ICP Control Board Kit for RHH102S0BA0AAAA — OEM Defrost Board | Ships Today

Overview

This OEM control board kit (part 1183618) is the electronic brain of the ICP RHH102S0BA0AAAA heat pump. It manages defrost cycle timing, reversing valve sequencing, compressor and fan staging, and the 24V control logic that ties the thermostat, contactor, and sensors together. When a control board fails, symptoms range from no operation at all to erratic behavior — ice buildup on the outdoor coil from missed defrost cycles, the unit short-cycling, or stages failing to energize. Supplied as a complete OEM kit for a clean, direct replacement.
