Viking Wall Oven F2 Fault Code
F2 on a Viking wall oven indicates the oven temperature sensor (RTD probe) is reading a short circuit — sensor resistance is below the acceptable minimum for the current oven temperature. The ERC interprets this as a dangerously high temperature reading and shuts down the oven as a safety measure. Do not use the wall oven with F2 active — the oven cannot accurately regulate heat. F2 is most commonly caused by a failed RTD probe, which is a straightforward OEM replacement. Replacement with a genuine Viking OEM sensor resolves F2 in the majority of cases.
What Causes the F2 Error?
The resistance temperature detector probe has failed internally with an electrical short, producing a near-zero resistance reading that the ERC interprets as an impossibly high temperature.
The wiring between the RTD probe and the ERC has developed a short — typically from the harness chafing against the oven cavity wall or rear panel during a service event.
Steam or condensate inside the sensor connector has created a conductive bridge between the signal terminals, simulating a shorted probe element.
Extended high-temperature oven use has degraded the sensor wiring insulation, causing the two signal conductors to contact each other and create a short-circuit condition.
Basic Steps Before Calling a Technician
-
01Reset the Wall Oven
Switch off the wall oven circuit breaker for 60 seconds, then restore power. If F2 does not immediately return, monitor the oven through one complete bake cycle to confirm the fault has cleared.
-
02Do Not Use the Oven Until Repaired
F2 means the oven cannot accurately read or regulate its own temperature. Operating the wall oven with an unresolved F2 fault risks overheating the oven cavity and damaging food and internal components.
-
03Locate and Inspect the RTD Probe
With power off and the oven cooled, inspect the RTD probe at the back of the oven cavity for visible damage or corrosion. Check the probe connector for moisture or contamination. Report your observations to your technician to assist in diagnosis.
When to Call a Technician
F2 codes that return after a breaker reset require professional RTD probe diagnosis. Our technician tests sensor resistance with a calibrated multimeter and replaces the probe with a genuine Viking OEM part matched to your wall oven model series.

Viking F2 Error Code — Frequently Asked Questions
Common questions about Viking appliance repair answered by our certified technicians.
-
No. F2 means the temperature sensor is shorted and the oven cannot regulate heat accurately. Using the oven with an active F2 fault risks overheating the cavity. Do not use the wall oven until the RTD probe has been replaced by a certified technician.
-
F2 indicates the RTD sensor is reading a short circuit — resistance too low, indicating an impossibly high temperature. F3 indicates an open circuit — resistance too high or infinite, indicating the sensor is broken or disconnected. Both prevent oven operation as safety measures, and both are resolved by replacing the RTD probe or its wiring.
-
A technician will test the probe resistance with a multimeter. A functional Viking RTD probe reads approximately 1,090–1,100 ohms at 70°F room temperature. A reading near zero ohms confirms the probe is shorted (F2); a reading of infinite resistance confirms the probe is open (F3). Both conditions require OEM probe replacement.
