Overview

This is the OEM integrated furnace control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS180STCA0AAAA gas furnace. The control board is the brain of the furnace — it manages the ignition sequence, monitors safety circuits, sequences the inducer and blower motors, and switches the 24V signals to the gas valve and igniter. When this board fails the furnace typically will not start, locks out on repeated ignition attempts, or behaves erratically with intermittent no-heat calls. It operates on a 24V control circuit and includes the required mounting and wiring components shipped as a complete kit.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, verify zero voltage with a multimeter, and shut off the gas supply.
Access — Remove the furnace blower-compartment service panel to expose the control board.
Document — Photograph every wire and connector position on the board before disconnecting anything.
Remove — Unplug the wiring harnesses and spade connectors, release the board mounting tabs/screws, and lift the old board out.
Install — Mount the new board, transfer all connectors exactly per your photos, and seat each plug fully.
Test — Restore gas and power, initiate a heat call, and verify the full ignition sequence and blower operation. Check the diagnostic LED for fault codes.

Frequently Asked Questions

Does this Control Board fit my ICP RGS180STCA0AAAA — OEM Kit 1183618 | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS180STCA0AAAA — OEM Kit 1183618 | 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 RGS180STCA0AAAA — OEM Kit 1183618 | 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?
