Overview

This OEM fan coil control board (part #1172975) is the central logic board for your ICP WAHM364A1 fan coil air handler. It receives 24V thermostat calls, sequences the blower and any electric heat, drives the relays, and manages the X-13 ECM motor tap signals to deliver the correct airflow for fan, cooling, and heating modes. When the board fails, the symptoms vary widely: the blower will not start on a call, electric heat stages do not energize, the fan runs continuously or not at all, or the unit is completely unresponsive even with good 24V power present. Power surges, lightning, moisture intrusion, and failed onboard relays are the usual causes. Visible scorch marks, a cracked relay, or a burnt smell on the board confirm the failure.

Frequently Asked Questions

Does this Control Board fit my ICP WAHM364A1 - OEM Replacement | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WAHM364A1 - OEM Replacement | 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 WAHM364A1 - OEM Replacement | 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?
