Viking Range F3 Fault Code
F3 on a Viking range or wall oven indicates the oven temperature sensor (RTD probe) circuit is open — either the probe itself has broken internally or its wiring connector is disconnected. Like F2, F3 causes the ERC to shut down oven operation. F3 and F2 are diagnosed identically; the technician tests sensor resistance to confirm whether the probe, connector, or wiring is the cause.
What Causes the F3 Error?
The sensor probe element has broken internally, reading infinite resistance. Replace with a Viking OEM probe.
The wiring connector at the sensor or ERC has come loose. Our technician checks and reseats connectors before replacing parts.
Basic Steps Before Calling a Technician
-
01Reset the Oven
Switch off the breaker for 60 seconds. If F3 does not return, monitor for recurrence.
When to Call a Technician
F3 requires professional sensor diagnosis. Our technician measures sensor resistance to confirm the failure before ordering parts.
