35/3 MFD Round Run Capacitor (370V) Works great!
35/3 MFD Round Run Capacitor (370V) Not only works great, but you cannot beat the price. It fit perfectly in a Rheem AC unit that has worked perfectly every since. I also bought the single pole terminal from SupplyHouse.com and installed both at the same time. Everything works great and I have no complaints.

Just what I needed and fast shipping.
Actually bought this exact capacitor about six years ago to fix my a/c unit myself. Still working just fine, came here to buy another to keep on hand since Murphy's law dictates when/if my a/c goes out again it will be during a horrible heat wave like last time. Fast shipping, buy with confidence!

Verified Reply- Supplyhouse StaffYes, they are both dual capacitors, its probably listed as a run since the unit also has a start capacitor.
