Overview

This OEM integrated control board is the electronic brain of your ICP WPG3304040LKC1 system. It manages the heating sequence — inducer start, pressure-switch proof, igniter warm-up, gas valve timing, flame sensing, and blower on/off delays — while coordinating the cooling call to the contactor. This listing covers the integrated circuit board (OEM 1178358) and its ignition control module (OEM 1177661), which together govern safe, timed ignition. When the board fails, the unit may lock out on ignition, fail to energize the igniter or gas valve, leave the blower running continuously, or show diagnostic LED fault codes. Boards commonly fail from power surges, moisture, corroded connectors, or burnt relays. Inspect the wiring harness and grounding before replacing, since a board failure is often a symptom of an upstream electrical fault.

Frequently Asked Questions

Does this Control Board fit my ICP WPG3304040LKC1 — Integrated Ignition Control | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WPG3304040LKC1 — Integrated Ignition 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 WPG3304040LKC1 — Integrated Ignition 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?
