ICP Furnace Control Board Kit for RGS101LSCB0AAA — OEM Circuit Board | Ships Today

Overview

This genuine ICP furnace control board kit (part 1183618) is the integrated ignition control and brain of the ICP / Tempstar / Heil RGS101LSCB0AAA gas furnace. The board manages the entire heating sequence — inducer start, igniter warm-up, gas valve timing, flame sensing, blower timing, and safety lockouts — and continuously monitors limit and pressure switches. When a control board fails, the furnace may be completely dead, stall partway through the ignition sequence, short-cycle, or run the blower constantly. The kit includes the OEM board and mounting hardware so you can restore reliable, code-correct operation. Note board orientation and any onboard jumper or DIP settings before swapping.
