Replaces / Cross-Reference Part Numbers

Replaces any round start capacitor with a matching capacitance range (124-149 µF) and voltage rating (220-250 VAC). It is a universal replacement part compatible with various brands and models that meet these specifications.

Compatibility & Fitment

For use in single-phase AC motor starting circuits. Applications include:

• HVAC compressors and fan motors
• Air compressors
• Well pumps and pool pumps
• Refrigeration units
• Other electric motors requiring a starting torque boost

When to Replace

A failing capacitor can prevent a motor from starting correctly. Replace the capacitor if you notice:

• The motor hums but does not start or turn
• The motor starts slowly or with difficulty
• The circuit breaker trips upon motor startup
• Visible damage to the capacitor, such as bulging, cracking, or leaking oil

Installation Tips

• Disconnect all electrical power to the equipment before beginning service.
• Safely discharge the old capacitor by shorting its terminals with an insulated tool.
• Confirm the µF (MFD) and VAC ratings of the replacement part match the original specifications.
• Note the placement of wires on the old capacitor terminals before disconnecting.
• Ensure all wire connections are secure on the new capacitor.
