Replaces / Cross-Reference Part Numbers

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

  • Capacitance: 30/7.5 uF or 30+7.5 MFD
  • Voltage: 370V or 440V (this 370/440V unit can replace either)
  • Shape: Round (ensure physical dimensions allow for a secure fit)

Compatibility & Fitment

Designed for use in HVAC systems, including central air conditioners and heat pumps. This dual capacitor provides power to two electric motors simultaneously:

  • A higher capacitance terminal (30 uF) for the compressor motor (HERM).
  • A lower capacitance terminal (7.5 uF) for the condenser fan motor (FAN).

When to Replace

A capacitor may need replacement if you observe these symptoms:

  • Outdoor unit hums but the fan does not spin.
  • Compressor fails to start or struggles to turn on.
  • AC unit starts but then shuts down shortly after.
  • Visible signs of damage, such as a bulging or leaking top.
  • Capacitance measures outside the ¬±5% tolerance when tested with a multimeter.

Installation Tips

  • WARNING: Disconnect all electrical power to the HVAC unit before handling the capacitor.
  • Safely discharge the old capacitor by carefully shorting across the terminals with an insulated-handle screwdriver.
  • Document or photograph the wire connections to the C, FAN, and HERM terminals before removal.
  • Connect the wires to the corresponding terminals on the new capacitor.
  • Secure the new capacitor in the mounting bracket to prevent vibration.

Great replacement kit
Called around for quotes to get them replaced and everyone was quoting over $2k just for bellows. Figured I’d give it a try. The rubber is good quality and feels soft. Time will tell but this is an easy job if you’re mechanically inclined. Make sure you replace the plastic water pickup fitting while you’re at it. Found mine to be cracked on disassembly and had to wait for a new one. Should be a easy 3-4 hour job if your not doing the bearing and only doing bellows

Good value, very useful for go kart wiring
Size: 100ft, Style: 6C-18AWG
It's a good spool to have around to wire lights and things on the go karts. Also came in handy when I had to patch a bit of melted wire harness on the tail of the old Dodge.
