York S1-024-20043-700 Run Capacitor

The York S1-024-20043-700 Run Capacitor is a critical OEM component designed for high-reliability circuit stabilization in residential and light commercial HVAC systems. This 5 Microfarad 370Vac Oval Run Capacitor serves as the direct technical replacement for the legacy part number 024-20043-000. When diagnosing a motor that fails to reach full RPM or hums without starting, verifying the capacitance of the fan motor run capacitor is the standard protocol. Utilizing an OEM York replacement part ensures that the motor operates within its designed torque curve and temperature rise limits, preventing premature winding failure. This unit features a non-PCB oil-filled construction with an internal pressure sensitive interrupter for safety. It is engineered to maintain a stable phase shift, specifically for condensing fan motors and small blower applications where a specific 5 MFD 370V capacitor rating is required by the manufacturer’s data plate to ensure peak electrical efficiency.

Key Benefits for Contractors

• Direct OEM Fit: Drop-in replacement for 024-20043-000, ensuring no modifications to the mounting bracket are necessary.
• Precision Tolerance: Maintains the specific 5 microfarad rating required to keep motor amperage within nameplate specifications.
• Robust Construction: Housed in a standard oval run capacitor metal casing for superior heat dissipation compared to generic alternatives.
• System Compatibility: Validated for use across York, Luxaire, and Coleman equipment requiring a secondary 370VAC phase shift.

Common Installation Questions

Can I use a 440V capacitor to replace this 370V unit?
Yes, a capacitor with a higher voltage rating can safely replace a lower voltage unit like the S1-024-20043-700, provided the capacitance (5 MFD) remains identical. However, you cannot go lower than 370V.

What are the signs that this 5 MFD capacitor has failed?
Common indicators include a bulged top casing, oil leaks, or a capacitance reading outside of the +/- 5% or 10% tolerance range when testing with a multimeter.

Is this capacitor compatible with brands other than York?
While this is a York S1-024-20043-700 OEM part, it can be used in any application calling for a 5 MFD 370Vac oval capacitor, provided the physical dimensions fit the housing.
