This item was used on the squirrel cage fan in my AC unit. Sam 20uF cap. works great! I have no complaints. this item appears to be of good quality with no noticeable discrepancies. very easy to install. I hope the lifespan is good. I will update if it goes out. otherwise it's still working for me. Its a good price, good product. I'd recommend this.

The capacitor looks to be a good build quality but can't speak for longevity yet. I replaced my capacitor on my 60 gallon air compressor motor, now it works as it should.

I used this BlueStars 20 uF capacitor to replace the old one in my Grundfos SA-SPM6 control box, which is connected to a 2HP well pump. The issue was that the pump would randomly stop after running for a while, especially when filling the pond. After installing this capacitor, the problem was completely resolved—the pump has been running flawlessly ever since and hasn’t missed a beat. The capacitor feels well-made, and installation was straightforward. It’s been holding up great under regular use. For the price, it’s an excellent value, especially considering the peace of mind it’s brought by getting the system back to working like it should. Highly recommend if you're troubleshooting a similar issue!
