This board controls inducer and blower fan motors, the hot surface ignitor, and the gas valve. It also monitors timing, trial for ignition flame sensing, the pressure and limit switches, and lockout. Additionally, it is designed for 100 percent gas shutoff in case of ignition failure and is compatible with a 24 VAC standard thermostat.
