What Thermador appliances do we repair in Chicago?

Thermador has defined the premium home kitchen appliance category for decades — built on European engineering, professional-grade performance, and features like the signature Star Burner and ExtraLow simmering system that are genuinely different from any other brand on the market.

At IVAN Appliance Repairs, we service the full Thermador lineup across Chicago, Evanston, Oak Park, Elmwood Park, and surrounding suburbs. Because Thermador appliances use proprietary technology that differs significantly from mainstream brands, our technicians approach every Thermador repair with brand-specific knowledge.

‍

What Thermador range, oven, and cooktop problems do we fix?

Thermador ranges and wall ovens — including Pro Grand, Professional, and Masterpiece series — are found in high-end kitchens throughout Evanston and Chicago’s North Shore. Thermador cooktops, including gas, induction, and dual-fuel models, use proprietary burner systems that require brand-specific parts and knowledge to repair correctly. Our oven and range repair technicians diagnose and fix:

Thermador oven not heating or not reaching set temperature — sensor, element, or igniter fault
Star Burner clicking with no ignition — moisture around igniter tips or spark module failure
ExtraLow simmer burner not holding low flame — specialty valve replacement
Oven door locked after self-clean cycle — E118 / E119 latch motor fault
Convection fan failure — uneven baking or roasting results
Error codes: E010, E011 (temperature sensor), E032 (cooling fan), E118, E119 (door latch), E501 (cooktop communication)

Dishwasher not draining or E24 drain fault code
Door latch not sealing or dishwasher not starting

What makes Thermador different from other premium brands we repair?

Three Thermador-specific technologies set it apart from Viking, Bosch, and mainstream brands — and all three affect how we diagnose and repair faults:

The Star Burner — Thermador’s five-point star-shaped gas burner distributes flame more evenly than a standard round burner and produces 18,000 BTU at maximum output. The five tips are more exposed to moisture than a conventional burner, which is why Star Burner clicking after cleaning is a specific complaint we see regularly on Chicago service calls. The igniter tips and spark module for this burner are Thermador-specific parts.

ExtraLow simmering — Thermador’s ExtraLow burners use a pulsing valve to maintain temperatures as low as 100°F without going out — lower than any mainstream residential burner. When the ExtraLow valve weakens, the burner either won’t hold the simmer or the flame extinguishes at low settings. A standard gas valve will not replicate this function. Only the correct Thermador ExtraLow valve restores it.

Home Connect — Thermador’s smart platform allows remote monitoring and diagnostics via the Home Connect app. When a fault code appears on a Home Connect-enabled appliance, the diagnostic data is often already in the app before the homeowner calls us. We use this data as part of the diagnosis on connected models.

Common Thermador error codes and fault signs — what they mean

Thermador appliances use alphanumeric fault codes on their digital displays to flag specific issues. Here are the most common ones we diagnose on Chicago, Evanston, and Oak Park service calls:

E118 / E119 — Oven door latch fault during or after self-clean cycle. The latch motor is not confirming the door is locked or unlocked. Do not force the door — call us. This is one of the most common Thermador oven calls we receive.
E010 / E011 — Oven temperature sensor open or shorted. The oven cannot regulate heat until the sensor is replaced. Baking results will be unreliable or the oven will not heat at all.
E032 — Oven cooling fan fault. The cooling fan has stopped running, which can cause overheating of the control electronics. Stop using the oven and call for service.
E501 / E502 — Induction or gas cooktop communication fault between the cooking zone and the control board. One or more burners may be unresponsive.
Star Burner clicking with no ignition — Thermador’s five-point Star Burner design is prone to moisture trapping around the igniter tips after heavy cooking or cleaning. This clears with careful drying in most cases, but if clicking persists after 24 hours the igniter or spark module needs to be replaced.
E24 on dishwasher — Drain fault. Check the filter and drain hose for blockage. If the code returns after clearing the filter, the drain pump needs to be replaced.

If any Thermador error code returns after a reset, the underlying component needs to be diagnosed and replaced. A reset clears the display — it does not fix the part.

Frequently asked questions — Thermador appliance repair in Chicago

How much does Thermador appliance repair cost in Chicago?

Most Thermador appliance repairs in the Chicago area range from $220 to $600 depending on the appliance and the part required. Thermador is one of the premium European-engineered brands and parts cost more than mainstream brands, but repair is still significantly less expensive than replacing a Thermador wall oven, range, or refrigerator. We provide a clear written estimate before any work begins.

My Thermador range Star Burner keeps clicking — is that a fault?

Yes. Thermador’s Star Burner — the five-point star-shaped burner used across most Thermador gas ranges and cooktops — is designed to distribute flame more evenly than a standard round burner, but the five tips are more exposed to moisture and food debris than a conventional burner design. After heavy cooking or cleaning, moisture can collect around the igniter tips and cause persistent clicking. In most cases this clears after the burner area dries completely. If clicking continues after 24 hours, the igniter or spark module needs to be replaced.

My Thermador oven is showing E118 or E119 after a self-clean cycle — what do I do?

E118 or E119 on a Thermador oven means the door latch motor cannot confirm whether the door is locked or unlocked, usually after a self-clean cycle. Do not try to force the door open — the latch mechanism can be damaged permanently. Call us and we will release the latch safely, diagnose whether the motor or the latch assembly needs replacement, and restore normal operation. This is one of the most common Thermador oven repairs we handle in Chicago and Evanston.

Do you repair Thermador dishwashers with StarDry technology?

Yes. We service all Thermador dishwasher models including the Thermador Star Sapphire series and the Thermador Emerald series with the signature StarDry zeolite drying system. StarDry faults typically present as dishes that come out wet despite a full cycle, and usually point to a zeolite drawer or fan motor issue that we can diagnose and repair in a single visit.

Do you offer same-day Thermador appliance repair in Chicago and Evanston?

Yes. We offer same-day service in Chicago, Evanston, Oak Park, Elmwood Park, and most surrounding suburbs. Call (630) 214-1998 or book online and we will confirm your appointment quickly.

Is it worth repairing a Thermador appliance?

Thermador appliances are built on a premium European-engineered platform and are almost always worth repairing if they are under 15 years old and the repair cost is less than 50% of replacement value — which on Thermador ranges and wall ovens is a very high bar to reach. Well-maintained Thermador appliances regularly exceed 15 years of reliable service. Our technicians give honest advice on whether a specific repair makes financial sense.

My Thermador ExtraLow burner won’t hold a simmer — what causes that?

Thermador’s ExtraLow simmering burners use a special valve that cycles the flame on and off rapidly to maintain very low temperatures without extinguishing the flame entirely. If this valve weakens or fails, the burner either won’t hold a simmer or the flame keeps going out at low settings. This is a Thermador-specific repair that requires the correct replacement valve for your model — a generic valve will not replicate the ExtraLow function.

Do you also repair Thermador refrigerators?

Yes. We service Thermador refrigerators, including column refrigerators and freezers and Freedom induction refrigerator models. Common issues include cooling faults, ice maker failures, and control board communication errors. We approach Thermador refrigerator repairs with the same brand-specific knowledge we bring to Thermador’s cooking appliances.
