Overview
This genuine OEM control board kit (part number 1183618, "KIT CONTROL BOARD") is the integrated furnace control for the ICP/Tempstar/Heil RGS150LRCA0AAAA. The board is the brain of the furnace: it manages the ignition sequence, sequences the inducer and blower motors, monitors limit and pressure switches, drives the gas valve, and watches flame sense for every safety interlock. It also flashes diagnostic fault codes through its onboard LED. When the board fails — from power surges, corroded relays, burned traces, or failed flame-sense circuitry — the furnace may not ignite, may run the blower constantly, may short-cycle, or may throw erratic and inconsistent fault codes.

Installation Guide
- Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter.
- Access — Remove the control-compartment service panel.
- Document — Photograph every wire harness and connector position before disconnecting — this is critical for a multi-connector board.
- Remove — Unplug each harness, remove the mounting screws, and lift out the old board.
- Install — Mount the new board, transfer any jumper or dip-switch settings, and reconnect every harness exactly per your photos.
- Test — Restore power and run a full heat cycle, watching the diagnostic LED for a normal sequence.
Signs You Need a Replacement
- Furnace completely unresponsive to thermostat calls
- Blower runs continuously or won't run at all
