ICP Fan Motor for WAHM304A1 — 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 WAHM304A1 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 in heating and cooling. A failing X-13 control commonly causes the blower to run erratically, stop completely, or ignore the thermostat call. Since 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 WAHM304A1 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.
