Overview

This genuine OEM integrated furnace control board (part number 1176943, board number CEPL130438-01) is the brain of the ICP / Heil / Tempstar WFML135D066A1 gas furnace. It sequences the entire heating cycle — energizing the inducer, proving pressure, firing the igniter, opening the gas valve, monitoring flame, and timing the blower on and off delays. It also manages safety lockouts and flashes diagnostic fault codes via its onboard LED. When the board fails from power surges, corrosion, cracked solder joints, or burnt relays, the furnace may ignore the thermostat, fail to ignite, lock out, or run the blower continuously. A new board restores correct, safe ignition sequencing and diagnostics.

Frequently Asked Questions

Does this Control Board fit my ICP WFML135D066A1 — OEM CEPL130438-01 | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WFML135D066A1 — OEM 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 WFML135D066A1 — OEM 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?
