ICP Furnace Control Board for RGS101LRCA0AAA — OEM Ignition Control Kit | Ships Today

Overview

This OEM control board kit (part 1183618) is the integrated furnace control (IFC) for the ICP / Tempstar / Heil RGS101LRCA0AAA gas furnace. The control board is the brain of the furnace — it manages the ignition sequence, monitors the flame sensor and pressure switches, sequences the inducer and blower motors, and protects the system through built-in safety lockouts. When a control board fails, the furnace may fail to ignite, short-cycle, run the blower continuously, or flash a diagnostic fault code on its onboard LED. Because this is a complete kit, it ships with the mounting hardware and harness adapters needed for a clean drop-in replacement.
