VIKING VIKING OVEN/RANGE Not Heating Convection Fan Works

Oven Igniter

In gas-fired models, the igniter must draw a specific amperage to heat the bi-metal strip inside the gas safety valve. Over time, the igniter's resistance increases due to thermal degradation, preventing it from pulling the current required to open the valve. This results in a functional control system and fan, but a total lack of ignition and heat.

Bake Heating Element

In electric models, the bake element is a resistive load that converts electrical energy into heat. Repeated thermal expansion and contraction cycles eventually cause the internal filament to fracture (open circuit), often at a point of high-resistance 'blistering.' This allows the convection fan to operate while the main heat source remains inert.

Relay Control Board

The relay board acts as the high-current switch for the heating elements or igniter circuits. Mechanical fatigue or carbon buildup on the relay contacts can prevent the circuit from closing, even when the control logic and fan motor circuits are successfully energized. This 'dry' contact failure prevents power from reaching the heating components.
