Overview

This OEM control board kit (part 1183618) is the integrated furnace control for the ICP / Tempstar / Heil RGS213LSCA0AAAA. The control board is the brain of the furnace — it manages the ignition sequence, monitors safety switches and the flame sensor, sequences the inducer and blower motors, and stores diagnostic fault codes. When the board fails, the furnace can lose all function, behave erratically, or lock out on faults that have nothing to do with the components being blamed. Common symptoms include a completely dead furnace with no LED activity, a blower that runs constantly or not at all, intermittent ignition, visible burn marks or scorched relays on the board, and error codes that persist after every other component checks out. This kit ships as the OEM-specified assembly for a clean, complete replacement.

Compatibility

Direct OEM replacement for the ICP / Tempstar / Heil RGS213LSCA0AAAA furnace. Control boards are model-specific — compare the board part number and connector layout against your existing control before installing, and note your DIP switch or jumper settings so you can mirror them on the new board.

Installation Guide

Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter before opening the control compartment.
Access — Remove the furnace service panel to expose the control board and its wiring harnesses.
Document — Photograph every harness connector and record all DIP switch and jumper positions before unplugging anything.
Remove — Disconnect the harnesses, release the board standoffs or screws, and lift the old board out.
Install — Mount the new board, transfer DIP/jumper settings to match, and reconnect each harness to the matching keyed connector per your photos.
Test — Restore power and run a full heat cycle, confirming proper ignition, blower sequencing, and a clear diagnostic LED with no fault codes.

Signs You Need a Replacement

Furnace completely dead with no diagnostic LED.
Blower runs constantly or never starts despite good motor and limits.
Visible scorch marks, burned traces, or failed relays on the board.
Persistent fault codes after all other components test good.

Frequently Asked Questions

Does this Control Board fit my ICP RGS213LSCA0AAAA — OEM | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS213LSCA0AAAA — OEM | 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 RGS213LSCA0AAAA — OEM | 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?
