Thermador Range Error Code F200

The F200 code on a Thermador range indicates a timeout and stop condition that occurred within the control board's production test mode. This is a factory-level diagnostic function, not a standard operational fault. When this code appears on a home-installed unit, it typically signals a problem with the control board itself, such as the board entering test mode incorrectly or failing to complete the test sequence in time.

The F200 code is tied to a production test function rather than a direct safety system like a gas valve or temperature limiter. However, because it indicates abnormal control board behavior, you should avoid relying on the range for normal cooking until the fault is diagnosed and cleared. Discontinue use and consult a qualified technician if the error persists.

Repair costs vary depending on what is needed. A service call and diagnosis alone typically runs in the range of 80 to 150 dollars. If the main control board needs to be replaced, parts and labor combined can range from 300 to 600 dollars or more depending on the specific model and local labor rates. Getting a diagnosis first will help clarify the exact repair needed before committing to parts costs.

The first step is to perform a full power reset by turning off the circuit breaker supplying the range for several minutes, then restoring power. If the F200 code returns after the reset, the issue is likely internal to the control board and will require professional diagnosis. Attempting to repair or replace the control board without technical experience is not recommended.

A power reset by switching off the circuit breaker for a few minutes may clear the F200 code if the control board entered test mode due to a temporary glitch or memory issue. If the code reappears after restoring power, the control board likely has an underlying fault that a simple reset will not resolve, and further diagnosis is needed.
