Overview
This OEM control board kit (part number 1183618) is the integrated furnace control for the ICP / Tempstar / Heil RGS102LECA0AAA gas furnace. The board is the brain of the furnace: it manages the ignition sequence, sequences the inducer and blower motors, monitors the flame and limit switches, and runs the safety lockouts that protect the system. Control boards fail from power surges, heat, corrosion, and failed onboard relays. Symptoms include no response to a heat call, the inducer or blower not running, error codes flashing on the diagnostic LED, or a furnace stuck in lockout. This kit ships with the correct factory board so the furnace's timing and safety logic are restored exactly to spec.
