ICP ECM X-13 Motor Control 1/2 HP for WJH342000K000A2 — Blower Motor | Ships Today

Overview

This genuine OEM ECM X-13 motor control (part #1185846) is the 1/2 HP variable-speed blower motor for the ICP/Heil/Tempstar WJH342000K000A1/A2 air handler. The X-13 is a constant-torque electronically commutated motor that holds a programmed airflow across changing static pressure, delivering quieter operation and lower energy use than a standard PSC motor. When this motor fails you typically lose all indoor airflow — no heat, no cooling, and no air at the registers even though the outdoor unit may be running. Because it is an integrated motor-and-control assembly, the electronic module is matched to the motor and replaced as one unit.
