Thermador has a long list of firsts: the residential wall oven, the first downdraft cooktop, and the Star Burner, a five-pointed burner with 56 ports that spreads the flame more evenly than a round one. That ambition shows up across the line. CrystalDry dishwashers use a natural mineral called zeolite to pull moisture from the air, Freedom refrigerator columns ride on SoftClose hinges, and the steam ovens run on calibrated boilers. These are well-built machines that are worth fixing right.
That same design means a Thermador needs someone who knows it. Star Burner ports clog differently than a standard burner, so all 56 openings get cleaned by hand. CrystalDry cartridges wear out and need replacing every few years, which catches most owners by surprise. Steam oven boilers need descaling with the right solution on a set schedule. FixitBay LLC services Thermador units across San Francisco, the Peninsula, and Marin County, and we understand each of these systems at the component level.

Who repairs Thermador appliances in San Francisco?
FixitBay LLC repairs Thermador ranges, cooktops, wall ovens, refrigerators and dishwashers for homes across San Francisco, the Peninsula and Marin, working under California license BHGS #51001. Thermador is premium built-in equipment, its star burners and column refrigeration built to last, so a proper repair is worth far more than a swap-out. Parts specific to your model and serial get quoted before you approve any work. The diagnostic runs $80 and credits toward the repair, always after a written estimate. Every job carries a 180-day warranty on parts and labor. Book same-day or next-day, and the calendar shows the earliest window.
Do you repair Thermador dishwashers?
Yes. Sapphire dishwashers (DWHD440MFM, DWHD650JFP) and the Emerald line are regular Thermador work for us. Most calls are one of three things: an E24 code because the machine cannot drain, an E15 code because the leak sensor found water in the base pan, or a door that no longer seals and drips onto the floor. The Sapphire shares its sump module with the Bosch 800 Series, so the parts that fail most often, the drain pump and the water inlet valve, come through the BSH network in about 2-4 days. A Thermador dishwasher repair runs from $315 including parts and labor. On a CrystalDry model the zeolite cartridge loses capacity after roughly 3-5 years and dishes start coming out damp; a new cartridge is priced in the same band. Where the machine will come out without disturbing your custom panel, that is how we take it out. You approve a written estimate first, the $80 diagnostic is credited to the repair, parts and labor carry a 180-day warranty, and we cover San Francisco, the Peninsula and Marin with same-day or next-day visits.
Do you repair Thermador cooktops and stove tops?
Yes. Thermador Star Burner gas cooktops (SGSX305, SGSX365) and the Freedom induction tops (CIT304, CIT365) are both regular work for us. On a Star Burner the usual call is one burner that will not spark: a cap knocked out of line, a sooted electrode, or on a front burner a worn switch. We line the caps up and test the electrode first, because that often fixes it with no parts, and replace the spark module only when the test says so; a Star Burner cooktop repair for the spark or switch starts from $495. On an induction top a dead zone is usually the generator board or a thermal sensor, from $495. The glass is bonded to the frame, so we lift it with suction tools and fit a fresh bonding gasket on the way back. Thermador-only parts are ordered against your serial number, and we quote the lead time before you approve. The $80 diagnostic is credited to the repair, parts and labor carry a 180-day warranty, and we cover San Francisco, the Peninsula and Marin with same-day or next-day visits.
Do you repair Thermador ranges and stoves?
Yes. Pro and Pro Grand ranges and stoves (PRG486, PRD486, PRG304) are the Thermador we see most. When one burner will not light it is the electrode in the center of the star, the spark module, or a worn switch on a front burner you use a lot, and we test the part before replacing it. A Pro range repair for the Star Burner igniter or spark module starts from $495. Most of these finish the same day when the part is on hand; Thermador-only parts are ordered against your serial number and take longer, and the return visit carries no second trip fee. A Pro Grand is worth repairing well into its 12 to 16 year range against a replacement that starts near $11,000 installed, and we give you the real numbers at the visit. The $80 diagnostic is credited to the repair, parts and labor carry a 180-day warranty, and we book same-day or next-day across San Francisco, the Peninsula and Marin.
Do you repair Thermador refrigerators and freezers?
Yes. Freedom Collection built-ins (T18, T36, T48) come to us most around year 9 to 13, when the fresh-food side runs warm. We check the low-cost causes first, dusty condenser coils, then a tired evaporator fan, then a weak compressor capacitor, and we test before replacing anything. We work around your cabinet trim, not through it. We service the Freedom Collection freezer and wine columns as well. A Freedom Collection refrigerator service starts from $495, and on a 13-year-old fridge it buys another 4 to 6 years against a replacement that starts near $12,000 once the cabinetry is refit and the power and water reconnected. Freedom Collection control boards are Thermador-only parts, ordered against your serial number; we give you the lead time when we quote, and the return visit carries no second trip fee. The $80 diagnostic is credited to the repair, parts and labor carry a 180-day warranty, and we cover San Francisco, the Peninsula and Marin with same-day or next-day visits.
