Viking Range Error Code No LED

No LED on a Viking range means the DSI (Direct Spark Ignition) module is receiving no power and shows no activity. The DSI board controls the electronic ignition system for the gas burners, so without power it cannot function. This condition points to a wiring or power supply issue upstream of the board rather than a fault within the board itself. The first step is to inspect the wiring and connectors leading to the DSI module.

With the DSI board receiving no power, the electronic ignition system is non-functional. The burners cannot be sparked automatically. You should not attempt to manually light burners with a match or lighter as a workaround while an electrical fault is present, and the range should not be used until the wiring issue is diagnosed and repaired.

No, resetting the range will not resolve this condition. The No LED state is caused by a physical lack of power reaching the DSI board, not a software or control fault that can be cleared by a reset. The underlying wiring issue must be found and corrected before the module will power on and the ignition system will operate normally.

Checking for a loose or disconnected wiring harness connector is something a careful DIYer can attempt after disconnecting power to the range. However, tracing wiring faults, testing for voltage with a multimeter, and replacing components like fuses, wiring harnesses, or the DSI board requires comfort with electrical diagnostics. If you are not experienced with appliance electrical systems, a qualified technician should perform the inspection.

Repair costs vary depending on the cause. If the issue is simply a loose connector, the cost is limited to a service call fee, typically in the range of $75 to $150. Wiring repairs or fuse replacements add parts costs on top of labor. If the DSI board itself needs replacement, parts and labor combined can range from $200 to $450 or more depending on the specific model and service rates in your area.
