Viking Range Error Code 2 flashes

Two flashes on a Viking range indicates an RTD probe fault in the 48-inch left-hand oven and griddle zone. The thermostat control has detected that the oven temperature sensor is either open (broken circuit) or shorted (circuit with near-zero resistance). This prevents the control from accurately reading the oven temperature, which typically disables heating in the affected zone.

The affected oven or griddle zone should not be used while this fault is active, as the control cannot accurately regulate temperature without a functioning RTD probe. Using it in this condition risks overheating or unpredictable temperature behavior. Other burners on the range that are unrelated to the faulted zone may still be safe to use.

Resetting the range by cutting power at the breaker may temporarily clear the fault display, but the error will return as soon as the control re-checks the RTD circuit and detects the same open or short condition. A reset does not repair the underlying problem. The fault will persist until the defective probe, wiring, or control component is actually repaired or replaced.

A knowledgeable DIYer can perform the initial diagnosis by testing the RTD probe resistance with a multimeter at the probe terminals. If the probe reads open or shorted, replacing the RTD probe is a repair many technicians and experienced DIYers can complete. However, if the wiring or control board is involved, professional repair is recommended to avoid further damage.

If only the RTD probe needs replacement, parts typically range from around $50 to $150 depending on the specific model, with professional labor adding $100 to $250 or more depending on your area. If the wiring harness or thermostat control board is also involved, total repair costs can be significantly higher, potentially ranging from $300 to $600 or more.
