Overview

This OEM integrated furnace control board kit (OEM 1183618) is the brain of your ICP / Heil / Tempstar RGS240HEEA0AAAA gas furnace. It manages the entire heating sequence — igniter timing, gas valve operation, inducer and blower motor staging, flame sensing, and safety lockouts — while monitoring the limit and pressure switches. The board also drives the system's diagnostic LED fault codes that techs use to troubleshoot. Control boards fail from power surges, corroded relays, cracked solder joints, and heat fatigue. When the board fails the furnace may be completely dead, stuck in a single mode (blower runs constantly), or flash error codes that don't correspond to any real fault. Because the board ties every component together, an intermittent or partial failure can mimic problems with the igniter, gas valve, or blower.

Compatibility

Supplied as a kit for the ICP / Heil / Tempstar / Comfortmaker RGS240HEEA0AAAA gas furnace and related platform models. Confirm the board's connector layout and part number against your original before installing — control boards are model-specific.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
Access — Remove the furnace control compartment service panel.
Document — Photograph every wire harness and connector position before disconnecting — this is critical for a multi-connector board.
Remove — Unplug all harnesses, remove the mounting screws, and lift out the old board.
Install — Mount the new board, transfer each harness to its matching connector exactly per your photos, and set any DIP switches/jumpers to match the original.
Test — Restore power and run a full heat cycle; confirm normal ignition, blower operation, and a steady diagnostic LED with no fault codes.

Signs You Need a Replacement

Furnace completely unresponsive to a call for heat
Blower or inducer runs constantly or won't start
Erratic or nonsensical diagnostic fault codes
Visible burn marks, corroded relays, or scorched traces on the board

Frequently Asked Questions

Does this Control Board fit my ICP RGS240HEEA0AAAA — 24V | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS240HEEA0AAAA — 24V | 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 RGS240HEEA0AAAA — 24V | 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?
