Review: Reliable Spec Part—Returned After Fan Upgrade, Still Worth Considering for Legacy AC Systems - During a recent AC compressor overhaul, I purchased this 5µF capacitor as part of a proactive component refresh. I also installed a **dual-run capacitor** rated for both the compressor and fan circuits, anticipating the need for a separate fan capacitor alongside the new condenser fan motor. The 5µF unit arrived quickly, packaged securely with no terminal damage. The aluminum housing was solid, terminals spaced well, and the labeling was clear—ideal for quick identification during install prep. However, the fan motor I ended up installing had a **built-in capacitor**, which meant I didn’t need this standalone part. Instead, I wired the motor directly into the dual-run capacitor using the standard C, FAN, and HERM terminal layout. This worked flawlessly and simplified the system wiring. That’s the key takeaway for buyers: newer fan motors often include internal capacitors, so before sourcing a separate one, check your motor’s spec label or wiring diagram. If your system uses an older motor, this 5µF capacitor appears reliable and well-suited for run/start support. Even though it was returned unused, the build quality and delivery experience made a positive impression. If I were working on a legacy unit again—or troubleshooting a standalone fan circuit—this would be on my shortlist
Review: Tested out perfect. - I have been a ARIZONA registered master heat pump technician for over 25 years. The problem I have noticed with capacitors is that many of them are defective out of the box. The reason I say that is I test the microfarads while the capacitor is under load which will tell me it’s exact microfarad rating. 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 =35µF This 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 capacitors I 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.
