ICP Fan Coil Control Board for WAHM244A1 — OEM Direct Fit | Ships Today

Overview

This is an OEM fan coil control board (part number 1172975) for the ICP WAHM244A1 fan coil / air handler. The control board is the brain of the unit — it interprets thermostat calls, sequences the blower motor and electric heat stages, manages safety interlocks, and coordinates the 24V control circuit. When the board fails, the air handler may stop responding to the thermostat, run the blower continuously, fail to energize heat, or behave erratically. Visible scorch marks, blown fuses, burnt relays, or a board that will not power up are clear indicators that the control board has failed and needs replacement.

Compatibility

Built as a direct-fit replacement for the ICP WAHM244A1 fan coil. This control board is shared across many ICP-family air handlers sold under the Tempstar, Heil, and Comfortmaker brands. Confirm OEM part number 1172975 against your existing board before ordering.

Installation Guide

1. Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter before servicing.
2. Access — Remove the control compartment service panel.
3. Document — Photograph every wire harness and terminal connection on the board before disconnecting anything.
4. Remove — Unplug all connectors, release the mounting standoffs or screws, and lift out the failed board.
5. Install — Seat the new board on the mounts and reconnect every harness and terminal exactly per your photos.
6. Test — Restore power, run a heat and a fan call, and confirm the board sequences the blower and heat correctly.
