description

The Service First SFMB253SP1V is a direct-drive HVAC blower motor designed for residential and light-commercial furnace and air-handler applications. It is rated at 1/4 HP, 115 volts, 1075 RPM, and 3 speeds. Trane's Service First motor literature identifies it as a 48-frame, open-air-over (OAO), sleeve-bearing motor.

This motor is designed as a practical replacement for compatible PSC direct-drive blower applications where the horsepower, voltage, RPM, rotation, capacitor, shaft, and mounting requirements match.

🛠️ HVAC Depot Pro Tip

When replacing a furnace blower motor with the SFMB253SP1V, don't match by horsepower alone.

Confirm:

1/4 HP + 115V + 1075 RPM + 3-Speed + 48 Frame

Also verify the shaft diameter and length, rotation, mounting arrangement, full-load amperage, and required capacitor MFD against the original motor.

This is especially important with blower motors because two 1/4 HP, 1075 RPM motors may still have different shaft, capacitor, amperage, or mounting requirements.

Cross-Reference & Replacement Information

Service First Part Number:
SFMB253SP1V

Distributor Stock Reference:
175189

A Nidec replacement cross-reference also identifies SFMB253SP1V as a direct interchange candidate for certain replacement applications. .

Equipment Compatibility

The SFMB253SP1V is intended for direct-drive blower applications requiring its electrical and mechanical specifications.

Typical applications include:

  • Gas furnaces

  • Electric furnaces

  • Air handlers

  • Residential split systems

  • Heat-pump air handlers

  • Direct-drive squirrel-cage blower assemblies

Compatibility should be determined from the original motor specifications or complete equipment model and serial number rather than the equipment brand alone.
