ICM Controls ICM2818 Furnace Control Board

The ICM Controls ICM2818 Furnace Control Board is used to manage ignition sequencing and operational control within gas heating equipment. It coordinates signals from the thermostat and safety sensors to regulate the inducer motor, gas valve, ignition, and blower control. The component processes electrical inputs and directs system actions to support furnace startup and shutdown cycles. It is installed in residential and commercial furnace assemblies where control logic is required for heating operation. Mounted inside the furnace control compartment, it supports interaction between electrical circuits and mechanical components during heating demand.
