Replaces / Cross-Reference Part Numbers

  • This is a universal replacement for round dual run capacitors with matching specifications.
  • Replaces any capacitor with a 45/7.5 MFD rating and a voltage of 370V or 440V.
  • Can be used to replace a 370V rated capacitor, as 440V is a higher voltage rating. Do not use a 370V to replace a 440V capacitor.

Compatibility & Fitment

  • Designed for heavy-duty, continuous use in HVAC systems.
  • Powers both a compressor motor (45 MFD) and a fan motor (7.5 MFD) simultaneously.
  • Commonly used in residential and commercial air conditioner (AC) condensing units and heat pumps.
  • Verify physical dimensions to ensure proper fit within the unit's mounting bracket and available space.

When to Replace

  • Outdoor unit produces a humming sound, but the compressor or fan fails to start.
  • Fan blades do not spin without a manual push-start.
  • AC system blows warm air or fails to cool.
  • Visible signs of failure on the existing capacitor, such as a swollen or bulging top, rust, or fluid leakage.
  • Frequent tripping of the circuit breaker when the AC unit attempts to start.

Installation Tips

  • Disconnect all electrical power to the HVAC unit before servicing.
  • Safely discharge the stored energy from the old capacitor by shorting the terminals with an insulated-handle tool.
  • Note or photograph the wire connections to the C, F, and HERM terminals before removing the old part.
  • Ensure the MFD and voltage ratings of the replacement part match the original specifications.
  • Secure the new capacitor firmly in the mounting strap to prevent damage from vibration.

Great size for 5 year olds!
Color: Disney: Frozen Elsa's Snowflake, Style: Kids Medium
This is a darling backpack. My daughter has been using it for a few months already and it’s pretty sturdy. The size is excellent for 5 year olds. It took me a while to find a backpack small enough that would fit her lunch box.

It was officially time to transition from a diaper bag to a big girl backpack! And both my daughter and I love this backpack! It is perfect size for her and holds everything she needs for school. It’s perfect for everyday use. I think the price is fair for the quality and sturdiness! She is gonna be able to use this until kindergarten! I definitely recommend!

Good size toddler backpack! My son is obsessed with every character on the backpack. We got matching water bottle and lunch box too so everything is coordinated for daycare. Been using for 8 months now with no issues. Very durable. All zippers intact and work with ease.

Couldn't be better!
Size: Large
Yes, these are "old lady" boxers, but you can't beat the comfort and the fact that they are all cotton with covered elastic. I usually wear a 7 in Hanes, etc. Large (or ex lg if you want them looser) fit me fine. They looked small out of the package, and even smaller after washing, but still fit. Size up if you are unsure.
