The ICM ICM2818 furnace control board is a reliable OEM-replacement integrated control for Nortek/Intertherm/Nordyne/Miller/Revolv furnaces, replacing OEM part 903429. It manages the ignition sequence, gas valve, inducer, and circulating blower while monitoring system safeties.
The board operates on a 120 VAC, 60 Hz input with an 18–30 VAC control circuit, and drives a 1/5 HP blower, a 1/100 HP inducer, a 6.0 A hot surface igniter, and a 0.5 A gas valve.
