Dayton 4HZ71 HVAC Control Motor PSC 3/4 HP 1100 RPM 115/230V 48Y OAO
A permanent-split-capacitor blower motor delivering 3/4 HP at 1100 RPM on 115/230 V single-phase power for direct-drive HVAC applications
- 3/4 HP PSC motor delivers reliable HVAC airflow
- 115/230 V dual-voltage operation suits most installations
- 1100 RPM single-speed design simplifies blower replacement
- Auto thermal protection prevents overheating during continuous duty
- Replaces OEM models 4HZ31, 4HZ57 and 4HZ59
Product identity
The Dayton 4HZ71 is a single-phase permanent split capacitor motor rated at 3/4 horsepower and 1100 RPM for 115/230 V AC operation. It is designed as a direct-drive blower motor for HVAC systems requiring a 48Y frame open air-over enclosure.
Installation checks
Verify that your application uses a 48Y frame with ring or stud mounting and that the shaft rotation is CCWSE. Confirm the supply voltage matches 115 V or 230 V at 60 Hz and that the ambient temperature will not exceed 40 °C. Ensure the existing capacitor and wiring suit a 10.0 / 5.0 A full-load rating.
Replacement scope
This unit replaces manufacturer numbers 4HZ31, 4HZ57 and 4HZ59, simplifying cross-reference sourcing. Auto-reset thermal protection and continuous duty rating maintain the original safety and runtime behaviour. The all-angle mounting position allows the same installation orientation as the removed motor.

Questions about this item
What components come with the 4HZ71 motor and what must be purchased separately?
The 4HZ71 PSC motor arrives as a complete direct-drive unit with auto thermal protection, Class B insulation and a 48Y frame ring-stud mount; a run capacitor, mounting hardware and wiring are not included and must be sourced separately.
How do I choose between the 115 V and 230 V connections on this dual-voltage motor?
The motor draws 10.0 A at 115 V or 5.0 A at 230 V, so select the voltage that matches your supply and the circuit ampacity available at the installation site.
What does the 1,100 RPM rating mean for airflow once the motor is installed in a blower assembly?
At 1,100 RPM the motor provides a single-speed output suitable for continuous-duty direct-drive blower applications within a 40 °C maximum ambient temperature.
