ICP ECM X-13 Blower Motor Control for WJA336000K000A1 — 1/2 HP | Ships Today

Overview

This OEM ECM X-13 motor control (part 1185844) is a 1/2 HP constant-torque blower motor used to move conditioned air through the furnace or air handler. The X-13 ECM platform delivers programmed airflow with higher efficiency and quieter operation than a standard PSC motor. A failing ECM blower causes weak or no airflow, intermittent shutdowns, unusual noise, or a motor that runs hot and cycles on thermal overload. Because the control module and motor are matched, replacing the X-13 control restores proper programmed airflow.
