ICP Furnace Control Board Kit for RGS210STCA0AAAA | Ships Today

Overview

This genuine OEM control board kit, part number 1183618, is the furnace's main integrated control for the ICP, Tempstar, and Heil RGS210 gas furnace. The board is the brain of the system: it sequences ignition, manages the inducer and blower motors, monitors the limit and pressure safety switches, controls the gas valve, and reads flame sense feedback. The kit includes the board and the hardware needed to replace a failed unit. When the control board fails, symptoms range from no response on a heat call to erratic blower behavior, repeated lockouts, or diagnostic LED fault codes that point back to the board itself.
