Replaces / Cross-Reference Part Numbers

This capacitor replaces any round dual run capacitor with matching specifications. Verify the following on your original part:

• Capacitance: 45/5 uF, 45+5 MFD
• Voltage: 370V or 440V (a 440V rated capacitor can replace a 370V unit)
• Shape: Round
• Physical dimensions for proper mounting

Compatibility & Fitment

• Application: Dual run capacitors combine two capacitors into one unit to start and run a compressor motor and a fan motor simultaneously.
• Designed for use in HVAC systems, including air conditioner (AC) condensing units, heat pumps, air handlers, and furnace motors.
• Compatible with units from major brands that require a capacitor with matching electrical specifications.

When to Replace

A failing capacitor can cause motor damage. Consider replacement if you observe the following symptoms:

• The outdoor unit hums but the fan does not spin.
• The compressor does not start.
• The AC unit does not blow cold air.
• The capacitor casing is visibly swollen, bulging, or leaking oil.
• The system starts slowly or requires multiple attempts to start.

Installation Tips

• Disconnect all electrical power to the HVAC unit at the breaker box and service panel before beginning work.
• Safely discharge the old capacitor by shorting the terminals with an insulated screwdriver.
• Note the wire placement on the C, FAN, and HERM terminals before disconnecting the old unit.
• Connect the wires to the corresponding terminals on the new capacitor.
• Ensure the new capacitor is secured with the original mounting bracket.
• Consult a qualified technician if you are not comfortable performing this repair.
