Viking Range Error Code DSI No LED

DSI No LED means the Direct Spark Ignition module on your Viking range is not receiving power, confirmed by the absence of any LED illumination on the DSI board. Without power to this module, the electronic ignition system cannot function and burners will not spark. The condition points to a supply-side problem such as a wiring fault or blown fuse rather than a failure within the ignition circuit itself.

You should not attempt to use the range in this condition. With the DSI module unpowered, the automatic ignition system is completely non-functional, meaning burners cannot ignite through normal operation. Attempting to manually light burners while the ignition system is in an unknown fault state is not advisable until the root cause has been diagnosed and repaired.

Repair cost depends on the root cause. If the fix is a loose connector or a failed fuse, parts cost is minimal, typically in the range of a few dollars to around $20, though a service call fee will apply if a technician is involved. If the DSI module board itself requires replacement, parts alone can range from roughly $80 to $250 or more depending on the specific model, plus labor. Accurate cost estimates require diagnosis to confirm which component has failed.

A knowledgeable DIYer can begin by inspecting the wiring harness and connectors leading to the DSI module for loose connections, corrosion, or visible damage, and by checking any fuses in the ignition circuit. If wiring and fuses check out and voltage is confirmed at the module input, the DSI board itself likely needs replacement, which is a more involved repair. Working near gas components and live electrical circuits carries risk, so if you are not comfortable with both gas appliance safety and electrical diagnostics, professional service is recommended.

A simple power reset is unlikely to resolve this condition because DSI No LED indicates a hardware issue, specifically absent power to the module, rather than a software or logic fault. Unless a loose connector reseats itself during the process, resetting power will not restore the LED or module function. The underlying wiring, fuse, or component fault must be physically identified and corrected.
