Westinghouse 621829 Air Handler Motor 1/5 Hp 3-speed

Product Description

The WESTINGHOUSE 621829 is a 3-speed indoor air handler motor rated at 1/5 HP and 230 volts AC at 60 Hz. It is designed to drive the blower assembly inside residential or light commercial air handler units, circulating conditioned air through the duct system. Licensed HVAC technicians install this motor as a direct replacement when the original blower motor fails due to bearing wear, winding failure, or thermal cutout fatigue. The 3-speed winding configuration allows the installer to match airflow to the system's static pressure and tonnage requirements without additional controls.

This motor is suited for indoor air handler applications in split-system and package unit configurations operating on 230-volt single-phase power. It is typically found in residential forced-air systems where a multi-speed PSC-type blower motor is specified. The 3-speed design provides flexibility for low, medium, and high airflow settings, making it adaptable to a range of duct layouts and comfort zoning setups. Installation is performed during scheduled maintenance or as an emergency replacement when the existing motor fails thermal or amp-draw diagnostics.

Key Features

• 1/5 HP output rating suitable for residential air handler blower duty
• 3-speed winding configuration for flexible airflow adjustment
• 230-volt AC operation at 60 Hz matches standard residential supply voltage
• Designed specifically for indoor air handler applications

Compatibility

Designed as an OEM-style replacement motor for indoor air handler units requiring a 1/5 HP, 3-speed, 230-volt AC, 60 Hz blower motor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the air handler before removing the existing motor. Verify that shaft diameter, rotation direction, mounting configuration, and speed-tap wiring match the replacement motor before energizing. Follow applicable local codes and the system manufacturer's wiring diagram when reconnecting speed-tap leads.
