Overview

This genuine OEM control board kit (ICP part number 1183618) is the brain of your ICP RGS300SRFA0AAAA packaged gas/electric unit. The integrated control board manages the entire ignition sequence — pre-purge, inducer operation, igniter timing, gas valve control, flame sensing, blower on/off delays, and safety lockouts. It constantly monitors limit switches and pressure switches and shuts the system down if a fault is detected. When the board fails you may see no response on a heat call, the unit stuck in lockout, a blower that runs constantly or never starts, error codes flashing on the diagnostic LED, or intermittent operation that defies other repairs. Supplied as a complete kit with the mounting hardware and instructions needed for a clean swap, this board restores full, code-compliant control of both the heating and blower functions.

Frequently Asked Questions

Does this Control Board fit my ICP RGS300SRFA0AAAA — Integrated Ignition | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS300SRFA0AAAA — Integrated Ignition | 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 RGS300SRFA0AAAA — Integrated Ignition | 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.

How fast does National HVAC Parts ship?
