Thermador Range Error Code F153

F153 on a Thermador range signals that either the control calibration values have gone outside their acceptable range or the User Interface board has detected an overtemperature condition. The Power Board monitors both of these parameters and triggers this fault when either falls outside safe limits. The error causes the range to interrupt normal operation until the issue is resolved.

It is not advisable to continue using the range while F153 is active. The error indicates either bad control data or an overheating condition in the control electronics, and operating the range in this state could allow the problem to worsen or create additional component damage. The range should be left off until the fault is diagnosed and cleared.

Repair costs vary depending on what component is at fault. If only a re-calibration or connector reseating is needed, costs would primarily cover a service call, typically in the range of $100 to $200. If the Power Board requires replacement, parts and labor combined can range from $300 to $600 or more, depending on your location and service provider.

Some cases of F153 can be resolved by performing a re-calibration through the control panel if that option is accessible. Beyond that, fixing the fault involves inspecting connector P1B and its wiring harness for damage or loose connections, which requires accessing the interior of the range. If the boards themselves are at fault, replacing a Power Board is a task best handled by someone comfortable working with appliance electronics and internal wiring.

A power reset, such as turning off the circuit breaker for 30 to 60 seconds, may temporarily clear the F153 code if the fault was triggered by a transient event like a power fluctuation. However, if the underlying cause is a hardware problem such as a bad connector, damaged wiring, or a failing Power Board, the code will return. Re-calibration is a more targeted first step than a simple reset for this particular fault.
