ICP Furnace Control Board Kit for RGS213SDCA0AAAA — OEM | Ships Today

Overview

This is the OEM control board kit (Part No. 1183618) for the ICP RGS213SDCA0AAAA gas furnace. The integrated furnace control board is the brain of the appliance — it manages the ignition sequence, sequences the inducer and blower motors, monitors the limit and pressure switches and flame signal, and runs all safety lockouts. The kit includes the board and the hardware needed for a complete replacement. When the board fails, the furnace may be completely dead, fail to ignite, blow cold air, run the blower continuously, or flash diagnostic fault codes from the onboard LED.

Compatibility

Direct-fit replacement kit for the ICP, Tempstar, Heil, and Comfortmaker RGS213SDCA0AAAA furnace. Control boards are platform-specific — match the OEM kit number and compare the board's connector layout to the original before installing.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the control-compartment panel to expose the existing board.
3. Document — Photograph every wire harness and connector position before disconnecting anything.
4. Remove — Unplug each connector, remove the mounting screws, and lift out the old board.
5. Install — Mount the new board from the kit, transfer each connector to the matching terminal per your photos, and seat the harnesses fully.
6. Test — Restore power, run a full heat call, and watch the diagnostic LED to confirm a clean ignition and blower sequence with no fault codes.

Signs You Need a Replacement

• Furnace is completely unresponsive with no display or LED activity
