Overview
This OEM control board kit (part 1183618) is the brain of the ICP / Tempstar / Heil RGS101HTCA0AAA gas furnace. The integrated furnace control manages the entire heating sequence — it reads the thermostat call, runs the inducer and pressure-switch proving cycle, energizes the hot surface igniter, opens the gas valve, monitors the flame sensor, and times the blower on and off delays. It also runs continuous self-diagnostics and flashes fault codes through its onboard LED. When this board fails, the furnace may be completely dead, stick in a single stage of the sequence, short-cycle, or run the blower constantly. The board is vulnerable to power surges, overheating, cracked solder joints, and failed relays. This kit is a direct-fit replacement that restores full, code-correct furnace operation.
