HVAC Replacement Motor
The FASCO D364 is a shaded-pole fan and blower motor rated at 1/25 horsepower for single-phase 115 V AC systems. It delivers 30 watts output at 1550 RPM with a 1.8 amp full-load draw, suited to residential air-handling units that specify a 3.3 frame size.
Voltage And Thermal Limits
The motor is not usable at 200 V or 208 V, so it must be wired to a 115 V 60 Hz supply only. Auto thermal protection and Class B insulation guard against overload, while the 40 °C maximum ambient rating defines the hottest operating environment it can tolerate.
Open Enclosure And Stud Mount
An open air-over enclosure relies on the equipment's airflow for cooling, so the motor must sit in the airstream of the blower housing. Steel frame construction and a stud mounting pattern let it bolt directly to the original bracket, and the fixed clockwise rotation (CWLE) matches the OEM fan wheel direction.

Questions about this item
Does the motor's thermal protection require manual resetting after it trips?
No, the motor uses automatic thermal protection that resets itself once the temperature drops back into the safe range.
Is the 1.8 amp full-load current the highest draw I should plan for on a 115 volt circuit?
Yes, the nameplate lists 1.8 A as the full-load amps at 115 V, and the service factor is 1.0, so sustained operation will not exceed that figure.
How hot does the motor housing get when it runs continuously in a 40 °C ambient?
The insulation is Class B, rated for a maximum ambient of 40 °C; the open air-over enclosure relies on airflow from the blower wheel to keep housing temperature within that limit.
