Thermador Across the Kitchen
Thermador is one of the few brands that spans the whole premium kitchen, from the Star burner range and Freedom induction cooktop to steam ovens and full-height column refrigeration. That breadth means the calls we get in Southport vary widely: an oven flashing an F-code during a bake, a star burner that will not light after a spill, a steam oven that stops filling, or a column fridge drifting warm. Because a Thermador oven reports faults through a numbered F-code family, the code is a real head start, but it only narrows the circuit. We still test the sensor, wiring and control board before replacing anything, so you pay for the part that actually failed.
Parts needs and availability are confirmed after model-specific diagnosis. Whether the unit is a decade-old Professional range or a current Masterpiece wall oven, the aim is the same: read the fault accurately, fit the model-specific replacement, and confirm the appliance is back to spec before we leave.

Error and Fault Codes
Thermador ovens and ranges report faults through an F-code family shared across the platform. The code identifies the circuit; the table below shows what each points to and how we confirm the failed part:
| Code | Meaning | What We Check |
|---|---|---|
| F1 | Control-board or runaway fault | Test the board logic and relays, confirm the sensor is not reading out of range |
| F2 | Oven read an over-temperature condition | Verify the sensor and the bake/broil relays, check for a stuck contact |
| F3 | Open temperature sensor (RTD) | Measure sensor resistance and wiring, replace the sensor if open |
| F4 | Shorted temperature sensor | Test for a short in the sensor or harness, replace the failed part |
| F7 | Stuck keypad or membrane fault | Test the touch panel and ribbon, replace the control or panel as needed |
Extralow and the Star
Thermador's Star burner and ExtraLow simmer rely on a clean cap and a healthy igniter. A burner that will not simmer or light is usually a cleaning-and-igniter fix, not a gas-valve or manifold job.
Common Problems We Fix
In Southport the most common Thermador call is an oven throwing an F3 or F4 sensor code, which usually traces to an aging RTD probe rather than the board. We also see star burners that will not catch after a boilover, ExtraLow simmer that has drifted, steam ovens that stop filling because of a clogged inlet or valve, Freedom Induction zones that cut out under a heavy pan, and column refrigerators that drift warm from an evaporator-fan or defrost fault. Each of these has a defined cause we confirm before quoting.
