Overview
This genuine OEM control board kit (1183618) is the brain of your ICP RHH060S0CA0AAAA heat pump. It manages the defrost cycle timing, reversing-valve and contactor outputs, and the safety sequencing that protects the compressor. Supplied as a complete kit with mounting hardware and connectors for a clean replacement. When the board fails, the heat pump may stop defrosting (allowing ice to build on the outdoor coil), lock out, fail to switch between heat and cool, or stop responding to thermostat calls entirely.
