Viking Range Error Code Cycle flashing / Clean OFF

This error indicates a fault in the RTD oven probe circuit on the RH oven of Viking 30", 36", and 48" RH range models. The control board has detected that the temperature sensor is either open or shorted, meaning it cannot read a valid oven temperature. As a safety measure, the oven disables itself until the probe or its wiring is repaired or replaced.

The oven will not operate in a normal bake or roast mode when this error is active, as it has shut down due to the loss of temperature feedback. You should not attempt to defeat or bypass this safety lockout. The surface burners on a gas range may still function, but the oven cavity affected by this fault should not be used until the RTD probe circuit has been repaired.

Resetting the range by cycling power may temporarily clear the displayed error, but the fault will return as soon as the control board again attempts to read the RTD probe and receives an invalid signal. The underlying hardware problem must be corrected, either by replacing the faulty probe or repairing the wiring, before the error will clear permanently and normal oven operation can resume.

A knowledgeable DIYer can diagnose this error by using a multimeter to test the RTD probe's resistance at room temperature to determine if it is open or shorted. If the probe is faulty, replacing it is a relatively straightforward repair that involves disconnecting the old probe from the oven cavity and wiring harness and installing a compatible replacement. However, if the wiring harness or control board is involved, the repair becomes more complex and professional service may be advisable.

If only the RTD probe needs replacement, parts and labor typically range from around $150 to $350 depending on your location and service provider. If the wiring harness also needs repair or replacement, costs may increase moderately. A control board replacement, if required, can bring the total repair cost significantly higher, often in the $400 to $700 range or more.
