Overview
This is the genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS244HRFA0AAAA gas/electric package unit. The integrated furnace control board is the brain of the heating section: it manages the ignition sequence, monitors safety limits and pressure switches, controls the inducer and blower motor timing, and coordinates the call for heat from the thermostat. When this board fails, the unit may not ignite, may short-cycle, may run the blower continuously, or may go completely dead with no response to a thermostat call. Common failure symptoms include flashing diagnostic LED fault codes, no inducer or igniter activity on a heat call, blown low-voltage fuses, and intermittent operation as solder joints crack from thermal cycling. Replacing the board with the exact OEM kit restores correct ignition timing and all factory safety logic.

Compatibility
Designed as a direct-fit replacement for the ICP-family RGS244HRFA0AAAA gas/electric package unit and is shared across closely related Tempstar, Heil, and Comfortmaker package units that use the 1183618 control kit. Always confirm the printed part number on your existing board before ordering.
Installation Guide
- Safety First — Disconnect power at the unit disconnect and breaker, then verify zero voltage with a multimeter.
- Access — Remove the control/blower access panel.
- Document — Photograph every wire and connector position on the existing board before disconnecting.
- Remove — Unplug the molex connectors and individual terminals, remove the mounting screws or standoffs, and lift out the old board.
- Install — Mount the new board on the same standoffs and reconnect every wire exactly per your photo.
- Test — Restore power, initiate a heat call, and confirm a normal ignition sequence and no fault codes on the diagnostic LED.
Signs You Need a Replacement
- No ignition sequence — inducer and igniter never energize on a heat call.
- Flashing or steady fault-code LED indicating a board failure.
- Blower runs continuously or never starts.
- Repeated blown low-voltage fuses or intermittent dead unit.
