Overview
This OEM control board kit (part 1183618, KIT CONTROL BOARD) is the electronic brain of the ICP/Heil/Tempstar RHH102H0CA0AAAA heat pump. It manages defrost timing, reversing valve operation, fan and compressor sequencing, and safety interlocks. The kit ships as a complete plug-in assembly with the mounting hardware and connectors needed for a direct swap. Boards fail from voltage surges, corroded traces, failed relays, or burnt connectors — leaving the unit with no outdoor operation, stuck defrost, or erratic mode changes. Replacing the board restores correct sequencing and protects the compressor.
