ICP Furnace Control Board Kit for RGS102HRAA0AAA — OEM Ignition Control | Ships Today

Overview

This is a genuine OEM furnace control board kit (part 1183618) for the ICP/Tempstar/Heil RGS102HRAA0AAA gas furnace. The integrated furnace control (IFC) is the brain of the system — it manages the ignition sequence, sequences the inducer and blower, monitors the flame sensor and pressure switch safeties, and runs diagnostics. When the board fails, the furnace may fail to start, short-cycle, blow cold air, or flash diagnostic fault codes. This kit replaces the complete board so the ignition and safety logic operate to factory spec.