Do you repair Thermador ovens?
Yes. Masterpiece wall ovens (MEDS302, MEDMC301), the steam models, and the oven in a Pro or Pro Grand range all come to us. As a Masterpiece ages it usually shows one of two faults: a convection fan that stops, which you notice as uneven baking and no fan sound on preheat, or a steam system that weakens or throws a descale error. The fan job takes about 90 minutes and the steam generator closer to 2 to 3 hours, and we do both from the front wherever the trim allows it. We test an oven that will not heat in a fixed order: the bake or broil element, the igniter on a gas model, then the control board. A Thermador oven repair on a Masterpiece wall oven runs from $495, depending on which part failed and how the unit is trimmed into the cabinetry. You get a written estimate before anything is ordered, the $80 diagnostic is credited to the repair, parts and labor carry a 180-day warranty, and we cover San Francisco, the Peninsula and Marin with same-day or next-day visits.
Why is my Thermador oven not heating?
Usually a failed bake or broil element, a weak igniter on gas models, or a control board that stopped sending the heat signal. We test in that order, because the first two are the common, cheap failures and the board is neither. An element that has burned through often shows a blister or a visible break; an igniter that glows but never opens the gas valve has drifted out of spec and has to be measured, not eyeballed. On a Masterpiece wall oven the repair lands from $495 depending on which part failed and how the unit is trimmed into the cabinetry. A Pro range igniter and spark job runs from $495. You get a written estimate before anything is ordered, the $80 diagnostic comes off it, and the work carries a 180-day warranty.
Why is my Thermador refrigerator not cooling?
On a Freedom Collection built-in the order of suspects is dusty condenser coils, then a tired evaporator fan, then a weak compressor capacitor. We clean the coils and rule out the simple causes before quoting a single part, because a coil packed with dust makes a healthy compressor behave like a dying one. If the fan is the problem you usually hear it before you feel it: a ticking or grinding from the freezer side. Freedom Collection service runs from $495 depending on which of the three it turns out to be, with a coil cleaning sitting at the bottom of that band. If the sealed system is at fault we tell you, instead of replacing parts around it. The $80 diagnostic is credited toward whatever you approve.
My Thermador dishwasher shows an E15 or E24 error. What does it mean?
E15 means the leak sensor found water in the base pan. E24 means the machine cannot drain. They are different problems, and neither is a reason to keep running the cycle. For E15 we find where the water came from, usually the sump gasket, the door seal, or a cracked hose, and dry the pan before resetting the sensor, because clearing the code without finding the leak only postpones it. For E24 the culprit is a clogged filter, a blocked drain hose, or a drain pump that has lost its impeller. A Sapphire dishwasher repair runs from $315 including parts and labor, and plenty of E24 calls end with a filter clean and no parts at all. The $80 diagnostic comes off the total.
Is Thermador the same as Bosch?
They are siblings, not the same brand. Both belong to BSH Hausgerate, the Munich group, where Thermador is the American premium flagship and Bosch the mid-tier line. They share a substantial parts catalogue: sump modules, drain pumps, water inlet valves, and induction thermal sensors move between them, which is why a Sapphire dishwasher and a Bosch 800 Series can take the same drain pump. What does not transfer is the premium hardware. Star Burner spark modules, Freedom Collection control boards, and Masterpiece oven controls are Thermador-specific and priced accordingly. The practical effect is that a shared part reaches us in about 2-4 days while a flagship part takes longer, and we give you the date once we know which. We tell you which category yours falls into before you commit to anything.
Why is my Thermador Star Burner not sparking on one burner?
Three causes, in the order we check them. First, a burner cap nudged out of alignment during cleaning, which needs no parts and accounts for more of these calls than owners expect. Second, a worn electrode on that one burner, which sparks weakly or not at all while its neighbours behave normally. Third, a spark module beginning to fail, in which case the fault usually migrates around the cooktop instead of staying put. We line up the cap and clean the electrode before quoting a part, because a no-parts fix is still the right answer when it is the right answer. When parts are needed, a Star Burner cooktop repair runs from $495. The $80 diagnostic is credited toward it, and the work carries a 180-day warranty.
How long do Thermador appliances last?
