ICP Control Board Kit for RGS213HFCA0AAAA — OEM 1183618 | Ships Today

Overview

This is a genuine ICP / Heil / Tempstar control board kit (OEM part number 1183618) for the RGS213HFCA0AAAA gas furnace. The furnace control board (often called the integrated furnace control, or IFC) is the brain of the system: it sequences the inducer, igniter, gas valve, and blower, monitors limit and pressure switches, manages flame sense, and runs diagnostics and safety lockouts. When the board fails you may see no response on a heat call, a stuck blower, blank or error-flashing diagnostic LEDs, or random lockouts. The kit ships as a complete replacement assembly to restore full furnace operation.
