Overview
This is a genuine OEM 1/2 HP blower motor (part #1188128) for the ICP/Tempstar/Heil WPH4244000RKB1 packaged heat pump. The blower motor drives the indoor air-handling wheel that pushes conditioned air through the supply ductwork on both heating and cooling cycles. A worn or failed blower motor is one of the most common causes of weak airflow, hot-and-cold rooms, and overheating equipment. Typical failure symptoms include a motor that hums but won't spin, loud bearing noise or squealing, a burning smell, intermittent operation as the internal overload trips on heat, or no airflow at all from the registers.

Installation Guide

- Remove — Loosen the wheel set screw, disconnect the leads, unbolt the motor from the housing, and slide the blower wheel off the old shaft.
- Install — Transfer the blower wheel to the new motor at the same depth, mount the motor, and reconnect the leads per your photo.
- Test — Restore power and verify smooth, quiet rotation with strong airflow at the registers.
