ICP ECM X-13 Motor Control for WAPT304A1 — 1/3 HP | Ships Today

Overview

This OEM ECM X-13 blower motor control (ICP part #1185271) is the 1/3 HP electronically commutated motor for the ICP / Tempstar / Heil WAPT304A1 system. Unlike a standard PSC motor, the X-13 ECM uses a built-in electronic control module to hold a programmed, constant-torque airflow across varying static pressure — delivering quieter, more efficient operation and steadier airflow. Failure symptoms include the blower not starting, surging or hunting airflow, the motor running only briefly before shutting down, or fault codes at the control board. ECM failures usually trace to the integrated control module, bearing wear, or moisture intrusion. A genuine OEM X-13 replacement restores the system's programmed airflow profile and efficiency.
