Viking Range Error Code 3 flashes every 4 sec

This flash pattern indicates an ignition lockout fault. The control board attempted to ignite a burner and did not detect a flame after completing its full retry sequence. The system then locks out as a safety measure to prevent unburned gas accumulation. The root cause typically lies with gas flow, the spark electrode, spark leads, or the gas solenoid valve.

The affected burner should not be used while the lockout is active, as the control has determined it cannot reliably establish a flame. Using a burner in a fault state risks unburned gas release if the solenoid opens without successful ignition. Discontinue use of the affected burner and have the system inspected before resuming operation.

Repair costs vary depending on which component has failed. Electrode replacement is typically on the lower end of the cost range, while a gas solenoid valve or control board replacement will be more expensive. In general, expect parts and labor costs to range from around $150 to $500 or more depending on the failed component and your location. Obtaining a diagnostic assessment from a qualified technician before ordering parts is recommended.

You can attempt a reset by turning the range off and cutting power at the breaker for several minutes before restoring it. However, if the underlying cause has not been corrected, the control board will repeat its ignition attempts and return to lockout, triggering the fault again. A reset is only a temporary measure and should be followed by a full diagnostic of the ignition system components.

Start by confirming that gas is flowing normally to the range and that the supply valve is fully open. Then inspect the spark electrode for cracks, heavy deposits, or misalignment with the burner port, and check that all spark leads are intact and securely connected. If those components check out, the gas solenoid valve should be tested for proper operation. A qualified technician can perform voltage and continuity tests on these components to isolate the faulty part.
