Overview

The integrated furnace control board is the brain of the WPG3364090LKC1 packaged unit. It sequences the entire heating cycle — inducer start, pressure-switch proving, hot-surface igniter warm-up, gas-valve timing, flame sensing, and blower on/off delays — while managing the 24V thermostat signals and safety lockouts. This OEM assembly pairs the circuit board (1178358) with the ignition control module (1177661) so the board correctly drives the igniter and verifies flame. A failed board typically shows up as no ignition, short cycling, blower running constantly, or a flashing diagnostic LED fault code.

Frequently Asked Questions

Does this Control Board fit my ICP WPG3364090LKC1 — Integrated Ignition Control | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WPG3364090LKC1 — 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 WPG3364090LKC1 — 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?
