Viking Range Error Code 5 flashes

Five flashes on a Viking range indicate a DSI control fault. DSI stands for Direct Spark Ignition, and this code means the ignition control module has detected a problem during the ignition sequence or internally within the board itself. It can result from a temporary lockout condition or a component failure. Cycling power is the first recommended step to determine whether the fault clears on its own.

You should not attempt to operate the affected burner while the 5-flash fault is active, as the ignition system is not functioning correctly. Using a burner with a malfunctioning ignition control could result in unburned gas accumulating near the appliance. Keep the gas supply to the range turned off until the fault is diagnosed and resolved.

Repair costs depend on what component has failed. If only a power cycle or wiring fix is needed, costs may be minimal or limited to a service call fee, typically in the range of $75 to $150. If the DSI control board requires replacement, parts and labor combined can range from $200 to $500 or more depending on the specific model and local labor rates.

A power cycle will sometimes clear the 5-flash code if the DSI module entered a lockout state after a failed ignition attempt. To reset, turn off the range at the breaker or unplug it, wait at least 30 seconds, then restore power. If the 5-flash code returns after the reset, the fault is persistent and further diagnosis or DSI board replacement is needed.

A power cycle is a straightforward first step that any homeowner can safely perform. If the fault persists, checking wiring connections and the gas supply valve is within reach for a knowledgeable DIYer. However, replacing the DSI control board involves working with gas appliance electronics and is generally best handled by a qualified appliance technician to ensure the repair is done safely and correctly.
