Overview
This genuine ICP/Tempstar/Heil OEM control board kit (part 1183618) is the integrated furnace control (IFC) that manages the entire heating sequence on the RGS213HREA0AAAA. The board reads the thermostat call, runs the inducer and pressure-switch proving sequence, energizes the igniter, opens the gas valve, monitors flame via the sensor, and times the blower on and off delays. It also provides diagnostic LED fault codes and self-protection lockouts. Because the control board is the brain of the furnace, a failed board can cause no-heat, no blower, erratic cycling, or a furnace that ignites but won't stay running. This kit ships with the OEM board and the hardware needed for a direct replacement.

Compatibility
Engineered for the ICP/Tempstar/Heil RGS213HREA0AAAA and supplied as the OEM-specified replacement control for that platform. Confirm the part number 1183618 against your existing board, as integrated furnace controls are model- and revision-specific.
Installation Guide
- Safety First — Disconnect power at the switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the furnace control compartment panel.
- Document — Photograph every connector, wire, and terminal on the old board before disconnecting — wiring placement is critical.
- Remove — Unplug all connectors, remove the board's mounting screws/standoffs, and lift out the old control.
- Install — Mount the new 1183618 board and reconnect each plug and wire exactly per your photo, confirming the line-voltage polarity.
- Test — Restore power, run a full heat cycle, and verify ignition, flame proving, blower timing, and clean LED status with no fault codes.
Signs You Need a Replacement
- No response from the furnace on a heat call (no inducer, no igniter).
- Blower runs continuously or never starts despite proper timing.
- Diagnostic LED is dark, or flashes a hard internal/control fault.
- Burnt spots, scorched relays, or corroded traces visible on the board.
