ICP Fan Coil Control Board for WAHT244A1 — OEM Replacement | Ships Today

Overview

This OEM fan coil control board (part 1172975) is the central logic board that manages your ICP WAHT244A1 air handler. It sequences the blower, processes thermostat calls for heating and cooling, controls any electric heat staging, and protects the unit through its onboard relays and fuse. When the board fails, the system can behave erratically — the blower won't run, electric heat won't energize, the thermostat seems unresponsive even with good 24V power, or the unit short-cycles. Visible signs like scorched traces, a blown onboard fuse, or burnt relay contacts confirm the board needs replacement. A correct OEM board restores the factory control sequence your air handler was engineered for.

Installation Guide

1. Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter.
2. Access — Remove the air handler service panel to expose the control board.
3. Document — Photograph every wire harness and terminal connection before disconnecting.
4. Remove — Unplug the harnesses, release the board standoffs or mounting screws, and lift out the failed board.
5. Install — Seat the new board on the standoffs and reconnect each harness to its matching terminal per your photo.
6. Test — Restore power and confirm the blower, heat, and thermostat calls all sequence correctly.
