ICP Furnace Control Board for RGS210LDAA0AAAA — OEM Ignition Control Kit | Ships Today

Overview

This OEM control board kit (part #1183618) is the brain of your ICP Tempstar/Heil RGS210LDAA0AAAA gas furnace. The integrated furnace control (IFC) manages the entire heating sequence — ignition timing, blower and inducer operation, safety lockouts, and flame verification. When it fails, the furnace may fail to ignite, short-cycle, run the blower continuously, or throw diagnostic fault codes via the onboard LED. Because it coordinates every component, a faulty board is one of the most common causes of a no-heat call. This is the genuine OEM replacement kit, ensuring exact pin-out, relay, and firmware compatibility with your unit.
