ICP Furnace Control Board for RGS244HEFA0AAAA — OEM Kit 1183618 | Ships Today

Overview

The 1183618 control board kit is the OEM integrated furnace control (IFC) for the ICP Tempstar Heil RGS244HEFA0AAAA gas furnace. This board is the brain of the furnace — it manages the ignition sequence, sequences the inducer and blower motors, monitors flame and limit safeties, and times each heating and cooling call. When it fails, the furnace typically loses heat entirely, locks out on a flashing diagnostic LED, or short-cycles the blower. The kit ships with the board and the mounting hardware needed for a direct OEM replacement, operating on the standard 24V control circuit.

Specifications

Compatibility

Designed as the factory replacement control board for the ICP Tempstar Heil RGS244HEFA0AAAA furnace and other models in the RGS family that originally shipped with the 1183618 board. Always match your existing board's part number and connector layout before installing.

1. Safety First — Disconnect power at the service switch and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the furnace blower-compartment door to expose the control board.
3. Document — Photograph every wire and connector location before disconnecting anything.
4. Remove — Unplug all molex connectors and spade terminals, remove the mounting screws, and lift out the old board.
