Overview

This genuine OEM furnace control board (part number 1178358) paired with the ignition control module (part number 1177661) is the brain of the ICP/Tempstar/Heil WPG3604115LKC1. It sequences the entire heat cycle — energizing the inducer, proving the pressure switch, powering the hot surface igniter, opening the gas valve, monitoring flame, and timing the blower on and off — while watching limit and rollout safeties throughout. A failed board produces erratic or no operation: blower running constantly, no ignition sequence, flashing fault LEDs, or a completely dead furnace. The board's diagnostic LED makes it the central reference point for troubleshooting the system.

Frequently Asked Questions

Does this Control Board fit my ICP WPG3604115LKC1 — Integrated Ignition Module | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WPG3604115LKC1 — Integrated Ignition Module | 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 WPG3604115LKC1 — Integrated Ignition Module | 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?
