Viking Range Error Code 4 flashes every 4 sec

This flash pattern indicates a gas solenoid fault detected by the DSI (Direct Spark Ignition) board. The board controls the gas valve solenoid and has determined that the solenoid circuit is not operating correctly. The range enters a lockout state and displays this code to alert the user that service is required. The fault can originate from the wiring, the solenoid itself, or the DSI board.

No, you should not attempt to operate the range while this error is active. The fault indicates the gas solenoid control circuit is not functioning correctly, which means the gas valve may not operate as intended. Continuing to use the appliance under these conditions poses a potential safety risk, and the range should remain off until the fault is diagnosed and repaired.

Repair costs vary depending on the root cause. If the issue is a loose or damaged wire, the cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing the gas valve solenoid or the full gas valve assembly can add $100 to $400 or more in parts. A DSI board replacement can range from $150 to $350 in parts alone, with labor added on top depending on your location and technician rates.

A knowledgeable DIYer can begin by inspecting the wiring harness and connectors between the DSI board and the gas valve solenoid for visible damage, corrosion, or loose connections. However, any work involving the gas valve or internal board components should be approached carefully, and if you are not comfortable working with gas appliances, a qualified technician is recommended. Replacing a gas valve solenoid or DSI board typically requires disassembly of the range and familiarity with gas systems.

A power reset by turning off the circuit breaker for 30 to 60 seconds may temporarily clear the fault display, but the error will return if the underlying problem has not been corrected. The DSI board will continue to detect the solenoid fault each time the system attempts to operate. A reset alone is not a repair and does not address the root cause.
