Overview

This is the OEM integrated furnace control board kit (part number 1183618) for the ICP Tempstar Heil RGS091STCB0AAA gas furnace. The control board is the brain of the furnace — it manages the ignition sequence, monitors safety limits and flame sensing, sequences the inducer and blower motors, and reports fault codes through its onboard diagnostic LED. When this board fails the furnace will typically lock out, fail to ignite, short-cycle, or run the blower continuously. Because it ships as a complete kit, it includes the mounting hardware and wiring connectors needed for a clean, direct replacement.

Frequently Asked Questions

Does this Control Board fit my ICP RGS091STCB0AAA — OEM 1183618 Integrated Furnace Control | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS091STCB0AAA — OEM 1183618 Integrated Furnace 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 RGS091STCB0AAA — OEM 1183618 Integrated Furnace 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?

Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
