Works well, sized to my original running cap
Out of the box, I measured capacitance to be 44.5uF which is well within the 5% tolerance (98.89% or 1.11% off depending on how you want to view it). I've replaced my existing with a few others and they've always been smaller so it would slip right through the capacitor holding bracket. Those I just left the cap sitting on the platform while it was still inside the bracket. This was sized to the original so I was actually able to use the holding bracket by loosing the screw, inserting this capacitor, then tightening the screw so the capacitor is only held by the bracket and is off the platform. Easily hooked up and fan came right on when I re-inserted the switch at the disconnect. I am hoping it will last the expected 5 years - will try to remember to update this post for when it fails.

Replace and save
AC went down, ice on the evaporator and lines. Replaced the capacitor with this one, as all the numbers matched up. AC now running perfect. Pull the disconnect outside, remove the cover on the condensor (corner cover, not the whole thing) take a pic of where the wires connect, install new capacitor, reinstall the power disconnect and enjoy your cold house, knowing you saved yourself about 400 bucks. Good time to clean the evaporator and condensor!

It’s easy to replace and less expensive to do it yourself.
Easy to replace. It was the same size as the original one. Everything was compatible and unit and fan came back on after replacing. Sorry didn’t get a picture or video.
