Overview

This is the OEM control board kit (part 1183618) for the ICP/Heil/Tempstar RGS300HFAA0AAAA gas furnace. The integrated furnace control board is the brain of the heating system — it sequences ignition, monitors the flame-sense circuit, controls the inducer and blower motors, manages the 24V thermostat inputs, and runs safety lockouts. When it fails you typically see a furnace that is completely dead, blower or inducer that won't run, no ignition, or a diagnostic LED flashing a hard-fault code. This kit includes the board and the hardware needed for a clean swap.

Frequently Asked Questions

Does this Control Board fit my ICP RGS300HFAA0AAAA — Furnace Ignition Control | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS300HFAA0AAAA — Furnace Ignition Control | Ships Today. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the control board on my ICP RGS300HFAA0AAAA — Furnace Ignition Control | Ships Today?

Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.

My HVAC system is completely dead. What could be wrong?

Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.

Is this control board compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP control board?

OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
