Overview

This OEM integrated furnace control (IFC) board is the original circuit board for the ICP/Heil/Tempstar WFHR040B036A1 gas furnace, part number 1176943 / CEPL130438-01. The board is the brain of the furnace — it sequences the inducer, igniter, gas valve, and blower, monitors the limit and flame-sense circuits, and stores diagnostic fault codes. A failed board produces erratic operation, no response to thermostat calls, or repeated lockouts that no other single part can explain.

Document — Photograph every wire harness and connector position before disconnecting anything.
Remove — Unplug each connector, release the board standoffs or screws, and lift out the old board.

Frequently Asked Questions

Does this Control Board fit my ICP WFHR040B036A1 — OEM 1176943 CEPL130438-01 | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WFHR040B036A1 — OEM 1176943 CEPL130438-01 | 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 WFHR040B036A1 — OEM 1176943 CEPL130438-01 | 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?
