ICP Control Board for RHH060L0CA0AAAA – 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 RHH060L0CA0AAAA. The control board governs the entire outdoor unit — managing the defrost cycle, reversing-valve sequencing, compressor staging, and safety lockouts. It interprets thermostat demand along with coil, ambient, and pressure inputs, then energizes the contactor, reversing valve, and fan to provide heating or cooling. A failed board typically leaves the unit unresponsive to the thermostat, allows the coil to ice over because defrost never starts, or causes erratic short-cycling.

Installation Guide

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 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.
