Thermador Oven Error Code F19

F19 on a Thermador oven indicates a miscellaneous power board error. The power board is responsible for regulating and distributing electrical power throughout the oven. This code signals that the board has detected an internal fault that requires diagnostic attention before the oven can be safely used.

It is not recommended to continue using the oven while F19 is active. A power board fault can affect how the oven controls heating elements and safety systems, which could result in unpredictable behavior or a potential safety hazard. The oven should be powered off until the fault is properly diagnosed and resolved.

Repair costs for an F19 error vary depending on the root cause. If the issue is limited to a wiring connection, the cost may be relatively low, primarily covering a service call in the range of $80 to $150. If the power board requires replacement, parts and labor combined can range from $250 to $600 or more depending on the specific model and labor rates in your area.

Some causes of the F19 error, such as a loose wiring harness connector, can potentially be addressed by a knowledgeable DIYer after disconnecting power to the appliance. However, diagnosing and replacing a failed power board involves working with high-voltage components and requires a good understanding of electrical safety. If you are not experienced with appliance repair, it is recommended to contact a qualified technician.

A reset, performed by turning off the circuit breaker for 30 to 60 seconds and restoring power, may temporarily clear the F19 code. However, if an underlying issue exists with the power board or wiring, the error is likely to return during normal operation. A reset alone is not a repair and should be followed by a thorough inspection.
