ICP Furnace Control Board for RGS101HRCB0AAA — OEM 1183618 | Ships Today

Overview

This OEM integrated furnace control board kit (1183618) is the brain of the ICP / Heil / Tempstar RGS101HRCB0AAA gas furnace. It manages the ignition sequence, monitors safety limits and flame sense, controls the inducer and blower motors, and coordinates the timing between the thermostat call and burner operation. When this board fails, the furnace may lock out, fail to ignite, or stop responding to the thermostat entirely. The kit ships as a complete control assembly for a direct factory replacement.
