Overview
This is a genuine OEM control board kit, part number 1183618, for the ICP/Heil/Tempstar RGS213HDCA0AAAA gas furnace. The integrated furnace control board is the brain of the furnace — it manages the ignition sequence, sequences the inducer and blower, reads the thermostat call and safety circuits (limit switches, pressure switch, flame sense), and provides diagnostic LED fault codes. When the board fails you may see a completely dead furnace, no response to a thermostat call, blower or inducer that won't run, erratic short cycling, or an LED flashing a hard-lockout code. Because the board ties every component together, a confirmed board failure (after ruling out fuses, transformer, and safeties) calls for a direct OEM replacement to restore correct timing and safety logic.

Compatibility
Built for the ICP RGS213HDCA0AAAA and shared across ICP-family gas furnaces (Heil, Tempstar, Comfortmaker, Arcoaire) that use this control platform. Verify your existing board part number — control boards are model-specific and not interchangeable across timing platforms.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
- Access — Remove the control/blower compartment panel.
- Document — Photograph every wire harness and terminal before disconnecting; label connectors.
- Remove — Unplug the harnesses, release the board standoffs, and lift the old board out.
- Install — Mount the new board on its standoffs and reconnect each harness to the matching terminal per your photos.
- Test — Restore power, call for heat, and watch the LED through a full ignition, heat, and blower cycle.
Signs You Need a Replacement
- Furnace is completely dead and unresponsive to a thermostat call
- Inducer or blower will not energize despite good safeties
- Erratic short cycling or random shutdowns
- Diagnostic LED flashes a control-failure or hard-lockout code
