Overview

The ICP integrated furnace control board kit (OEM part 1183618) is the brain of the RGS150LDCB0AAAA gas furnace. It manages the entire heating sequence — inducer startup, hot surface igniter timing, gas valve operation, flame sensing, and blower fan-on/fan-off delays — while continuously monitoring the limit and pressure safety switches. When the board fails, the furnace may not respond to thermostat calls, may lock out on ignition or flame faults, or may leave the blower running constantly. This kit ships with the matched control board and mounting hardware so you can restore full sequencing and diagnostics in a single service visit.

Test — Restore gas and power, run a full heat cycle, and verify proper ignition, flame sensing, and blower on/off timing with no fault codes.

Frequently Asked Questions

Does this Control Board fit my ICP RGS150LDCB0AAAA — OEM Replacement | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS150LDCB0AAAA — OEM Replacement | 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 RGS150LDCB0AAAA — OEM Replacement | 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?
