Viking Range Error Code 5 flashes every 4 seconds

The 5 flashes every 4 seconds fault code on a Viking range indicates a control fault originating within the DSI (Direct Spark Ignition) module. The DSI module is the electronic control board responsible for managing the ignition sequence on gas burners, including generating the spark, monitoring flame presence through the flame sensor circuit, and regulating the gas valve timing. When the module detects an internal fault it cannot resolve through normal operation, it signals this condition by flashing the indicator light 5 times in a repeating 4-second cycle.

This type of control fault typically points to a failure within the DSI module's internal logic or sensing circuitry rather than an external wiring or component issue. Common triggers include a corrupted control state caused by a power surge or voltage irregularity, a hardware failure within the module itself, or a persistent input signal that puts the module into a fault condition it cannot exit. Because the DSI module integrates spark generation, flame detection, and gas valve control into a single assembly, an internal fault can prevent all ignition-related functions from operating.

The first recommended step is a power cycle, which clears any temporary fault states stored in the module's logic. To do this, shut off the range at the circuit breaker for at least 60 seconds, then restore power and attempt normal operation. If the 5-flash code returns after the power cycle, the DSI module has an unrecoverable internal fault and requires replacement. Continuing to operate the range with a faulted DSI module is not advisable, as gas valve control may be compromised.
