Viking Range Error Code 8 flashes every 4 sec

This flash pattern indicates a gas solenoid fault detected by the DSI (Direct Spark Ignition) board. The board controls the solenoid that opens the gas valve during ignition, and it has detected an abnormal condition in that circuit. The range will not operate until the fault is corrected. The first step is to inspect the wiring and the gas solenoid component itself.

No, you should not attempt to use the range while this fault is present. The error indicates the ignition system cannot reliably control the gas solenoid valve, which means gas flow to the burner may not be properly managed during an ignition attempt. Continued use under this condition poses a potential safety risk, and the range should remain off until the fault is diagnosed and repaired.

Cycling power to the range may temporarily clear the flash sequence, but the fault will return if the underlying problem with the gas solenoid circuit has not been fixed. A reset does not repair a failed solenoid, a damaged wire, or a faulty DSI board. The fault code will continue to appear until the root cause is properly diagnosed and corrected.

A knowledgeable DIYer can start by checking the wiring harness and connectors between the DSI board and the gas solenoid for obvious damage or loose connections. However, testing solenoid coil resistance and diagnosing the DSI board requires a multimeter and some technical comfort. Any work near gas components should be done with the gas supply shut off, and if you are not confident in those steps, a qualified appliance technician should perform the repair.

Repair cost depends on what component has failed. If the issue is a loose connector or damaged wire, labor costs alone may apply, typically in the range of $100 to $200 for a service call. A replacement gas solenoid or gas valve assembly can add $150 to $400 in parts. A DSI board replacement is generally in the $200 to $500 range for parts, plus labor. Getting a diagnostic visit will help determine the exact component involved before committing to a repair.
