ICP Furnace Control Board Kit for RGS102HRBB0AAA — OEM 1183618 | Ships Today

Overview

This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS102HRBB0AAA furnace. The board is the brain of the furnace: it sequences the ignition cycle, energizes the inducer and blower, monitors the flame sensor and limit switches, and manages safety lockouts. Cracked solder joints, blown relays, burnt traces, and failed flame-sense circuitry all cause hard-to-diagnose intermittent faults. The kit includes the board and mounting hardware needed for a complete replacement, restoring reliable ignition sequencing and safety control.
