York S1-024-31993-000 Capacitor

The York S1-024-31993-000 Capacitor is a task-specific start component engineered to deliver the high-torque surge required for HVAC compressor startup. This 145-174 MFD start capacitor is rated for 330V and is specifically designed for single-phase AC systems and heat pumps, including the York YCE series microchannel units. As a veteran technician knows, starting torque is critical when a compressor must overcome high head pressures; this OEM York start capacitor provides that essential peak current before drop-out during the run cycle.

Encased in a rugged black plastic phenolic housing, this unit serves as a vital hard start assistant for YORK air conditioning parts. It replaces failed capacitors that manifest as compressor humming or frequent tripped breakers. For service contractors, ensuring capacitor compatibility with the S1-024-31993-000 part number ensures your refrigeration and heating equipment maintains efficient duty cycles without unnecessary stress on the motor windings.

• High Torque Delivery: Provides a massive 145-174 microfarad boost to overcome Locked Rotor Amps (LRA) and initiate compressor rotation instantly.
• Universal Compatibility: Direct OEM replacement for York S1-024-31993-000, suitable for condensing units and heat pumps including models AC5B024F1C and ACP036C1021.
• Voltage Stability: Rated for 330VAC operation, ensuring reliability across residential and commercial HVAC setups.
• Durable Insulation: The phenolic resin shell offers superior electrical insulation and heat resistance compared to generic poly-film alternatives.

What are the signs that a York start capacitor is failing?
Standard signs include the condenser fan running but the compressor not starting, a distinct audible hum upon startup, or the unit being physically swollen or leaking electrolyte.

Can I replace a 330V start capacitor with a lower voltage rating?
No. In HVAC motor circuits, you must match or exceed the original voltage rating. Using a lower-rated capacitor will lead to immediate dielectric breakdown and potential failure of the starting relay.

How do I accurately test a 145-174 MFD capacitor?
After safely discharging the capacitor, use a digital multimeter set to the capacitance (µF) range. The reading must fall within the 145-174 MFD spread; any reading significantly lower indicates internal degradation.
