ICP Fan Motor for WAHM304A2 — ECM X-13 1/3 HP Motor Control | Ships Today

Overview

This is a genuine OEM ECM X-13 blower motor control module (part number 1185282) for the ICP/Heil/Tempstar WAHM304A2 air handler. The X-13 is a 1/3 HP constant-torque electronically commutated motor control that drives the indoor blower at programmed torque taps for quiet, efficient airflow across heating and cooling modes. A failing X-13 control typically causes the blower to run erratically, stop entirely, or fail to respond to the thermostat call. Because the control electronics are integrated with the motor, replacing this assembly restores full variable-tap blower operation.

Specifications

Compatibility

Direct OEM fit for the ICP/Heil/Tempstar WAHM304A2 air handler and WAHM-series fan coils specifying the 1/3 HP X-13 blower control. Verify the horsepower rating and torque-tap wiring of your existing motor before installing.

Installation Guide

1. Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter before servicing.
2. Access — Remove the blower compartment service panel.
3. Document — Photograph the motor mount, blower wheel position, and all wire harness and torque-tap connections.
4. Remove — Disconnect the power and control harness, loosen the blower wheel set screw, and slide the motor out of the housing.
5. Install — Mount the new X-13 control, reinstall the blower wheel at the same depth, and reconnect the harness and torque taps per your photo.
6. Test — Restore power and confirm smooth blower ramp-up on a thermostat call in both heat and cool.
