Overview
This is the genuine OEM furnace control board kit (part #1183618) for the ICP/Tempstar/Heil RGS101HSCA0AAA gas furnace. The integrated control board is the brain of the furnace — it manages the ignition sequence, monitors flame, sequences the inducer and blower motors, controls limit and pressure switch inputs, and stores diagnostic fault codes. When this board fails, the furnace will typically not respond to a call for heat, lock out after several ignition attempts, run the blower continuously, or flash an error code on the onboard LED. Because it is supplied as a complete kit, it ships with the mounting hardware needed for a direct replacement.

Compatibility
Designed as a direct-fit replacement for the ICP/Tempstar/Heil RGS101HSCA0AAA furnace. ICP manufactures under several brand names (Tempstar, Heil, Comfortmaker), so this board may carry over to related models in the same platform. Always confirm the printed part number on your existing board matches 1183618 before installing.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the furnace blower/control compartment service panel.
- Document — Photograph every wire and connector position on the existing board before disconnecting anything.
- Remove — Label and unplug each harness connector, then remove the board mounting screws and lift out the old board.
- Install — Mount the new board on the supplied standoffs/bracket and reconnect each harness exactly per your photos.
- Test — Restore power, initiate a heat call, and confirm a clean ignition sequence with no fault codes on the diagnostic LED.
Signs You Need a Replacement
- Furnace ignores the thermostat's call for heat entirely.
- Repeated ignition lockout after 3–5 trial-for-ignition attempts.
- Blower runs constantly or fails to start.
- Diagnostic LED flashing a hard-lockout or control-fault code.
