Overview

This OEM control board kit (part #1183618) is the integrated furnace control (IFC) brain for the ICP/Tempstar/Heil RGS150LSCA0AAAA gas furnace. It sequences the entire heat and cool cycle: it powers the inducer, runs the pre-purge, energizes the hot surface igniter, opens the gas valve, monitors the flame sensor, and times the blower on/off delays. It also reads the pressure switch and limit safeties and flashes diagnostic fault codes via an onboard LED. When the board fails, the furnace may show no response on a heat call, short-cycle, run the blower continuously, or display an error code that does not clear — symptoms that mimic many other failures, so verify with the diagnostic LED before replacing.

Frequently Asked Questions

Does this Control Board fit my ICP RGS150LSCA0AAAA | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS150LSCA0AAAA | 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 RGS150LSCA0AAAA | 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?
