Overview

This OEM integrated furnace control board is the electronic brain of the ICP Tempstar Heil WPG3424090RKC1 packaged gas unit. It manages the ignition sequence, sequences the inducer and blower motors, monitors flame and pressure-switch safeties, and coordinates the call for heat from the thermostat. Replaces OEM circuit board 1178358 and ignition control module 1177661. When this board fails, the furnace section will not light, will short-cycle, or will lock out on safety even when every other component is healthy. Common failure signs include no inducer start on a heat call, a board with no diagnostic LED activity, scorched relays, or repeated ignition lockouts. The board operates on a 24V control circuit and includes the integrated hot-surface ignition control logic.

Frequently Asked Questions

Does this Control Board fit my ICP WPG3424090RKC1 — Integrated Ignition Control Module | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WPG3424090RKC1 — 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 WPG3424090RKC1 — 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?
