Overview

This genuine ICP integrated control board (OEM 1178358) with ignition control module (OEM 1177661) is the brain of the packaged unit. It sequences the entire heating cycle — energizing the inducer, monitoring the pressure switch, timing the hot-surface igniter warm-up, opening the gas valve, proving flame through the flame sensor, and controlling blower on/off delays. It also manages safety lockouts and flashes diagnostic fault codes through its LED. When this board fails, symptoms range from no ignition and intermittent no-heat to blower or inducer relays that stick or never energize. This is the exact OEM control board and ignition module set fitted to the ICP / Tempstar / Heil WPG3604115RKC1.

Frequently Asked Questions

Does this Control Board fit my ICP WPG3604115RKC1 — Ignition Control Module | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WPG3604115RKC1 — 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 WPG3604115RKC1 — 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?
