ICP Furnace Control Board Kit for RGS102HSAB0AAA — OEM Replacement | Ships Today

Overview

This OEM control board kit (part 1183618) for the ICP / Heil / Tempstar RGS102HSAB0AAA gas furnace is the integrated furnace control that manages the entire heating sequence — igniter timing, gas valve operation, inducer and blower relays, flame sensing, and safety lockouts. It monitors the limit and pressure switches and shuts the system down if a fault is detected. A failed board causes no-heat calls, erratic blower behavior, blinking diagnostic LEDs, or a furnace that won't respond to the thermostat. The kit ships with the board and mounting hardware for a direct OEM replacement.

Specifications

Compatibility

Fits the ICP RGS102HSAB0AAA furnace and related RGS-series gas furnaces under the Heil, Tempstar, and Comfortmaker brands. Match the OEM part number on your existing board before ordering, as control boards are model-specific.

3. Document — Photograph every connector and wire location on the old board before disconnecting.
