🛠️ HVAC Depot Pro Tip

The 51-23017-42 is a multi-horsepower PSC blower motor, so the installation and wiring configuration must match the required blower application.

Before replacing the motor, verify:

  • Required horsepower

  • 120V power supply

  • 1075 RPM requirement

  • Required blower speed

  • Rotation

  • Shaft diameter and length

  • Mounting configuration

  • Run capacitor requirement

Depending on the horsepower configuration, published specifications list 10, 12.5, or 15 MFD at 370V capacitor requirements. Always use the capacitor specified for the actual motor configuration/nameplate rather than selecting one based solely on the part number.

Equipment / Model Compatibility

The 51-23017-42 is designed for compatible:

  • Rheem furnaces

  • Rheem air handlers

  • Ruud furnaces

  • Ruud air handlers

  • WeatherKing HVAC equipment

  • Compatible residential furnace blower assemblies

  • Compatible air-handler blower assemblies

Verify the complete HVAC equipment model number before ordering.
