Armstrong Furnace R107025-01 Motor

The Armstrong Furnace R107025-01 Motor is a genuine OEM condenser fan motor engineered for Armstrong Air and Lennox family HVAC systems. This shfated-down condenser motor operates at 1/5 HP and 1075 RPM, utilizing a 208-230V, single-phase power supply. Professional technicians use the R107025-01 as a direct replacement for 42521-001 and R42521-001, ensuring the electrical specifications and physical mounting align with factory requirements for outdoor condensing units. Designed to handle the high static pressure of residential cooling systems, this permanent split capacitor (PSC) motor maintains the critical airflow necessary for heat rejection and compressor protection.

• Universal Fitment: Serves as the precise replacement for 42521-001, eliminating the need for mounting bracket modifications in the field.
• Optimized Heat Dissipation: Built to withstand commercial-grade duty cycles, preventing premature thermal overload trips during peak ambient temperatures.
• High Efficiency Performance: The 1075 RPM rating is calibrated to match original fan blade pitches, maintaining the AHRI-rated efficiency of the condensing unit.
• Quiet Operation: Precision-balanced internal components reduce bearing wear and operational noise, a common requirement for high-density residential installs.

Is this a multi-speed motor?
No, this is a single-speed 1075 RPM motor designed specifically for condenser fan applications where constant RPM is required for consistent head pressure.

What capacitor does the R107025-01 require?
You should verify the microfarad (MFD) rating on the new motor nameplate, as Armstrong Air replacement motors may require a specific run capacitor (typically 5 MFD/370V) that may differ from the failed unit.

Can I use this for a furnace blower?
This motor is an outdoor condenser fan motor; it is not designed for the high-torque requirements of indoor blower wheels.
