ICP Furnace Control Board Kit for RGS102SFAA0AAA — Ignition Control | Ships Today

Overview

This OEM control board kit replaces ICP part number 1183618 for the ICP/Tempstar/Heil RGS102SFAA0AAA gas furnace. The integrated furnace control (IFC) board is the brain of the furnace: it sequences the inducer motor, hot surface igniter, gas valve, and blower, monitors the flame sensor and pressure/limit switches, and stores diagnostic fault codes on its LED. When the board fails, the furnace may be completely dead, ignite erratically, run the blower continuously, or flash a hard-lockout code even when every other component tests good.

Specifications

Compatibility

Installation Guide

3. Document — Photograph every wire harness and terminal on the old board before disconnecting.
4. Remove — Unplug all connectors, remove the mounting screws, and lift out the failed board.
