Overview

The RHEEM 51-109845-22 is an Ensite series replacement motor rated at 3/4 horsepower and 115 volts. It is designed for use in HVAC air-handling equipment where the motor drives a blower or fan assembly to move conditioned air through the system. This motor replaces a failed or worn OEM unit and restores proper airflow performance. Licensed HVAC technicians are the primary installers for this type of component. The 115-volt single-phase power supply requirement makes it compatible with standard residential electrical service. This motor is suited for residential HVAC applications where a direct replacement for the original Ensite motor is required. It is typically installed in air handlers, furnaces, or fan coil units that originally shipped with this motor configuration. The 3/4 HP rating addresses mid-range blower load demands common in residential forced-air systems. When the original motor fails due to bearing wear, winding failure, or overheating, this part restores the system to factory specification.
