ICP Furnace Control Board Kit for RGS102HRCB0AAA — OEM 1183618 | Ships Today

Overview

This is the genuine OEM integrated furnace control board kit (part 1183618) for the ICP / Heil / Tempstar RGS102HRCB0AAA gas furnace. The control board is the brain of the furnace — it sequences the ignition cycle, energizes the inducer and hot surface igniter, opens the gas valve, monitors flame and pressure switch safeties, and times the blower on and off. When the board fails the furnace may be completely dead, stuck in a fault, or short-cycle unpredictably. Common failure signs include no response from the thermostat, a blinking diagnostic LED indicating an internal fault, blower that runs continuously, or burned and corroded relays and connectors on the board itself.
