Viking Oven Error Code RTD ERROR

The RTD ERROR code means the oven's control board has detected that the resistance temperature detector sensor circuit is either open (broken) or shorted (making unintended contact). The RTD sensor is responsible for measuring the oven cavity temperature, and this fault prevents the board from getting a valid temperature reading. As a result, the oven disables normal heating operation until the fault is corrected by a qualified technician.

You should not attempt to use the oven while this error is active. The oven cannot accurately measure its internal temperature with a faulty RTD sensor, which means heating could be uncontrolled or unpredictable. Discontinue use and arrange for service before operating the appliance again.

Repair costs vary depending on whether the issue is the RTD sensor itself, the wiring harness, or the control board. RTD sensor replacements are generally the least expensive component repair, while control board replacement can be significantly more costly. Including parts and labor, total repair costs can range from around $150 to $600 or more depending on the specific fault and your location.

Viking recommends contacting an authorized dealer or service agency for this error. Diagnosing the fault properly requires a multimeter to measure sensor resistance and the knowledge to inspect low-voltage wiring circuits safely. Attempting repairs without the right tools or technical background risks further damage to the control board or wiring harness.

Resetting the oven by cutting power at the breaker and restoring it may temporarily clear the error display, but the code will return if the underlying sensor or wiring fault has not been repaired. A reset does not fix the hardware problem and should not be relied on as a solution.
