Overview

This is a genuine OEM integrated furnace control board (part number 1184783) for the ICP/Tempstar/Heil WFAR040A030A1 furnace. The control board is the brain of the furnace — it sequences the draft inducer, hot surface igniter, gas valve, and blower while monitoring the pressure switch, limit switches, and flame sensor for safe operation. A failed control board produces a wide range of symptoms: no response to the thermostat, an inducer or blower that will not start, an igniter that never energizes, or a board that locks out and flashes a diagnostic fault code. Boards commonly fail from voltage surges, cracked solder joints, blown onboard fuses, or burnt relay contacts. Replacing with the correct OEM board restores the full ignition and safety sequence.

Frequently Asked Questions

Does this Control Board fit my ICP WFAR040A030A1 — Integrated Control | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WFAR040A030A1 — Integrated 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 WFAR040A030A1 — Integrated 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?
