ICP Control Board Kit for RHH102S0CA0AAAA — OEM Defrost Board | Ships Today

Overview

This is the genuine OEM ICP control board kit, part number 1183618 (KIT CONTROL BOARD), for the RHH102S0CA0AAAA heat pump. The control board is the brain of the outdoor unit — it manages the defrost cycle, reversing valve timing, compressor and fan sequencing, and safety lockouts. When the board fails, you'll see erratic operation: no defrost (iced-up coil), no heat or cool, the fan or compressor not staging correctly, or a completely dead unit. The kit ships with the board and mounting hardware for a complete OEM replacement.
