This genuine OEM control board kit (part number 1183618) is the electronic brain of the ICP/Tempstar/Heil RHH060S0BA0AAAA heat pump. The board manages the 24-volt control logic for the outdoor unit — sequencing the compressor contactor, reversing valve, and condenser fan, and on heat pump models running the defrost timing that periodically clears frost from the outdoor coil. Supplied as a complete kit with mounting hardware and connectors, it ensures correct, reliable operation across heating and cooling cycles. A failed board shows up as no compressor operation, a unit stuck in defrost or never defrosting, intermittent or erratic cycling, or visible burn marks and failed relays on the board itself.
