Dayton 4YU23 HVAC control motor
The Dayton 4YU23 is a permanent split capacitor motor rated at 1/6 hp and 1140 RPM for 115 V AC single-phase supply. It carries a 48Z frame and a 1.0 service factor with automatic thermal protection and Class B insulation for continuous duty.
Installation and common issues
The motor fits the 48Y frame pattern and offers CW/CCW rotation, so wiring to the existing capacitor and reversing leads is straightforward. Installers should note the unit is not usable at 200 V or 208 V and must stay within the 40 °C maximum ambient temperature.
Who this suits and who should look elsewhere
This motor suits technicians replacing 4HZ36, 4HZ38, 4HZ40, 4HZ42, 5DVR9 or 5DVT1 models in fan and blower assemblies. Buyers who need a different horsepower, speed, voltage or frame size should look at other models.

Questions about this item
How do I verify the 4YU23 motor is running correctly after installation?
Confirm the shaft rotates at 1140 RPM in either CW or CCW direction, draws no more than 2.2 A at 115 V, and the housing stays below 40 °C ambient during continuous duty.
What comes with the 4YU23 and what must I source separately?
The motor itself is supplied; you must provide a compatible run capacitor, mounting hardware for the 48Y frame, and the 115 V single-phase supply wiring.
Which replacement numbers does the 4YU23 cover so I pick the right one?
It directly replaces 4HZ36, 4HZ38, 4HZ40, 4HZ42, 5DVR9 and 5DVT1; match your original part number to that list.
