ICP Control Board Kit for RGS214SFAA0AAAA — OEM 1183618 | Ships Today

Overview

This genuine OEM control board kit (part number 1183618) is the electronic brain of the ICP/Tempstar/Heil RGS214SFAA0AAAA system. The board manages ignition sequencing, blower and inducer timing, safety lockouts, and communication with the thermostat. A failed board produces erratic symptoms — no response to thermostat calls, blower or inducer that won't start, repeated diagnostic flash codes, or a completely dead unit. Supplied as a complete kit for a clean, direct OEM replacement that restores correct operation and protects the rest of the system.
