ICP Furnace Control Board Kit for RGS244HSEA0AAAA — OEM 1183618 | Ships Today

Overview

This is the genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS244HSEA0AAAA. The integrated furnace control board is the brain of the unit — it manages the ignition sequence, monitors safety limits and flame, sequences the inducer and blower motors, and coordinates the 24V control circuit between the thermostat and the major components. When this board fails, the system typically will not start, locks out on ignition, short-cycles, or runs the blower continuously. Supplied as a complete kit for a direct, reliable replacement.

Specifications

Compatibility

Engineered as a direct-fit replacement for the ICP Tempstar Heil RGS244HSEA0AAAA. Always confirm the part number printed on your existing board (1183618) before ordering, as control boards are revision-specific.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the service panel to expose the control board.
3. Document — Photograph every wire and connector location before disconnecting anything.
4. Remove — Unplug the harness connectors, remove the mounting screws/standoffs, and lift out the failed board.
5. Install — Mount the new board on the same standoffs and reconnect each harness exactly per your photos.
6. Test — Restore power, run a heat call, and confirm the full ignition and blower sequence completes without fault codes.
