It is a \u003cstrong\u003ePermanent Split Capacitor (PSC)\u003c\/strong\u003e design built for \u003cstrong\u003eair-over\u003c\/strong\u003e duty, meaning the condenser fan's own airflow carries the heat away from the motor. The shell is \u003cstrong\u003eTotally Enclosed Air Over (TEAO)\u003c\/strong\u003e on a \u003cstrong\u003e48Y frame\u003c\/strong\u003e about \u003cstrong\u003e5.6 inches\u003c\/strong\u003e in diameter, with a rated draw of \u003cstrong\u003e2.8 amps\u003c\/strong\u003e and an output of \u003cstrong\u003e0.56 kW\u003c\/strong\u003e.

The shaft is \u003cstrong\u003e1\/2 inch\u003c\/strong\u003e in diameter, flatted, with a \u003cstrong\u003e6 inch\u003c\/strong\u003e extension for the fan hub, and the overall motor length is \u003cstrong\u003e12.17 inches\u003c\/strong\u003e. Mounting is by \u003cstrong\u003eextended studs\u003c\/strong\u003e on the lead end, \u003cstrong\u003emounting holes in the shell\u003c\/strong\u003e or a \u003cstrong\u003ebelly band\u003c\/strong\u003e (band not included). Rotation is \u003cstrong\u003ereversible\u003c\/strong\u003e, the \u003cstrong\u003eservice factor\u003c\/strong\u003e is \u003cstrong\u003e1.0\u003c\/strong\u003e, and the motor can be mounted in any orientation. It is designed to run with a \u003cstrong\u003e15 MFD, 370 VAC\u003c\/strong\u003e run capacitor, which is not supplied with the motor.\u003c\/p\u003e\n\n\u003cp\u003eMatching horsepower and speed is not enough to call a condenser fan motor interchangeable. Check the \u003cstrong\u003e460V\u003c\/strong\u003e rating, the \u003cstrong\u003e48Y\u003c\/strong\u003e frame, the \u003cstrong\u003e1\/2 inch\u003c\/strong\u003e shaft diameter and length, the rotation direction and the wiring against the original nameplate and connection diagram. The nearby numbers are different motors: \u003cstrong\u003eEM3738F\u003c\/strong\u003e (1\/2 HP), \u003cstrong\u003eEM3737F\u003c\/strong\u003e (1\/3 HP) and \u003cstrong\u003eEM3736F\u003c\/strong\u003e (1\/4 HP) are lighter 460V models, while \u003cstrong\u003eEM3731F\u003c\/strong\u003e is the 3\/4 HP version for \u003cstrong\u003e208-230V\u003c\/strong\u003e. The Genteq catalog number \u003cstrong\u003e3739\u003c\/strong\u003e is also 3\/4 HP, 460V and 1075 RPM, but it is a separate motor with a longer body and a lower \u003cstrong\u003e2.03 amp\u003c\/strong\u003e rating, so compare shaft length and fit before swapping one for the other.\u003c\/p\u003e\n\n\u003cp\u003eA failing condenser fan motor usually shows up as a unit that hums with the blade slow or not turning, then trips on high head pressure or the compressor's own overload. Before condemning the motor, test the run capacitor against its \u003cstrong\u003e15 MFD\u003c\/strong\u003e rating, confirm the contactor is pulling in and the full \u003cstrong\u003e460V\u003c\/strong\u003e is reaching the leads, spin the shaft by hand to feel for bearing drag, and check the windings for continuity with no leakage to the shell. Because the thermal protector resets on its own, a motor that runs for a while, shuts off and later starts again is often overheating from a weak capacitor, a worn bearing or a plugged condenser coil rather than a random fault. Lock out the power and discharge the capacitor before touching any leads, and fit a rain shield or drip loop if the shaft will point upward.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCorrect Voltage Match:\u003c\/strong\u003e Built for \u003cstrong\u003e460V\u003c\/strong\u003e single-phase condenser circuits, so it suits units whose nameplate calls for \u003cstrong\u003e460V\u003c\/strong\u003e instead of the \u003cstrong\u003e208-230V\u003c\/strong\u003e models such as \u003cstrong\u003eEM3731F\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBuilt for Outdoor Duty:\u003c\/strong\u003e A \u003cstrong\u003eTEAO\u003c\/strong\u003e rolled steel shell, double \u003cstrong\u003eball bearings\u003c\/strong\u003e and \u003cstrong\u003eClass F\u003c\/strong\u003e insulation rated to \u003cstrong\u003e70°C\u003c\/strong\u003e ambient stand up to the heat and weather at the condenser.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSelf-Resetting Protection:\u003c\/strong\u003e \u003cstrong\u003eAutomatic thermal protection\u003c\/strong\u003e shuts the motor down before the winding is damaged and resets after it cools.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFlexible Mounting and Rotation:\u003c\/strong\u003e \u003cstrong\u003eExtended studs\u003c\/strong\u003e, shell mounting holes and \u003cstrong\u003ebelly band\u003c\/strong\u003e mounting, with \u003cstrong\u003ereversible\u003c\/strong\u003e rotation so the fan can turn clockwise or counterclockwise as the unit requires.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWhat run capacitor does the EM3739F use?\u003c\/strong\u003e A \u003cstrong\u003e15 MFD, 370 VAC\u003c\/strong\u003e \u003cstrong\u003erun capacitor\u003c\/strong\u003e, sold separately.
