Overview

This OEM control board kit (part 1183618) for the ICP / Tempstar / Heil RGS102LSAA0AAA gas furnace is the integrated furnace control (IFC) that orchestrates the entire heating sequence — managing the inducer, igniter, gas valve, blower timing, and safety interlocks such as limit and pressure switches. The board reads the thermostat call and sequences each component in the correct order, and its onboard diagnostic LED flashes fault codes for troubleshooting. Control boards fail from voltage surges, overheating, corroded relays, and cracked solder joints. Symptoms include a completely dead furnace, no inducer or blower operation, ignition that never starts, blower running continuously or not at all, and error/flash codes indicating a control fault.

Frequently Asked Questions

Does this Control Board fit my ICP RGS102LSAA0AAA – OEM Ignition Control | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS102LSAA0AAA – OEM 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 RGS102LSAA0AAA – OEM 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.

How fast does National HVAC Parts ship?
