ICP Control Board for RHH060L0XA0AAAA – OEM Kit 1183618 Defrost Control | Ships Today

Overview

This is the genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil heat pump model RHH060L0XA0AAAA. The control board is the brain of the outdoor unit, managing the defrost cycle, reversing-valve sequencing, compressor staging, and safety lockouts. It reads inputs from the thermostat, ambient and coil temperature sensors, and pressure switches, then energizes the contactor, reversing valve solenoid, and fan to deliver heating or cooling on demand. When this board fails the system commonly stops responding to thermostat calls, ices over because defrost never initiates, or short-cycles the compressor.

Compatibility

2. Access – Remove the outdoor unit control-box service panel.
3. Document – Photograph every wire and connector position before disconnecting.
4. Remove – Unplug the low-voltage harness, release the standoffs or mounting screws, and lift out the old board.
5. Install – Seat the new board on the standoffs and reconnect each harness exactly per your photos.
6. Test – Restore power, run a heating and cooling call, and confirm a proper defrost cycle.
