Overview
This OEM control board kit (part 1183618) is the integrated furnace control (IFC) brain of the ICP / Tempstar / Heil RGS150SEAA0AAAA gas furnace. It sequences the entire heat cycle — inducer start, pressure-switch proving, hot surface igniter warm-up, gas valve energizing, flame sensing, and blower timing — while monitoring safety limits and reporting diagnostic flash codes. When the board fails, the furnace can present as completely dead, stuck in a single stage, short-cycling, or locking out even when the igniter, valve, and switches are all good. Replacing a degraded board restores reliable, safe ignition and proper blower on/off delays.

Compatibility

Installation Guide
- Safety First — Disconnect power at the switch and breaker. Verify zero voltage with a multimeter before touching the board.
- Access — Remove the blower-compartment service panel.
- Document — Photograph every wire and connector on the existing board before removing anything.
- Remove — Unplug all harnesses, release the board mounting screws/standoffs, and lift the old board out.
- Install — Mount the new board, then transfer each connection exactly per your photos, confirming low-voltage terminals match.
- Test — Restore power, run a full heat cycle, and confirm normal sequencing with no fault flash codes.
Signs You Need a Replacement
- Furnace is completely unresponsive with no LED activity on the board.
- Erratic operation, short-cycling, or blower that won't shut off.
- Repeated lockouts even after igniter, gas valve, and switches test good.
- Visible burnt traces, scorched relays, or corrosion on the board.