By line: Pro and Pro Grand ranges run 16 to 22 years. Freedom Collection built-in refrigerators go 16 to 20. Masterpiece wall ovens land at 14 to 20, and Sapphire dishwashers at 12 to 16. The built-in lines reach the upper end because the cabinetry shelters them and because owners of built-ins service them. What pulls the numbers down is predictable: condenser coils nobody cleans, a sump filter left to clog until the drain pump gives up, an oven hinge that has sagged and lets heat cycle the control board. None of that is expensive to catch early. For a specific unit, one visit tells us more than any table can, and the $80 diagnostic is credited toward whatever repair you approve.
Should I repair my 14-year-old Thermador Pro Grand?
Almost always yes, because the replacement side of the ledger is ugly. A comparable Pro Grand runs from $11,000 once you count the range, delivery, refitting the built-in cabinetry, and the gas work. A spark module and burner switch service on a 14-year-old Pro Grand is a repair from $495 and typically returns 5 to 8 years of use. Thermador engineers these ranges for 16 to 22 years, so 14 is not the end of the story. The calculus changes when the control board, the valves, and the burners all fail within a season on a range past 20 years, and at that point we tell you to stop spending. You get that assessment in writing at the visit, and the $80 comes off whatever you decide.
Do you handle Thermador Freedom Collection installations?
Yes, we work on every unit in the line: the T18, T24, T30, T36, T42, and T48 Series Freedom Collection built-in refrigerators, freezers, and integrated drawer units. Built-in access is the part most technicians underestimate. Where the unit will come out without disturbing the trim or your custom panel, that is how we do it, and most jobs go that way. Some models are tighter: the trim and the top grille have to come away first, and on a few the shims left by the cabinet installer sit exactly where a service panel needs to open. That part is cabinet work rather than appliance work, so it is done by whoever fitted your kitchen. Arrange it before our return visit and we pick the repair straight up from there. Service on a Freedom Collection unit runs from $495 depending on the fault. The $80 diagnostic covers the visit and is credited toward the repair once you approve the written estimate.
Do you carry Thermador parts in stock?
Not usually. Thermador components come through the BSH network, ordered against your model and serial number after the diagnostic has identified the fault. Delivery runs longer than the 2-4 days a mass market part takes, and we give you the date once we know the part, not before. If the component is one we happen to have on hand, we finish the repair the same day you approve the estimate. The return visit carries no second diagnostic and no charge for the trip. Where Thermador has discontinued a part with no equivalent, we tell you upfront what the alternative costs. A written estimate comes before we order anything, and the number does not change afterward.
Are you licensed to repair Thermador appliances?
Yes. FixitBay LLC is a Licensed Major Appliance Technician under California License #51001, issued by the Bureau of Household Goods and Services and valid through July 31, 2027. We are independent technicians rather than a Thermador factory branch, and we do not pretend otherwise. The license number is printed on your invoice, next to the 180-day warranty on parts and labor, and the Bureau publishes a lookup if you want to verify it yourself. We carry insurance. Gas ranges and cooktops get the extra care they warrant: we leak-check every joint we open and will not leave an appliance in service if a connection does not hold.
What is CrystalDry and when does it need replacing?
CrystalDry uses zeolite, a natural mineral that pulls moisture out of the air at the end of the cycle and releases it as heat, which is how the dishwasher dries plastics without a heating element. The mineral is not consumed the way a filter is, but after roughly 3-5 years of regular use its absorptive capacity falls and dishes start coming out damp. Replacing the cartridge restores it. We swap the unit, run a full cycle, and confirm the drying performance before we leave, instead of taking your word for it a week later. On a Sapphire this sits inside the dishwasher band from $315. If your dishes are wet for a different reason, usually a rinse-aid setting or an overloaded top rack, we will tell you that instead.
Is Thermador repair more expensive than standard brands?
Yes, and the reason is the parts, not the labor. Thermador uses OEM components with no third-party equivalent worth fitting: a Star Burner spark module or a Freedom Collection control board costs several times its Bosch counterpart. What that comparison leaves out is the other side of the ledger. Replacing a Thermador appliance runs from $5,000 and a built-in replacement drags the cabinetry along with it. Against that, a range repair from $495 or a dishwasher repair from $315 is not a close call. We quote before we work, and where a repair does not make financial sense we tell you and describe what replacement would involve. The $80 diagnostic is credited toward any work you approve.
My Thermador steam oven keeps showing a descale alert. How is that fixed?
