ICP Furnace Control Board Kit for RGS101LECA0AAA | Ships Today

Overview

This is a genuine OEM integrated furnace control board kit (part 1183618) for the ICP/Tempstar/Heil RGS101LECA0AAA. The control board is the brain of the furnace — it sequences the ignition cycle, manages the inducer and blower motors, monitors safety devices like the pressure switch and limit, energizes the hot surface igniter and gas valve, and reads flame feedback. When a board fails, the furnace may short-cycle, fail to ignite, leave the blower running continuously, or go completely dead. This kit includes the board and the hardware needed for a complete replacement.
