ICP Control Board Kit for RHH060L0BA0AAAA – OEM 1183618 | Ships Today

Overview

This OEM control board kit (ICP part number 1183618 KIT CONTROL BOARD) is the electronic brain of the ICP/Tempstar/Heil RHH060L0BA0AAAA heat pump. It manages defrost timing and termination, sequences the compressor and fan, switches the reversing valve, and coordinates the 24V control signals from the thermostat. Because the board carries relays, sensors, and timing logic, a failure can present in many ways: the unit won't start, the system stays stuck in defrost or never defrosts, the compressor short-cycles, or there is no response to a thermostat call. The kit form includes the board and the hardware/connectors needed for a clean retrofit replacement.

Specifications

Compatibility

Designed specifically for the ICP/Tempstar/Heil RHH060L0BA0AAAA heat pump. Confirm the existing board's part number and connector layout against 1183618 before ordering, as control boards are model-specific.

Installation Guide

1. Safety First – Disconnect power at the disconnect and breaker, then verify zero voltage at the board with a multimeter.
2. Access – Remove the service panel to expose the control board.
3. Document – Photograph every plug and wire location on the old board; note any DIP switch or jumper settings.
4. Remove – Unplug each connector, release the board standoffs or screws, and lift the old board out.
5. Install – Mount the new board, transfer DIP/jumper settings, and reconnect every plug per your photo until fully seated.
6. Test – Restore power and run a full heat and cool cycle, confirming proper sequencing and defrost operation.

Signs You Need a Replacement

• No response to a thermostat call despite good 24V power
• System stuck in defrost or never defrosting in heat mode
• Compressor short-cycling or erratic relay operation
• Visible burnt traces, scorched relays, or blown components on the board
