Overview
This is the genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RHH060H0CA0AAAA heat pump. The control board is the brain of the outdoor unit — it manages the defrost cycle, reversing valve operation, compressor timing, and safety lockouts. When this board fails the system may stop heating in defrost weather, run continuously, ice over, or refuse to start the compressor entirely. Replacing the board with the correct OEM kit restores proper sequencing and protects the compressor from short-cycling.

Compatibility
Engineered specifically for the ICP / Tempstar / Heil RHH060H0CA0AAAA heat pump and closely related RHH060 series outdoor units. Always confirm the printed part number on your existing board matches 1183618 before installing.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter at the board terminals.
- Access — Remove the outdoor unit control-panel access cover.
- Document — Photograph every wire and connector landing before disconnecting anything.
- Remove — Unplug the harness connectors, release the board standoffs/screws, and lift out the failed board.
- Install — Seat the new 1183618 board on the standoffs and reconnect each harness exactly per your photo, setting any defrost-time jumper to match the original.
- Test — Restore power and confirm proper startup, reversing-valve operation, and defrost initiation/termination.
Signs You Need a Replacement
- Heat pump ices over and never enters or exits defrost
