This PCB is designed to support SSR relays for controlling incoming Power(L) to the Igniter and Auger. This board also has circuitry to support a 12V PWM fan. This board uses compact solid state relays that are able to handle high power. This is an alternative to using an off the shelf relay module which simplifies the wiring and even allows you to use the OEM harness.
