Overview
This is the genuine OEM Control Board Kit (part #1183618) for the ICP / Tempstar / Heil RGS180LSEA0AAAA gas furnace. The integrated furnace control board is the brain of the unit — it sequences ignition, monitors safety limits and flame, controls the inducer and blower motors, and manages the 24V thermostat call. When this board fails, the furnace typically will not start, locks out after a few ignition attempts, or runs the blower continuously. Installing the correct OEM board restores reliable, code-compliant operation without guesswork. This is supplied as a kit, so it includes the board and the hardware needed for a direct replacement of the original.

Compatibility
Designed for the ICP Tempstar Heil RGS180LSEA0AAAA furnace. ICP manufactures under several brand names, so this board is also found in matching Comfortmaker and Day & Night equipment that uses the same control. Always confirm the printed control number on your existing board before ordering.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then 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 the wire harnesses, release the board mounting standoffs/screws, and lift out the old control.
- Install — Mount the new board on the same standoffs and reconnect each harness exactly per your photos.
- Test — Restore power, initiate a heat call, and confirm proper ignition, flame sense, and blower sequencing.
Signs You Need a Replacement
- Furnace fails to ignite or locks out after repeated ignition attempts.
- Blower runs constantly or never engages on a heat call.
- No response to the thermostat despite 24V present at the board.
