ICP Control Board Kit for RGS102STBB0AAA — OEM 1183618 Furnace Board | Ships Today

Overview

This is the genuine OEM integrated furnace control board kit for the ICP / Tempstar / Heil RGS102STBB0AAA gas furnace, supplied as OEM part 1183618 (KIT CONTROL BOARD). The control board is the brain of the furnace: it sequences the inducer, igniter, gas valve, and blower, monitors safety limits and flame sensing, and communicates fault codes through its onboard diagnostic LED. When the board fails, the furnace may not respond to the thermostat at all, may flash error codes, or may lock out intermittently. Because it is a complete kit, it includes the hardware and mounting needed for a clean OEM-grade replacement.

Specifications

Compatibility

Engineered as the factory control board for the ICP / Tempstar / Heil RGS102STBB0AAA furnace. Always match the OEM part number printed on your existing board, as control boards are model-specific and not interchangeable across furnace families.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker. Verify zero voltage with a multimeter.
2. Access — Remove the furnace control compartment service panel.
3. Document — Photo every wire and connector on the existing board before disconnecting anything.
4. Remove — Unplug each harness, remove the board mounting screws, and lift out the old board.
5. Install — Mount the new board, then transfer every connector to the matching terminal exactly per your photo.
6. Test — Restore power, call for heat, and verify the full ignition and blower sequence with no fault codes on the diagnostic LED.

Signs You Need a Replacement

• Furnace completely unresponsive to thermostat heat calls
• Diagnostic LED dark or flashing a hard-fault code
• Blower or inducer runs continuously or not at all
