Replaces / Cross-Reference Part Numbers
- Replaces any single-value round capacitor with matching 45 uF capacitance and either a 370V or 440V rating.
- Universal replacement for capacitors used by brands such as Carrier, Goodman, Lennox, Rheem, Trane, York, and others.
Compatibility & Fitment
- For continuous duty in single-phase motor applications.
- Commonly used in air conditioner condenser units, heat pumps, and furnace blower motors.
- Also used for compressor motors, fan motors, and refrigeration systems.
When to Replace
- Motor hums but fails to start.
- Fan requires a manual push to begin rotating.
- AC compressor does not engage.
- Visible damage to the existing capacitor, such as a bulging or swollen case, or leaking fluid.
- Capacitance measures outside the specified tolerance when tested with a multimeter.
Installation Tips
- Disconnect all electrical power to the unit before servicing.
- Discharge the old capacitor by carefully shorting the terminals with an insulated-handle screwdriver or a discharge tool.
- Confirm the new capacitor's uF rating matches the original part.
- The voltage rating of the new capacitor must be equal to or higher than the original. A 440V capacitor can safely replace a 370V capacitor.
- Note the wire positions on the original terminals before disconnecting.
- Secure the new capacitor using the existing mounting bracket.
