Overview
This genuine OEM control board kit (part number 1183618, "KIT CONTROL BOARD") is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS180LSAA0AAAA gas furnace. The board is the brain of the furnace: it manages the ignition sequence, monitors the flame/pressure switch and limit safeties, controls the inducer and blower motors, and steps the system through each heat and cool cycle while flashing diagnostic codes via its onboard LED. Because it switches the low-voltage 24V control circuit and sequences every component, a failed board can produce a wide range of faults. Common symptoms include no response on a thermostat call, blower or inducer that won't start (or won't shut off), erratic short-cycling, repeated lockouts, or visibly burnt traces, scorched relays, and blown fuses on the board.
