Overview
This OEM integrated furnace control board (kit part number 1183618) is the brain of your ICP / Tempstar / Heil RGS244HEAA0AAAA gas furnace. It manages the ignition sequence, blower and inducer timing, gas valve operation, and onboard safety monitoring. When the control board fails, the furnace may lock out, fail to ignite, short cycle, blow no heat, or run the blower continuously. A flashing LED diagnostic code on the existing board is the most common sign that a replacement is needed. This is a complete factory kit supplied with the correct firmware and connector layout for a true plug-in replacement.

Compatibility
Engineered as a direct OEM replacement for the ICP Tempstar Heil model RGS244HEAA0AAAA furnace. ICP manufactures equipment under multiple brand labels (Tempstar, Heil, Comfortmaker, Arcoaire), so this control board fits the equivalent units across those families. Always match your existing board's part number and connector layout before installing.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker. Verify zero voltage with a multimeter.
- Access — Remove the furnace blower compartment service panel.
- Document — Photograph every wire and connector on the existing board before disconnecting anything.
- Remove — Unplug all wiring harnesses, release the mounting standoffs or screws, and lift out the old control board.
- Install — Mount the new board on the same standoffs and reconnect every harness exactly as documented in your photos.
- Test — Restore power, run a heat call, and confirm the full ignition, inducer, and blower sequence completes with no fault codes.
Signs You Need a Replacement
- Furnace will not ignite or repeatedly locks out
- Blower or inducer motor runs constantly or never starts
