Ao Smith EM3729F Condenser Fan Motor 1/3 Hp 208-230V

Product Description

The AO SMITH EM3729F is a totally enclosed condenser fan motor rated at 1/3 horsepower and 1075 RPM, designed for use in air conditioning condensing units. Operating on 208-230 volts, this motor drives the condenser fan blade to move air across the condenser coil, supporting the heat rejection process in the refrigeration cycle. Its totally enclosed construction protects internal windings from outdoor contaminants, moisture, and debris - a critical requirement for motors mounted in exposed condensing unit cabinets. Licensed HVAC technicians typically handle installation and replacement of this component.

This motor is suited for residential and light commercial condensing unit applications where a single-phase, 208-230V power supply is present. It is a direct replacement option for condenser fan motor applications requiring 1/3 HP output at 1075 RPM. The totally enclosed enclosure rating makes it appropriate for outdoor installations where the motor is exposed to weather and airborne particulates common in condenser cabinet environments.

Key Features

• Totally enclosed motor construction protects windings from moisture, dust, and outdoor debris
• 1/3 HP output with 1075 RPM operating speed suited for condenser fan blade loads
• 208-230V single-phase voltage rating covers standard residential and light commercial supply voltages
• Designed for condenser fan duty in air conditioning and refrigeration condensing units

Compatibility

Designed as an OEM-style replacement condenser fan motor for residential and light commercial air conditioning condensing units requiring a totally enclosed 1/3 HP, 1075 RPM, 208-230V motor.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable local codes and manufacturer guidelines. Disconnect and lock out all electrical power to the condensing unit before removing the existing motor or accessing any wiring. Verify that the replacement motor shaft diameter, rotation direction, and mounting configuration match the original unit requirements before completing installation. Capacitor compatibility should also be confirmed prior to energizing the unit.
