ICP Furnace Control Board Kit for RGS210SDAA0AAAA — OEM Replacement | Ships Today

Overview

This is a genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS210SDAA0AAAA gas furnace. The integrated furnace control board is the brain of the system: it sequences ignition, manages the inducer and blower motors, monitors safety circuits such as limits and pressure switches, controls flame sensing, and diagnoses faults via blinking error codes. When the board fails, the furnace may not respond to the thermostat, the blower or inducer may not run, or the system may short-cycle and throw repeated fault codes. This kit includes the replacement board so you can restore full, code-compliant furnace operation.
