Overview

This OEM integrated furnace control board (circuit board P/N 1178358 with ignition control module P/N 1177661) is the brain of your ICP / Heil / Tempstar WPG3364090RKC1 packaged gas-electric unit. It manages the ignition sequence, monitors flame and pressure-switch feedback, sequences the inducer and blower, and protects the system through built-in safety lockouts. A failed control board is one of the most common causes of a furnace that will not start, short-cycles, or locks out intermittently. The board operates on a 24V control circuit and communicates with the igniter, gas valve, pressure switch, and limit controls.

Frequently Asked Questions

Does this Control Board fit my ICP WPG3364090RKC1 — Integrated Ignition Control Module | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WPG3364090RKC1 — Integrated Ignition Control 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 WPG3364090RKC1 — Integrated Ignition Control 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?
