Replaces / Cross-Reference Part Numbers
- Replaces any single run round capacitor with matching 65 MFD capacitance and 370V or 440V specifications.
- Verify physical dimensions for proper fit.
Compatibility & Fitment
- Used for single-phase motor start and run applications.
- Commonly found in AC units, heat pumps, compressors, and condenser fan motors.
- Compatible with systems requiring a 370 VAC or 440 VAC rated capacitor. A 440V capacitor can replace a 370V capacitor, but not vice-versa.
When to Replace
- Motor hums but fails to start or starts slowly.
- Fan blades do not spin or turn at a reduced speed.
- Compressor fails to start.
- Visible signs of damage such as swelling, bulging, or fluid leakage from the capacitor case.
- Capacitance measures outside the ±5% tolerance range when tested with a multimeter.
Installation Tips
- Disconnect all electrical power to the unit before performing service.
- Safely discharge the existing capacitor by shorting the terminals with an insulated-handle screwdriver.
- Note the wire placement on the old capacitor's terminals before disconnecting.
- Ensure the new capacitor's voltage and MFD ratings match the component being replaced.
- Professional installation is recommended if you are not familiar with electrical service procedures.
