Nordyne Intertherm 902346 Blower Motor 3/4 Hp 4 Speed 120V

Product Description

The NORDYNE INTERTHERM 902346 is a 3/4 horsepower, 4-speed, 120-volt blower motor designed for forced-air HVAC systems. It moves conditioned air across the heat exchanger or evaporator coil and delivers it through the duct system. The motor operates on a single-phase, 120-volt supply and provides four selectable speed taps, allowing the installer to match airflow to the system's static pressure and design requirements. Licensed HVAC technicians install and replace this component during routine motor failures, scheduled maintenance, or system refurbishment.

This blower motor is suited for residential forced-air applications where a 3/4 HP, 4-speed, 120-volt motor is specified. It is a direct OEM-style replacement intended for use in air handlers and furnace blower assemblies where the original motor has failed due to bearing wear, winding failure, or thermal overload. The four speed taps allow field selection of the correct CFM for heating, cooling, and continuous-fan operation modes.

Key Features

• 3/4 HP output suitable for residential forced-air blower assemblies
• Four speed taps for field-selectable airflow matching
• 120-volt single-phase operation
