Westinghouse 621939 Indoor Blower Motor 1/3 Hp 208/230V

Product Description

The WESTINGHOUSE 621939 is an indoor blower motor rated at 1/3 HP and designed for operation at 208/230 volts. It circulates conditioned air through the air-handling section of a packaged heat pump unit, maintaining airflow across the indoor coil during both heating and cooling cycles. Licensed HVAC technicians install this motor as a direct replacement in field-service situations where the original motor has failed due to winding breakdown, bearing wear, or thermal overload. The 1/3 HP rating and dual-voltage compatibility at 208/230 volts make it well suited to the residential and light-commercial packaged equipment it was engineered for.

This motor is specified for use in 10 SEER and 12 SEER single packaged heat pump systems. Packaged units house all refrigeration and air-handling components in a single outdoor cabinet, and the indoor blower section moves return air across the indoor coil before distributing it through the duct system. This replacement motor restores proper airflow performance in units where the original blower motor has reached end of service life.

Key Features

• Rated at 1/3 HP for reliable air movement in packaged heat pump blower assemblies
