Viking Range Error Code 5 flashes every 4 seconds

This flash pattern indicates a control fault on the DSI (Direct Spark Ignition) module, which is the board that controls gas ignition, spark generation, and flame sensing on your range. The module has detected an internal problem it cannot resolve on its own. A power cycle is the first recommended step, and if the code returns, the DSI module requires replacement.

It is not advisable to continue using the range while this fault is active. The DSI module controls gas valve operation and ignition, so a fault in this module means burner control may be unreliable. Discontinue use until the fault is diagnosed and resolved to avoid any risk associated with improper gas valve or ignition behavior.

The total cost for a DSI module replacement on a Viking range typically ranges from $150 to $400 or more, depending on the specific model and labor rates in your area. The part itself generally accounts for a significant portion of that cost. Getting a quote from an authorized service technician familiar with Viking appliances is recommended before proceeding.

A power cycle reset will sometimes clear this fault if it was caused by a temporary voltage irregularity or corrupted control state. To reset, switch off the range at the circuit breaker for at least 60 seconds, then restore power. If the 5-flash code returns after the reset, the DSI module has an internal fault that cannot be cleared by resetting and the module must be replaced.

Start by cycling power to the range at the circuit breaker for 60 seconds, then restore power and test operation. If the fault code does not return, the issue was a temporary control error. If the 5-flash pattern comes back, inspect the wiring harness connections at the DSI module for looseness, corrosion, or damage. If connections are good and the fault persists, the DSI module itself needs to be replaced.
