Viking Range Error Code 2 flashes every 4 sec

This flash pattern signals a DSI (Direct Spark Ignition) control fault on your Viking range. The DSI control board is the module that manages the gas burner ignition sequence, and it has detected an internal fault or failure. The range uses the repeating 2-flash pattern to alert you that the ignition control system requires attention. If cycling power does not clear the fault, the DSI board will need to be replaced.

The DSI control board governs the ignition sequence and gas valve operation for the affected burner circuit. A faulted DSI board means the ignition system is not functioning as designed, which creates an unreliable and potentially unsafe operating condition. It is best to avoid using the affected burner circuit until the fault is diagnosed and the DSI board is replaced if necessary.

Repair costs depend on whether the DSI board itself needs replacement or if the fix is limited to correcting a wiring connection issue. DSI control board parts for Viking ranges typically range from around $100 to $300 or more depending on the specific model. Adding professional labor for diagnosis and installation, total repair costs commonly fall in the range of $200 to $500. Getting a firm quote from a qualified technician after diagnosis will give you the most accurate estimate for your specific unit.

A power cycle is the first recommended step and will resolve the fault if it was caused by a temporary logic error or power fluctuation. Turn the range off at the breaker or unplug it, wait at least 30 seconds, and restore power before testing the burners again. If the 2-flash code returns after the reset, the DSI control board has a confirmed fault and will need to be replaced rather than simply reset.

Start by cycling power to the range completely at the breaker for at least 30 seconds, then restore power and test the burners. If the 2-flash fault code returns, the DSI control board requires replacement. Before replacing the board, inspect the wiring harness connectors at the DSI module for looseness, corrosion, or heat damage, as a poor connection can also trigger this fault.
