Thermador packs a lot of technology into a kitchen: the patented Star burner, the full-surface Freedom Induction cooktop, and column refrigeration that hides behind cabinet panels. That range of engineering means a Thermador fault can be mechanical, like a clogged burner, or electronic, like a sensor throwing a code. We diagnose both, read the appliance's own fault data rather than guessing, and repair to the model's specification.
Models We Service
- Professional and Pro Grand ranges: gas and dual-fuel PRG, PRD and PRL series with Star burners and ExtraLow simmer.
- Cooktops: the Freedom Induction cooktop, Masterpiece induction, and gas Star-burner cooktops.
- Wall ovens: Masterpiece and Professional single, double and steam ovens.
- Freedom column refrigeration: T18, T24, T30 and T36 refrigerator, freezer and wine columns.
- Dishwashers: Sapphire and Star-Sapphire models with the Chef's Tool and StarDry.
Error and Fault Codes
Thermador cooking appliances do display fault codes, and reading them correctly saves a wrong part. The catch is that the exact meaning shifts between model generations, so we always confirm a code against the appliance's own service data. Below are the families you are most likely to see. Freedom column refrigeration is generally diagnosed by symptom rather than a numeric code.
| Code / Symptom | Commonly Indicates | What We Do |
|---|---|---|
F1 / control fault | Control board or a stuck touch key | Test the keypad and board; replace the failed Reddingnent |
F2 / over-temperature | Oven ran hotter than the safe limit | Check the sensor, relay and control for a stuck-on element |
F3 / F4 sensor | Open or shorted oven temperature sensor | Measure the sensor resistance and replace if out of spec |
F7 / stuck key | Touch control or membrane fault | Test and replace the control panel |
| Column refrigerator warm | Evaporator fan, frosted coil, or thermistor | Test that column's airflow and sensor |
Our blog breaks these down further in Thermador F error codes and Thermador refrigerator not cooling.
Freedom Columns Pair Up
Thermador Freedom refrigeration is sold as separate refrigerator and freezer columns that sit side by side. Each has its own sealed system, so when one runs warm the other usually keeps holding, which points the diagnosis at a single column rather than a shared failure.
Common Problems We Fix
- Star burners that will not light, click continuously, or burn unevenly.
- Freedom Induction zones that will not detect a pan or power up.
- Ovens that will not heat, drift off temperature, or throw an F-code.
- Column refrigerators or freezers running warm or frosting over.
- Sapphire dishwashers that will not drain, dry, or complete a cycle.
- Door locks, hinges and control-panel faults.
Maintenance and Guides
Read our Thermador refrigeration guide for column filter and airflow care, and pair it with the general seasonal maintenance guide. If a column is drifting rather than failing, our temperature fluctuation page is a useful companion.

Frequently Asked Questions
What Do Thermador F-Codes Mean?
Thermador cooking appliances display fault codes to flag a specific circuit. An F-code most often points to the oven temperature sensor, a stuck touch key, the door lock, or the control board. The exact meaning varies by model generation, so we confirm the code against the appliance's own service data before replacing a part.
Why Is My Thermador Column Refrigerator Not Cooling?
A Freedom column runs a dedicated sealed system, so a warm column usually means its own evaporator fan, a frosted coil, or a thermistor rather than a whole-unit failure. Because the columns pair, a warm refrigerator column often sits beside a freezer column that is holding fine.
My Thermador Star Burner Will Not Light. What Should I Check?
The star-shaped port can trap food and moisture, so reseat and clean the burner cap and head first. If it clicks but will not catch, the port or cap is usually the issue; if there is no click, the igniter or spark module needs attention.
Can You Repair the Freedom Induction Cooktop?
Yes. We service the Freedom Induction cooktop, including the full-surface coil array, the control board and pan-detection faults. A zone that will not power a pan is often a coil or board issue rather than the whole cooktop.
Do You Service Both Thermador Cooking and Refrigeration?
Yes. We repair Thermador ranges, rangetops, cooktops, wall ovens, Freedom column refrigeration, and Sapphire dishwashers, so a kitchen built around the brand can be handled in a diagnostic visit, with follow-up timing based on parts availability where the parts are on hand.
Do You Use Model-Specific Genuine OEM Parts?
Yes. We source OEM sensors, igniters, boards and sealed-system parts by model and serial, which is important on a brand where control boards and induction electronics are model-specific.
