sealed Star Burners, plus Masterpiece gas, electric and Freedom Induction cooktops. We handle ignition faults, weak ExtraLow simmer, and the altitude calibration these gas burners need at 6,200 feet.
Refrigeration & Freezers
Freedom Collection built-in columns, French-door bottom-freezers and Professional refrigerators. Sealed-system diagnosis, dual-evaporator faults, Diamond ice makers, and gaskets dried out by Colorado air are the calls we see most.
Ovens & Steam Ovens
Masterpiece and Professional wall ovens, including convection, steam-and-convection, and combination units. Bake and broil elements, convection motors, door-hinge SoftClose mechanisms and temperature sensors are all in scope.
Dishwashers & Ventilation
Star-Sapphire, Emerald and Topaz dishwashers with CrystalDry, plus Masterpiece and Professional hoods, downdraft vents and custom blower inserts. Pumps, spray arms, blower motors and controls — we cover them all.
Thermador Complaints We're Called For
Across the whole lineup, these are the Thermador-specific issues Castle Rock homeowners phone us about week after week:
- Star Burner clicking without lighting, or an ExtraLow simmer that won't hold at altitude
- Freedom Induction cooktop flashing an error, not detecting cookware, or shutting itself off
- Freedom Collection column drifting warm on one side while the other stays perfect
- Diamond ice maker turning out hollow, cloudy or slushy cubes — or nothing at all
- Convection oven browning unevenly or reading well off its set temperature
- Sapphire dishwasher leaving standing water, wet plastics, or a chalky mineral film
- SoftClose oven door dropping shut hard or no longer sitting flush against the seal
- Professional hood blower roaring, barely pulling air, or dead on one fan speed
Why Castle Rock's Altitude and Water Matter to a Thermador
Two things about the Front Range quietly change how a Thermador behaves, and both are easy to miss if you don't work here every day.
At roughly 6,200 feet the air holds less oxygen, so every gas flame burns leaner than the factory jetting assumes. On a Star Burner that shows up as a lazy, yellow-tipped flame, an ExtraLow simmer that starves and dies, or a gas oven that preheats slowly and trips its safety valve. The correct fix is almost never a new burner — it's matching the regulator, orifices and low-flame stop to altitude, which a sea-level technician routinely overlooks.
Front Range water is mineral-heavy, and Thermador's water-fed systems feel it. Scale clogs the Diamond ice maker's fill valve and mold, narrows a dishwasher's spray-arm jets, and crusts up refrigerator water lines and steam-oven reservoirs. We descale, replace the parts the minerals have genuinely ruined, and give honest filtration advice. Colorado's dry air adds a third wrinkle, hardening door gaskets faster than any Thermador manual admits.
Why Choose an Independent Thermador Specialist
Independent doesn't mean unqualified — it means you get depth without the dealership overhead.
Because we aren't tied to a manufacturer's dispatch queue, we schedule around your kitchen instead of a corporate calendar, and we're candid when a repair is or isn't worth it. Thermador appliances are engineered to run well past a decade, and most failures are individual parts — an igniter, a fan motor, a control board, a gasket, a pump — rather than the sealed system or the whole machine.
That focus pays off on the diagnosis. Knowing that a Freedom Induction 'dead zone' usually traces to one coil or its sensor rather than the whole board, or that a warm column is far more often a defrost or damper fault than a failed compressor, is the difference between a targeted repair and a needless four-figure invoice. We verify the fault before we quote it, then fix it with the correct factory-specified part for your exact model.
The mistake we're called in to undo most often is a good Thermador part replaced because nobody diagnosed the real fault. On these appliances, confirming what's actually wrong before quoting the fix is the whole job.

Frequently Asked Questions
Which Thermador appliances do you actually work on?
All the major categories: Pro Grand and Pro Harmony ranges, Masterpiece and Freedom Induction cooktops, Masterpiece and Professional wall and steam ovens, Freedom Collection columns and French-door refrigerators, Star-Sapphire and Emerald dishwashers, and Masterpiece and Professional hoods and downdraft ventilation. If you're unsure about your model, call (303) 801-0060 and we'll confirm.
Are you affiliated with or authorized by Thermador?
No. We're an independent premium-appliance repair company and are not affiliated with or authorized by Thermador or any manufacturer. We specialize in the brand and fit OEM-quality, factory-specified parts, which lets us keep pricing fair and scheduling flexible.
My Thermador is out of warranty. Can you still service it?
Yes — most of our Thermador work is on out-of-warranty appliances. Because these units are built to last well past a decade, a correct repair with factory-specified parts is almost always a better value than replacement. We'll tell you honestly if a unit isn't worth fixing.
Why does my Thermador struggle more than my old range did at this altitude?
Thermador's high-output Star Burners and precise ExtraLow simmer are more sensitive to lean, high-altitude combustion than a basic burner, so miscalibration is more noticeable. Matching the regulator, orifices and low-flame setting to 6,200 feet restores clean flame and a stable simmer — something we do on site.
How soon can a technician come out?
We answer the phone 24/7 and run repair visits daily from 8:00 AM to 6:00 PM, typically same-day or next-day across Castle Rock, Castle Pines, The Meadows, Founders Village and the rest of Douglas County. Book at (303) 801-0060 or use the Book Online link to reserve a window.

Frost kept building along the frame of the fresh-food door on our 48-inch built-in. The technician showed me the gasket had gone hard and lost its memory, and that the hinge cartridge had sagged just enough to break the seal at the top corner. He replaced both, then spent a few minutes explaining what causes it and what to look for later — a gasket that no longer springs back, or a door that needs a nudge to shut. I appreciated being told rather than just billed.
After our kitchen remodel the hood roared like a jet and still let steam hang over the range. Two technicians before this one told us the blower was tired and quoted a new one; neither of them put an instrument anywhere near it. This company went up into the ceiling, found the duct run had been crushed flat where the remodel crew routed it around a new beam, rebuilt the transition, and then actually measured the airflow at the hood so we could see the difference. It is quieter now and the kitchen clears.
Lettuce freezing solid in the refrigerator while the freezer behaved perfectly — that combination had already earned us a quote for a new control board from another company. Our technician opened it up, found the air damper motor stuck wide open so freezer air poured into the fresh-food section, and replaced the damper for a small fraction of that quote. Honest work.
The heating element in our Thermador warming drawer had gone open circuit, so it was doing nothing but taking up space. What stuck with me as much as the repair was the care taken with the house: floor covering down before anything came out of the cabinet, tools kept on a mat, and the kitchen wiped down before he left. You would not have known anyone had been in.
The lower zone of our wine unit had been running warm for a while, and it turned out to be the compressor start relay — diagnosed properly, repaired in one visit, and the bill came in exactly where they said it would. My one real complaint is getting on the calendar: it took over a week from my first call before anyone could come out here, which is a long time to watch a cabinet of wine sit at the wrong temperature. Four stars for the wait, not for the work.
