Replaces / Cross-Reference Part Numbers

  • USA2222A
  • Jard 12954
  • P291-7074R
  • C37075R
  • C47075R
  • PRCFD707.5A
  • Replaces any round dual run capacitor with matching 70/7.5 MFD and 370V or 440V specifications.

Compatibility & Fitment

  • Designed for HVAC applications including air conditioners, heat pumps, and condenser units.
  • Functions as a direct replacement for capacitors with identical capacitance (MFD) and voltage ratings.
  • A 440V rated capacitor can safely replace a 370V capacitor; do not replace a 440V capacitor with a 370V unit.
  • Verify physical dimensions (diameter and height) to ensure proper fit in the mounting bracket.

When to Replace

  • AC unit or fan motor will not start or is slow to start.
  • A humming noise comes from the unit during attempted startup.
  • The capacitor case is visibly swollen, bulging, or leaking oil.
  • The compressor starts, but the condenser fan does not spin.

Installation Tips

  • Disconnect all electrical power to the HVAC unit before beginning work.
  • Carefully discharge the old capacitor by shorting the terminals with an insulated screwdriver.
  • Note or photograph the wire placement on the C (Common), FAN, and HERM (Hermetic) terminals before disconnecting.
  • Connect wires to the corresponding terminals on the new capacitor.
  • Securely mount the new capacitor in the unit's bracket.
  • Professional installation is recommended if you are not familiar with HVAC electrical systems.

FAQs

Common symptoms of a failing capacitor include the air conditioner or heat pump failing to start, a humming sound coming from the condenser unit, or the fan motor struggling to reach full speed. If the top of the capacitor appears domed or bulging, or if there is any sign of leaking oil, it has failed and must be replaced.
Yes. A 440V rated capacitor is a direct, high-quality replacement for a 370V unit. It is designed to handle higher voltage thresholds, which often results in a longer service life in HVAC applications.
Installation typically takes 15–30 minutes. You will need a screwdriver to remove the service panel and a pair of needle-nose pliers. Always turn off the power to the HVAC unit at the disconnect box before beginning. Discharge the old capacitor using an insulated screwdriver across the terminals before disconnecting the wires. Ensure you transfer the wires to the corresponding terminals (Herm, Fan, and Common) exactly as they were on the original unit.
This round dual run capacitor measures 2.5 inches in diameter and 4.33 inches in height. Please ensure you have sufficient clearance in your condenser's electrical compartment before installation.
The 70 MFD (microfarad) rating is for the compressor motor, while the 7.5 MFD rating is for the condenser fan motor. This dual-run design allows a single capacitor to manage both motors simultaneously, which is standard for most residential air conditioning and heat pump systems.
Yes. Capacitors store a significant electrical charge even after the power is turned off. Before touching the terminals, you must discharge the capacitor by placing an insulated-handle screwdriver across the terminals to create a short circuit. Do not touch the metal blades of the screwdriver or the capacitor terminals during this process.
