Review: It is a bit bigger than the capacitor in my dehumidifier, but I was able to make it work with a few cuts to the dehumidifier’s plastic housing. It was a fairly easy replacement while following a couple YouTube videos and was my first time replacing a capacitor, so you can definitely figure it out too. The dehumidifier runs great now!

## Questions & Answers

**Q: This capacitor replaces the capacitor that i have defective arcotronics  50uf  (c.87.0ef3 mkp) ?**
A: I can't find the specs for your arcotronics capacitor.  Please look on your capacitor to see if you can find the voltage.  If is 370 or 450 volts (370/450V) then this capacitor should work for your application.  If the voltage is something else or missing then i'm afraid I can't answer your question.  Good luck!

**Q: Will this replace a cbb65 (rohs) 55uf =- 5% 450vac c 40/70/21 50/60 hz  from a kenmore 253.70251 window unit?**
A: I’m not an expert… I got this for a RV AC unit,
but all the specs match so, yes.

**Q: currently have a 45 uf +/- 6% 440 vac mars brand can i use this one as replacement even though its a  50uf rating ??**
A: No I would not do that ,try to stick to the original value. A lower value could make the motor run not optimal.

**Q: replacing 50uf +5 370vac 50/60hz 40/85/21 - is this unit compatible?**
A: Because the capacitance is 50uf, not 50+5uf, this unit is not compatible. Thanks!

*by D***N on 27 May 2025*

When my air conditioner suddenly stopped cooling, I thought I was in for an expensive service call. After some research, I realized the capacitor was likely the culprit, so I decided to replace it myself. This capacitor was a perfect match, easy to install, and got my AC unit running again in no time! Within minutes of installation, the unit powered back on, and my house was cool again. The quality feels solid, and it functions just as expected—no issues at all. The fact that I was able to solve the problem myself saved me hundreds of dollars in labor costs. If you're experiencing AC issues and suspect the capacitor, this replacement is a lifesaver. It’s reliable, affordable, and gets the job done. Definitely worth keeping one on hand for future maintenance!
