### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect so far
  

*by J***. on Reviewed in the United States on October 11, 2024*

Worked perfectly to replace the start capacitor in an older 3 HP Craftsman air compressor. Please note that newer capacitors tend to be physically smaller than the ones they are replacing due to improvements in materials. I had to make a spacer from scrap rubber I had lying around to ensure that the capacitor didn't vibrate around inside the compartment on the motor. It's only been in one day so I can't speak to longevity, but so far so good!

    got my AC back up and running
  

*by V***1 on Reviewed in the United States on June 13, 2024*

My outside AC unit's fan stopped spinning up when it was running so I decided to just swap both the start and run capacitors, and that fixed it.  Both caps tested at the high end  of their rated capacity, so hopefully they last a good long time.  It's MUCH cheaper to swap these yourself rather than pay a tech over $100 to come out and do it for you.  Just make sure you shut off power at the outside box before opening up your outside unit.  This cap was the exact same dimensions as the one it replaced, so I didn't have to do any adjustments to the brackets that hold he caps.  The spade connections on the top for the wires were the same too, so it was very easy to swap.  The hardest part of the entire job was getting the cover back on the outside unit after I was done swapping the caps.
