This OEM control board kit (part number 1183618, factory reference KIT CONTROL BOARD) is the electronic brain of the ICP RHX060K0XA0AAA heat pump. It manages defrost timing and termination, sequences the compressor and reversing valve, monitors the 24V demand signals from the thermostat, and protects the system with built-in time delays. The kit ships with the board and the mounting/wiring hardware needed for a clean replacement. A failing control board produces some of the most frustrating intermittent faults in HVAC service: no response to a heating or cooling call, the unit stuck in or never entering defrost, ice buildup on the outdoor coil in heat-pump mode, or relays that chatter and fail to sequence. Replacing the board with the OEM-matched kit restores correct sequencing and defrost logic.
