Overview
This is the genuine OEM furnace control board kit (ICP part #1183618) for the ICP/Tempstar/Heil RGS214SDAA0AAAA gas furnace. The control board is the brain of the furnace — it manages the ignition sequence, sequences the inducer motor, igniter, gas valve, and blower, monitors safety limits and flame sense, and runs the on-board diagnostic LED. When the board fails, the furnace may not respond to a heat call at all, may light then drop out, may run the blower continuously, or may flash a hard-lockout fault code. Supplied as a kit for a complete, reliable replacement.

Compatibility
Engineered as a direct-fit replacement for the ICP/Tempstar/Heil/Comfortmaker RGS214SDAA0AAAA furnace. Match the connector layout and harness plugs to your existing board before installing. Note any DIP-switch or jumper settings on the old board and replicate them on the new one.
Installation Guide
- Safety First — Disconnect furnace power at the switch/breaker and shut the gas, then verify zero voltage with a multimeter.
- Access — Remove the control-compartment service panel.
- Document — Photograph every harness connection and record all DIP-switch/jumper positions before unplugging.
- Remove — Unplug each connector, release the board standoffs/screws, and lift out the old control.
- Install — Mount the new board, set the DIP switches to match the original, and reconnect every harness exactly per your photos.
- Test — Restore gas and power, run a full heat cycle, and confirm proper ignition sequence with no fault codes on the diagnostic LED.
Signs You Need a Replacement
- No furnace response to a thermostat heat call
- Hard-lockout fault code flashing on the diagnostic LED