We flush the steam generator with a commercial descaling solution, clear the mineral deposits out of the internal passages, and reset the descale counter in the control board. The alert is a counter, not a measurement, so resetting it without descaling hides the problem until the passages narrow enough to trip a real fault. Bay Area water is hard enough that the interval matters: descale when the machine asks, not when it stops working. If the generator has scaled shut and cannot be recovered, it gets replaced, and we tell you which of the two you are facing before you approve anything. A written estimate comes first either way, the $80 diagnostic is credited toward the work, and the repair carries a 180-day warranty on parts and labor.

On Thermador Star Burner ranges (Pro and Pro Grand: PRG486, PRD486, PRG304), a small electrode sits in the center of each star. When one burner will not spark, it is usually that electrode, the spark module, or a worn switch on a front burner you use a lot. We test the part before replacing it, and most of these are done the same day when the part is on hand.
Freedom Collection built-ins (T18, T36, T48) act up like most premium fridges. Around year 9 to 13, a warm fresh-food side usually comes down to dusty coils first, then a tired evaporator fan, then a weak compressor capacitor. We check the simple, low-cost causes first, and we work around your cabinet trim rather than through it.
Thermador Sapphire dishwashers use the same internals as the Bosch 800 Series, so drain problems are easy to pin down. About half the time the sump filter just needs a good cleaning, and we will show you how to do it each month. The rest is usually the drain pump or a kinked hose. Where the machine will come out without disturbing your panel, that is how we take it out.
Masterpiece wall ovens (MEDS302, MEDMC301) usually show two issues as they age: a convection fan that stops (uneven baking, no fan sound on preheat) or a steam system that weakens or throws a descale error. The fan takes about 90 minutes; the steam generator is closer to 2 to 3 hours. We do both from the front wherever the trim allows it.
Star Burner cooktops (SGSX305, SGSX365) often stop sparking for simple reasons, like a cap knocked out of place during cleaning or a sooty electrode, long before a real part fails. We start by lining the caps back up, which usually fixes it with no parts at all. Good ignition on these comes down to getting that alignment right.
When one zone goes dead on a Thermador induction top (CIT304, CIT365 Freedom), it is usually the generator board or a thermal sensor, and we can replace either one. The glass is bonded to the frame, so we lift it with suction tools and fit a fresh bonding gasket when we put it back, so the seal stays tight.
The useful thing about Thermador's BSH parentage is what it does to a repair. Where a Thermador uses hardware it shares with the Bosch 800 Series, a Sapphire dishwasher sump or an induction sensor, the part is common and reaches us quickly. Where it uses its own flagship hardware, a Star Burner spark module or a Freedom Collection control board, the part is Thermador-specific and ordered. We diagnose which of the two a fault needs before quoting, because the answer changes both the price and the timeline.
That split runs the parts side of every Thermador job. The Bosch-shared components come through the BSH network in about 2-4 days, and where one is on hand the repair finishes sooner. The Thermador-only parts, the Star Burner, Freedom Collection, and Masterpiece assemblies, are ordered against your serial number and take longer, and a few of the oldest ship from Europe and take longer still. We give you the timeline when we quote, and the return visit carries no second trip fee for the wait.
On the economics, Thermador favours repair well into the 12 to 16 year range, and the cabinet work is what makes it so. A Freedom Collection refrigerator service from $495 on a 13-year-old unit buys another 4 to 6 years against a replacement that starts near $12,000 once the cabinetry is refit and the power and water reconnected. A Pro Grand range tells the same story: a spark module and burner switch from $495 against a replacement that starts near $11,000 installed. We give you the real numbers at the visit.
Thermador is the American flagship of BSH Hausgeräte, the Munich group that also builds Bosch in the States and Gaggenau, Siemens, and Neff in Europe. In the US, BSH concentrates on Thermador and Bosch, and the two are engineered close enough that a Sapphire dishwasher and a Bosch 800 Series can take the same sump module. That is why Thermador sits where it does: German BSH mechanicals under an American premium finish, with the Star Burner range and Freedom Collection refrigeration as its own signatures.
For service, that parentage cuts both ways. The shared BSH hardware means the common failures on a Thermador are the same ones we already solve on Bosch, with the same procedure and the same diagnostic tools. The flagship hardware, the Star Burner ignition, the Freedom Collection controls, the Masterpiece steam, needs its own steps and its own patience. It is a premium line that rewards a technician who knows both the Bosch platform underneath and the Thermador-specific access on top.
For an owner, the built-in design is the whole repair-versus-replace story. A Freedom Collection refrigerator or a Pro Grand range is trimmed into the cabinetry, so replacing one is never just the appliance, it is the cabinet refit and the reconnection that come with it. That is why these units are built to be serviced for well over a decade and why repair stays the sensible call deep into their life. We give you the specific numbers for your unit at the visit.
