ICP ECM X-13 Blower Motor Control 1/3 HP for WJH324000K000A2 — Ships Today

Overview

This is a genuine OEM ICP ECM X-13 motor control module (part number 1185839), a 1/3 HP variable-speed blower motor control used in ICP, Heil, and Tempstar heat pump air handlers and furnaces. The X-13 is a constant-torque ECM platform that holds programmed airflow as static pressure changes, giving quieter and more efficient blower operation than a standard PSC motor. When the X-13 control fails you typically see no blower operation, intermittent starts, surging or hunting airflow, or a blower fault at the control board. Replacing the control module restores correct CFM staging in both heating and cooling.
