ICP Furnace Control Board for RGS244HTAA0AAAA — OEM Kit 1183618 | Ships Today

Overview

This is the genuine OEM Integrated Furnace Control (IFC) board kit, part number 1183618, for the ICP/Heil/Tempstar RGS244HTAA0AAAA gas furnace. The control board is the brain of the furnace: it manages the ignition sequence, monitors the flame sensor and pressure switch, sequences the inducer and blower motors, and runs continuous safety diagnostics. When this board fails the furnace will not respond reliably — common symptoms include no ignition, the unit short-cycling, the blower running constantly, or no 24V output to the gas valve. This kit ships with the board and required hardware so you can restore safe, code-compliant operation.
