ICP Furnace Control Board for RGS101HECB0AAA — OEM Kit 1183618 | Ships Today

Overview

This OEM control board kit (part 1183618) is the integrated furnace control (IFC) for the ICP / Tempstar / Heil RGS101HECB0AAA gas furnace. The board is the brain of the furnace — it manages the ignition sequence, monitors the pressure switch and limit safeties, energizes the igniter and gas valve, controls inducer and blower timing, and proves flame through the sensor. When this board fails, the furnace may not respond to the thermostat, may lock out, or may run the blower continuously. Boards typically fail from voltage surges, corrosion, cracked solder joints, or burned relays. This kit includes the factory-programmed board and required hardware so the replacement drops in with the correct firmware and diagnostic LED behavior for this model.
