Yes, we repair Thermador appliances throughout Union City, CA (94587) and the wider Tri-City. As an independent, diagnosis-first bench, we service Thermador gas and dual-fuel ranges, Star-burner and induction cooktops, wall and steam ovens, and Thermador built-in refrigeration. We pin down the real fault first, then fit the genuine OEM Thermador part the job calls for, charge a flat $89 service call that comes off the bill the moment you book the repair, and stand behind every labor job for a full 365 days.
Thermador kitchens in Union City tend to be family workhorses, often a mix of newer Masterpiece and Professional units alongside older built-ins that have cooked through a decade of weeknight dinners. We meet each one where it is: a careful read of what the appliance is actually doing, and when a part sits on the fence we say so and lay out repair versus replace in plain numbers, with nothing padded onto the ticket.
Because Union City sits on our combined Fremont and Hayward route, we reach Decoto, Alvarado, Old Alvarado and the Union City hills without adding a far-trip surcharge, and a next-day slot is usually available. Call (650) 668-1554 or Book online to get on the schedule.
Thermador appliances we repair in Union City
From the cooktop to the refrigerator column, we work across the full Thermador lineup that shows up in Tri-City homes. Many calls start with one symptom and turn out to be a simple, well-understood Thermador part — which is exactly why we diagnose before we quote.
Whether your unit is a Professional Pro Grand range from the Alvarado area or a Masterpiece induction cooktop up in the Union City hills, we bring factory-grade tools and follow Thermador service specifications so the right repair goes in the first time.
- Gas, dual-fuel and all-gas ranges (Pro Harmony and Pro Grand families)
- Star-burner gas cooktops, including the low-simmer ExtraLow burners
- Induction and electric cooktops with Liberty or Freedom-style controls
- Wall ovens, double ovens and Thermador steam and combination-steam ovens
- Thermador built-in and column refrigeration, freezer columns and fresh-food units
- Warming drawers, ventilation and pro-style range hoods paired with the cooktop
Cooktop faults: spark modules, igniters and burners
The single most common Thermador cooktop call near me in Union City is a burner that clicks but will not light, or one that lights while every other burner sparks at the same time. On Thermador Star-burner cooktops that points squarely at the spark module, the igniter electrode, or moisture and spilled food bridging the igniter. We clean, test continuity, and replace the spark module or igniter with a genuine OEM Thermador part rather than guessing.
Weak flames, a burner that will not hold a low ExtraLow simmer, or yellow tipping usually trace back to a clogged burner port, a worn burner cap, or a gas-pressure issue at the regulator. On induction models, an error code, a zone that will not recognize a pan, or a cooktop that shuts off mid-cook typically means a control board, a coil, or a thermal sensor — which we confirm electrically before any part is ordered.
Ranges, wall ovens and steam ovens
Thermador range and wall-oven repairs cluster around heat and control. A bake or broil element that no longer glows, an oven that runs hot or cold against the probe, slow preheat, or a door that will not lock for self-clean are the patterns we see most. We measure the element, the temperature sensor (RTD), and the relay board so the fix matches the actual failure instead of a parts swap.
Thermador steam and combination-steam ovens add their own service points — descaling needs, water-reservoir and pump faults, clogged steam outlets, and door-seal leaks that throw moisture errors. Convection fan noise, a flickering or dead display, and a control board that drops keypad response are also frequent. We protect surrounding cabinetry pulling built-in ovens out, a detail that matters on the tight Tri-City installs we see across 94587.
Thermador refrigeration: fans, defrost and seals
Thermador built-in and column refrigeration shares many of the same engineering ideas as other premium built-ins, so the failure list is familiar: an evaporator or condenser fan that stalls, a defrost heater or thermostat that lets frost choke the coil, a door gasket that has lost its seal and is sweating or icing the frame, and control-board or sensor faults that report the wrong temperature.
