ICP ECM X-13 Blower Motor Control for WJH336000K000A1 – 1/2 HP | Ships Today

Overview

This is a genuine OEM ECM X-13 blower motor control (Part #1185845), rated 1/2 HP, for the ICP/Tempstar/Heil WJH336000K000A1 air handler. The X-13 is a constant-torque electronically commutated motor that drives the indoor blower wheel, moving conditioned air through the duct system. Compared to a standard PSC motor, the X-13 delivers steadier airflow and lower electrical consumption across multiple programmed taps. When this motor fails, the system loses indoor airflow entirely or runs erratically, leading to poor comfort, frozen coils, or overheating safety lockouts.
