This is done by checking the amps and volts wile it is running. I use what I call the 2652 method.The simple formula is Start Winding Amps X 2,652 ÷ Capacitor Voltage = Microfarads.Sample: 5 amps Times 2652 divided 369 volts =35µFThis is the correct way to test a capacitor. There are meters that have capacitor testers settings on them but I never used them because they are pretty much useless unless you just wanna know what size it is. You need to put a capacitor under load to make sure it doesn’t have any leaking Through that dielectric.This capacitor I have bought several times and it is exact to what it is rated at.Some brands of air conditioners you will find bad capacors on every one of them when you fire them up new. I don’t wanna mention any names but one that does this the most makes air conditioners that start with the letter C and another brand with the letter B. They actually buy rejected capacitors for their units to get them cheaper so sad.It’s very important to have a correctly size capacitor to create a third leg properly. This is basically making a third phase. If you’re capacitor is leaking electricity through the dielectric it will shorten the life of your unit. About 25% of brand new air conditioner run capacitors do not pass the test.They can only be as far as 10% off of what they’re rated at is there any greater than that it’s best to throw them away. It’s also a good thing to change your air conditioning run capacitor at least every four years. In hotter states possibly more often.They make a 370 V and the 440 V capacitorsI highly recommend going with the 440 V rating it will put up with more heat and will last longer.The 440 V rating only means how much electricity it can handle. So it’s basically heavier duty than the 380V ones. Your air conditioner might be 220 V but when the compressor is running the voltage across the run cap can double that. So be warned if you’re going to test a live Ron cab you’re going to have to be extremely careful because the voltage coming off that run cap can kill you.With that being said I recommend this brand. ### ⭐⭐⭐⭐⭐ Working Perfectly at the moment!
