Overview
This is the genuine OEM control board kit (part 1183618) for the ICP / Tempstar / Heil RGS213HRAA0AAAA gas furnace. The integrated furnace control board is the brain of the system: it sequences the inducer, igniter, gas valve, and blower, monitors safety inputs (limit switches, flame sensor, pressure switch), and flashes diagnostic fault codes through its onboard LED. The kit ships with the mounting hardware and instructions needed for a clean swap.
Boards fail from heat stress, voltage surges, corroded relays, and burned flame-sense or igniter traces. Symptoms include a completely dead furnace, no response to a thermostat call, the blower or inducer running continuously, repeated lockouts, or an LED throwing a hard fault code. Because the board ties every component together, replacing a failed one restores correct sequencing and safety supervision across the whole furnace.
