Overview

This genuine OEM control board kit for the ICP / Tempstar / Heil WPG3604090RKC1 packaged gas-electric unit includes the main circuit board (part 1178358) and the ignition control module (part 1177661). Together they are the brain of the unit: managing the heating sequence of operations, sequencing the inducer, hot surface igniter, and gas valve, monitoring the pressure switch and limit safeties, proving flame, and timing the blower on and off. The board also handles the 24V control logic and onboard diagnostics, flashing fault codes through an LED to speed troubleshooting. When the board or ignition module fails, symptoms range from no-heat lockouts and short cycling to a blower that won't run or a unit that ignores the thermostat entirely.

Frequently Asked Questions

Does this Control Board fit my ICP WPG3604090RKC1 — Ignition Control Module | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WPG3604090RKC1 — 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 WPG3604090RKC1 — 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?