When a column runs warm on one side, frosts over, or short-cycles, we read the sealed system and the electronics with factory-spec diagnostics before talking parts. Compressor and sealed-system work is real money, so we only recommend it once pressure and electrical evidence back it up — and on an older unit we will tell you honestly when replacement is the smarter spend.
Genuine OEM parts and a 365-day labor warranty
Whether the fix is a spark module, an igniter, a burner cap, a bake or broil element, an RTD sensor, a control board, an evaporator fan or a door gasket, we fit genuine OEM Thermador parts so the appliance lights, heats and cools the way Thermador engineered it to. Generic look-alikes have no place in a premium Thermador.
Every labor job is covered by our 365-day warranty, and that flat $89 service call drops off the bill the instant you approve the repair. You get a clear quote up front, manufacturer-recommended procedures on the bench, and no surprise line items.
Independent Thermador service across the Tri-City
We run an independent Tri-City appliance service — not a factory-authorized dealer — and we have spent years on the bench with Thermador cooktops, ranges, ovens and built-in refrigeration. That independence is the point: straight diagnostics, honest repair-or-replace advice, and OEM parts, without a sales script.
Our combined Fremont and Hayward route keeps us close to Union City and the surrounding cities — Fremont, Hayward, Newark and San Leandro — so service stays prompt with no far-trip surcharge.

Reviews
Thermador repair reviews from the Tri-City
Thermador cooktop burner would not light. It was the spark module. Fair quote, no pressure to replace anything else, and the $89 diagnosis came off the final bill.
Thermador double oven was not holding temperature. A sensor and a relay. Independent, genuine OEM parts and a full year on the labor. Very fair.
Thermador built-in column was warm — the fan motor. Fair quote and they covered Hayward on the Tri-City route with no extra trip charge.
FAQ
Frequently asked questions
What Thermador appliances do you repair in Union City?
We repair Thermador ranges, Star-burner cooktops, wall and steam ovens, and Thermador refrigeration. Common jobs are spark modules and igniters, burner and element faults, control boards and sensors, and refrigeration fans, defrost parts and door seals. We diagnose with factory-spec tools and install genuine OEM Thermador parts, then verify performance before we leave, all backed by our 365-day labor warranty.
My Thermador Star burner won’t light — what is wrong?
Usually a spark module, a worn or soiled igniter, or a misaligned burner cap blocking the spark gap. Moisture or food debris around the electrode can also stop ignition. We test the ignition system on site with factory-spec diagnostics and replace only the failed part with a genuine OEM component, rather than swapping the whole assembly, then confirm a clean, even flame.
How much does Thermador repair cost in Union City?
Every Thermador job begins with the $89 service visit, applied to the repair the moment you book it. A spark module or Star-burner igniter is modest; a control board, oven sensor or refrigeration part costs more, and we itemize the range after diagnosis so nothing proceeds until you have agreed the number. Genuine OEM Thermador parts and a full year of labor coverage are included.
Do you use genuine Thermador parts?
Yes — only factory-certified, genuine OEM Thermador parts, installed to manufacturer specifications. OEM igniters, sensors, elements and boards match your model exactly, which protects performance and longevity far better than generic substitutes. We are an independent service, not an authorized dealer, and we stand behind the repair with a 365-day labor warranty on top of those genuine parts.
Do you cover the Tri-City for Thermador?
Yes — we serve Union City, CA 94587 plus Fremont, Hayward, Newark and San Leandro on a single combined Tri-City route. That routing means no far-trip fee and frequently next-day scheduling. Call (650) 668-1554 to book, and we will confirm your model and serial so the technician arrives prepared with the right genuine OEM Thermador parts on board.
Can you fix a Thermador Star burner that lights unevenly?
Yes. Uneven Star-burner ignition is usually a spark module, a worn or soiled igniter, or a misaligned burner cap. We test the ignition system, then clean or replace only the failed part with a genuine OEM component, and confirm an even, reliable flame before we leave. Each repair is covered by our 365-day labor warranty.
