What the 2 flashes every 4 seconds error code actually means

Your Viking range is signaling that the electronic ignition control board has detected a problem with itself. This is the part that manages the spark and flame for your gas burners. Resetting the range by turning off the power may fix it if it was a temporary glitch, but if the flashing comes back, the board will need to be replaced.

Questions people ask about 2 flashes every 4 seconds

What does 2 flashes every 4 seconds mean on a Viking range?
This flash pattern indicates a control fault on the DSI (Direct Spark Ignition) module, which is the electronic board that manages gas burner ignition. The module has detected an internal fault condition it cannot resolve on its own. It does not indicate a problem with the igniter or gas valve specifically, but rather with the control board itself.
Is it safe to use my Viking range while it is showing the 2 flashes every 4 seconds error?
Operating the range with a faulted DSI module is not recommended. The DSI module controls critical ignition sequencing and flame monitoring functions, and a faulty module may not reliably manage these processes. To avoid the risk of ignition failure or unlit gas flow, stop using the affected burners until the fault is diagnosed and resolved.
How much does it cost to replace a DSI module on a Viking range?
The cost to replace a DSI module on a Viking range varies depending on the specific model and where the part is sourced. Parts alone typically range from around $100 to $300 or more for the module itself. If you hire a professional technician, labor costs will add to the total, bringing the overall repair cost to roughly $200 to $500 or higher depending on your location and service rates.
Will resetting my Viking range clear the 2 flashes every 4 seconds error?
Cycling power to the range is always the recommended first step, and it may clear the fault if it was caused by a transient condition such as a brief power interruption. If the 2-flash pattern returns after the power cycle, the DSI module has a confirmed internal fault and resetting alone will not resolve it. In that case, the module will need to be replaced.
How do I fix the 2 flashes every 4 seconds error on a Viking range?
Start by turning the range off at the breaker or unplugging it for several minutes, then restoring power. If the error clears, monitor the range to confirm normal operation. If the fault code returns, the DSI module will need to be replaced. Before replacing the module, inspect the wiring harness connections to the board to rule out a loose or corroded connector as the cause.
