Viking Oven Error Code F2

F2 on a Viking oven means the control board has detected an open circuit in the RTD temperature sensor probe circuit. The RTD is the component that measures oven cavity temperature, and when its circuit is open, the board cannot read any temperature data. This causes the oven to shut down and display F2 as a safety measure. The probe itself is the most likely cause of this fault.

No, you should not attempt to use the oven while the F2 code is active. The oven cannot monitor its internal temperature without a functioning RTD probe, which means it has no way to regulate or limit heat output. Operating the oven in this condition creates a risk of uncontrolled overheating. The oven should remain off until the sensor circuit is repaired.

If the RTD probe is the cause, the part itself typically costs in the range of $30 to $80 depending on the specific Viking model, and the repair is relatively inexpensive if done as a DIY project. Professional repair labor for a probe replacement generally runs in the range of $100 to $200 total including the part. If the control board is at fault rather than the probe, repair costs increase significantly, with board replacement often falling in the range of $200 to $500 or more for parts and labor.

Many technicians and capable DIYers can resolve an F2 error by replacing the RTD probe, which is typically a straightforward repair involving disconnecting the old probe from inside the oven cavity and connecting the new one. Before purchasing parts, use a multimeter to confirm the probe reads open or infinite resistance at room temperature, which confirms the probe is the failed component. If the probe tests correctly, additional diagnosis of the wiring harness or control board is needed.

Resetting the oven by cutting power at the breaker may temporarily clear the F2 display, but the code will return as soon as the control board attempts to read the RTD sensor again. Because F2 points to an actual hardware fault in the sensor circuit, the underlying problem must be repaired for the code to stay cleared. A reset alone is not a fix.
