ICP Control Board Kit for RGS210HDAA0AAAA — OEM 1183618 Integrated Furnace Control | Ships Today

Overview

This is a genuine OEM integrated furnace control board kit (part number 1183618) for the ICP Tempstar Heil RGS210HDAA0AAAA gas furnace. The control board is the brain of the furnace — it sequences the ignition cycle, monitors safety limits and flame, controls the inducer and blower motors, and manages the 24V control circuit. A failed board is one of the most common causes of a furnace that will not start, short cycles, or locks out on ignition. Symptoms of a failing control board include no response when the thermostat calls for heat, blower running constantly, error codes on the diagnostic LED, intermittent operation, and burnt or scorched spots on the board itself.
