Overview
This OEM integrated furnace control (IFC) board, supplied as 1183618 (KIT, CONTROL BOARD), is the electronic brain of the ICP / Tempstar / Heil RGS150STCA0AAAA gas furnace. It sequences the entire heating operation: it powers the inducer, proves the pressure switch, energizes the hot surface igniter, opens the gas valve, monitors flame via the flame sensor, and controls blower timing. A failed control board produces a wide range of symptoms — no ignition, no blower, erratic operation, or a blank diagnostic LED. This factory kit includes the board and mounting hardware for a direct replacement.

Installation Guide
- Safety First — Disconnect electrical power to the furnace and verify zero voltage with a multimeter.
- Access — Remove the furnace control/blower compartment panel.
- Document — Photograph every wire and connector position on the old board before disconnecting anything.
- Remove — Unplug all harnesses and low-voltage terminals, remove the board mounting screws, and lift out the old control board.
- Install — Mount the new board, then reconnect every wire exactly per your photos, confirming firm seating on each connector.
- Test — Restore power and run a full heat cycle; verify the diagnostic LED shows a normal code and all components sequence correctly.
Signs You Need a Replacement
- No diagnostic LED, or an LED showing a hard-fault flash code.
- Furnace will not start despite a valid thermostat call.
- Blower or inducer runs continuously or fails to engage.
