Viking Range Error Code Cycle 3 flashes / Clean ON

This error indicates an A/D Stuck fault in the self-cleaning oven control board on Viking 30", 36", and 48" RH series ovens. The A/D converter inside the control board has stopped cycling through its conversion process, meaning the board can no longer accurately read temperature sensor data. The oven will not operate safely until this fault is resolved.

A power reset by switching off the circuit breaker for 60 seconds may temporarily clear the fault display, but if the underlying cause is a failed control board or a shorted temperature sensor, the error will return once the oven resumes operation. A reset alone does not repair the defective component causing the A/D stuck condition.

Repair costs vary depending on whether the issue is a failed control board, a faulty temperature sensor, or a wiring problem. A replacement oven temperature sensor typically runs in the range of $30 to $80 for the part, while a self-cleaning oven control board for Viking RH series models can range from $150 to $400 or more. Adding professional labor, total repair costs commonly fall between $200 and $600 depending on the diagnosis.

Some preliminary checks are within reach of a knowledgeable DIYer, including inspecting the oven temperature sensor for visible damage and checking wiring harness connectors for corrosion or loose pins. However, if the control board itself has failed, replacing it requires working with high-voltage components and correctly configuring the new board, which is best handled by a qualified appliance technician.

It is not recommended to operate the oven, particularly the self-clean cycle, while this error is present. The A/D stuck fault means the control board cannot accurately monitor oven temperature, which removes a critical safety check during high-heat operation. Discontinue use and have the oven inspected before running any cooking or cleaning cycles.
