Viking Range Error Code 4 flashes (DSI)

The 4 flashes code on a Viking range indicates a gas solenoid fault in the Direct Spark Ignition system. The solenoid valve controls gas flow to the oven burner, and the control board has detected that it is not operating properly. This prevents the oven from completing its ignition sequence. The fault points to the solenoid itself, its wiring, or the connectors in the circuit.

The oven should not be used while this fault is active. The 4 flashes code indicates a problem in the gas solenoid circuit, which means the control system cannot reliably manage gas flow to the burner. Attempting to operate the oven under these conditions is not recommended. Surface burners may still function, but confirm normal operation before use.

Cycling power to the range may temporarily clear the fault display, but the error will return if the underlying problem with the gas solenoid or its wiring has not been resolved. A reset is not a fix and should only be used as a step in diagnosing whether the fault is intermittent or persistent. The solenoid circuit must be properly inspected and repaired before the range will operate reliably.

A knowledgeable DIYer can inspect wiring and connectors for obvious damage or looseness, which are common causes of this fault. However, any work involving the gas solenoid valve or the wiring connected to it should be done with the power disconnected and the gas supply shut off. If the solenoid valve itself needs replacement, many homeowners prefer to have a qualified technician handle the repair due to the gas supply components involved.

Repair costs depend on which component has failed. Wiring repairs or connector replacements are generally less expensive, often falling in the range of $100 to $250 including labor. A replacement gas solenoid valve typically adds parts costs that can push the total to $200 to $450 or more. An ignition control board replacement is generally the most expensive scenario, often ranging from $300 to $600 depending on the specific model and labor rates in your area.
