York S1-024-39520-000 Condenser Motor

The York S1-024-39520-000 is the OEM 1/2 HP, 230 V, single-phase programmable ECM condenser fan motor for select York air conditioner and heat pump outdoor units, supplied through York's Source 1 parts line. It is an electronically commutated motor (ECM) — a brushless DC design run by an internal microprocessor-controlled module instead of a fixed-speed induction winding — and it is built as a direct OEM replacement for residential and light commercial York systems. In the field this is the motor that spins the condenser fan, pulling outdoor air across the condenser coil so the compressor can reject heat and hold head pressure in a normal range.

Because this is a programmable ECM, its speed and torque behavior comes from onboard electronics matched to the equipment, which is why it is not a part to substitute by horsepower alone. A generic 1/2 HP, 230 V motor will not necessarily behave the way this one does, and a neighboring S1-024 motor number can differ in programming, mounting or shaft. Compare the part number on the motor nameplate and the model number of the outdoor unit against S1-024-39520-000 before ordering. Compared with a standard permanent split capacitor (PSC) motor, an ECM generally runs cooler, uses less electricity and runs quieter, and it does not depend on a conventional run capacitor the way a PSC condenser motor does.

A failing condenser fan motor usually announces itself with an outdoor fan that is not turning while the compressor runs, high-pressure lockouts or compressor overload trips, a hot or burnt smell at the motor, bearing noise such as grinding or squealing, or a fan that starts and stops erratically. Before condemning the motor, confirm 230 V at the line leads, confirm the control board is actually calling for the fan, and inspect the wiring harness plugs for heat damage — a bad board or a loose connector can look exactly like a bad motor. With power off, spin the fan propeller by hand: a stiff or gritty shaft points to the motor, while a wobbling or cracked blade points to the fan itself. Always open and lock out the disconnect and let the motor electronics discharge before unplugging the harness, and check the fan guard and propeller while the motor is out.

Key Benefits

• Direct OEM Replacement: Built for select York condenser units, so the 1/2 HP, 230 V rating and the programmable ECM electronics match what the equipment was designed to use.
• ECM Efficiency: Brushless DC operation means lower energy use, less heat in the windings and quieter operation than a comparable PSC motor.
• Protects the Compressor: Steady condenser airflow keeps head pressure and discharge temperature under control, which is what protects the compressor on hot days.
• Source 1 Part Number: Ordering by S1-024-39520-000 keeps you on the exact York number instead of guessing between look-alike motors.

Common Questions

• What does this motor do? It drives the condenser fan on a York air conditioner or heat pump outdoor unit, moving air across the outdoor coil.
• What are its electrical ratings? It is a 1/2 HP, 230 V, single-phase ECM condenser fan motor with programmable electronics.
• Will any 1/2 HP 230 V motor work instead? Not safely to assume — an ECM carries its control behavior in its electronics, so match the S1-024-39520-000 number and your unit's model number rather than horsepower and voltage alone.
