🛠️ HVAC Depot Pro Tip

Pay particular attention to the voltage suffix when replacing this motor:

SFMB753SP1V → 3/4 HP | 115V | 1075 RPM | 3-Speed

SFMB753SP2V → 3/4 HP | 208/230V | 1075 RPM | 3-Speed

Trane lists both motors with the same horsepower, RPM and speed count, but with different operating voltages.

Before installation, also verify the original motor's shaft dimensions, rotation, mounting arrangement, amperage, and capacitor MFD. Do not select a replacement based only on horsepower and RPM.
