ICP Control Board Kit for RGS150SRCA0AAAA — OEM Part 1183618 | Ships Today

Overview

This is a genuine OEM control board kit (part number 1183618) for the ICP Tempstar Heil RGS150SRCA0AAAA gas furnace. The integrated furnace control board is the brain of the unit — it manages the ignition sequence, monitors safety switches, sequences the inducer and blower motors, and controls the gas valve through the heating and cooling cycles. When this board fails, the furnace may fail to ignite, short-cycle, throw flashing diagnostic LED fault codes, or stop responding to thermostat calls entirely. Replacing it with the correct OEM board restores reliable, manufacturer-specified operation.
