Overview

This genuine OEM control board kit (PN 1183618) is the integrated furnace control (IFC) for the ICP Tempstar Heil RGS120LRAA0AAA gas furnace. The control board is the brain of the furnace — it manages the ignition sequence, monitors safety limits and the pressure switch, sequences the inducer and blower motors, and reads the flame sensor. When the board fails, the furnace may not respond to the thermostat, lock out, blow cold air, or run blower and inducer erratically. Supplied as a complete kit for a direct, reliable replacement.

Document — Photo every connector and wire position on the old board before disconnecting — this is critical for a control board.
Remove — Unplug all connectors, remove the mounting screws or standoffs, and lift out the old board.

Test — Restore power, call for heat, and verify the full ignition and blower sequence completes normally.

Frequently Asked Questions

Does this Control Board fit my ICP RGS120LRAA0AAA — OEM Replacement | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS120LRAA0AAA — 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 RGS120LRAA0AAA — 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?
