Overview
This is the OEM integrated furnace control board for the ICP (Tempstar / Heil) RGS214HDHLBRETA gas furnace. The control board is the brain of the unit — it manages the ignition sequence, blower timing, safety lockouts, and the reheat circuit, while coordinating signals between the thermostat, igniter, gas valve, and indoor blower motor. This listing covers the OEM control board kit (part 1183618), the reheat circuit board (1186501), and the IFCB-to-IFM wiring harness (1186494) that ties the board to the indoor fan motor. When the board fails, the furnace typically will not start, short-cycles, or throws blinking fault codes at the diagnostic LED. Specs: 24V control logic, on-board diagnostics, integrated reheat circuit.
