ICP Control Board Kit for RGS210HEEA0AAAA — OEM 1183618 | Ships Today

Overview

This genuine OEM control board kit, part number 1183618, is the integrated furnace control (IFC) that manages the entire heat cycle for ICP, Heil, and Tempstar gas furnaces. The board sequences the inducer, igniter, gas valve, and blower; monitors safety inputs such as the flame sensor, pressure switch, and limit; and flashes diagnostic fault codes when something is wrong. Supplied as a complete kit for straightforward replacement, it restores reliable ignition timing, blower control, and safety monitoring. A failed board is a common cause of a furnace that is completely dead, won't advance through its ignition sequence, or throws erratic fault codes.

Specifications

Compatibility

Built for the ICP/Tempstar/Heil RGS210HEEA0AAAA gas furnace and other ICP-family models that use control board kit 1183618. Verify the part number on your existing board before ordering, as control boards are model- and revision-specific.

Installation Guide

2. Access — Remove the control compartment service panel.
3. Document — Photograph every wire harness and connector position on the old board before disconnecting.
4. Remove — Unplug each connector, release the board from its standoffs, and lift it out.
5. Install — Mount the new board, then reconnect each harness to its matching terminal per your photo and the wiring diagram.
6. Test — Restore power, run a full heat cycle, and confirm correct ignition sequencing with no fault codes.

Signs You Need a Replacement
