Overview
This OEM control board kit (part #1183618) is the electronic brain of your ICP RHH102H0BA0AAAA heat pump. It manages the defrost cycle, compressor timing/anti-short-cycle protection, reversing valve switching, and condenser fan operation based on inputs from the thermostat, defrost thermostat, and pressure switches. Supplied as a complete kit, it includes the replacement board and required hardware/connectors so you can swap a failed unit without sourcing extra parts. A failed control board can cause a wide range of symptoms — the system may not run at all, may not switch between heating and cooling, may ice up because defrost never initiates, or may short-cycle. Because the board is exposed to outdoor temperature swings and moisture, corroded relays and cracked solder joints are common failure points.
