Overview
This genuine OEM control board kit (part 1183618) is the electronic brain of the ICP / Heil / Tempstar RHH060K0XA0AAAA heat pump. It manages the defrost cycle, sequences the compressor and outdoor fan, switches the reversing valve through the 24V control circuit, and monitors sensor inputs to protect the system. Supplied as a complete kit with the mounting hardware and connectors needed for a clean swap. Control boards fail from voltage surges, lightning, corrosion on the relays, and simple age — and the symptoms are wide-ranging: no defrost in cold weather (outdoor coil ices over), no changeover between heating and cooling, intermittent operation, blown low-voltage fuses, or a unit that is completely dead despite good incoming power. Because the board ties every major component together, a failing board often masquerades as a bad contactor, sensor, or reversing valve, so confirming the board is a smart move before replacing other parts.
