ICP Blower Motor for WPG4304060LKA1 — 1/2 HP X-13 ECM | Ships Today

Overview

This is a genuine OEM 1/2 HP X-13 blower motor (part number 1186863) for the ICP/Tempstar/Heil WPG4304060LKA1 packaged gas unit. The X-13 is a constant-torque ECM (electronically commutated motor) that drives the indoor blower wheel, moving conditioned air through the supply ductwork. Unlike older PSC motors, the X-13 maintains a programmed torque across changing static pressure, delivering quieter operation and lower electrical draw. Common failure symptoms include the blower failing to start, intermittent operation, overheating and thermal cutout, unusual humming or grinding, or weak airflow that triggers high-limit lockouts on the furnace.
