Thermador Oven Error Code FC

The FC code on a Thermador oven indicates a fault with the signal being sent to or processed by the electronic control board. The control board is the central component that manages all oven functions, and this code means it has detected an abnormal signal condition. The oven displays this code to alert you that something in its control circuitry needs attention.

You should not continue using the oven while the FC code is active. The fault indicates that the control board is receiving or generating abnormal signals, which means the oven may not regulate temperature correctly or respond to controls as expected. Discontinue use until the fault is diagnosed and resolved.

A power reset will clear the FC code if the fault was caused by a transient electrical disturbance such as a power surge or brief outage. However, if the code reappears after the reset, it means the underlying cause is a physical problem with the control board, wiring, or a connected component that a reset cannot fix. In that situation, a service technician needs to inspect the oven to identify and repair the persistent fault.

The first step you can take yourself is to touch OFF on the control panel or shut off power at the circuit breaker, wait at least 3 minutes, and restore power. This reset clears transient faults caused by power fluctuations and costs nothing. If the FC code returns after the reset, the problem is persistent and will require an authorized service technician to diagnose and repair the underlying wiring or control board issue.

Repair costs vary depending on the root cause. If the issue is a simple wiring connector or harness repair, you might expect labor charges in the range of $100 to $250. If the electronic control board itself needs replacement, parts and labor combined can range from $300 to $600 or more depending on the specific oven model. A technician diagnosis visit is typically required before a firm estimate can be provided.
