Your cart is empty. A capacitor is an electric component that temporarily stores an electrical charge. A dual "run capacitor" supports two electric motors, such as a fan motor and a compressor. Round dual run capacitors are used to start and run the unit more efficient. It saves space by combining two physical capacitors into one case. The dual capacitor has three terminals labeled "C", "FAN", and "HERM", which stand for the *C*ommon, Fan, and *HERM*etically sealed compressor.
Dual capacitors come in a variety of sizes, depending on the capacitance (µF = MFD = micro farad), such as 60 plus 5 µF, and also the voltage. A 440 volt capacitor can be used in place of a 370 volt, as it is build better, but the 370 can’t be used in place of a 440 volt. It will work for a while and will fail prematurely, as exceeding the capacitor's rated voltage will cause the dielectric to break down and the capacitor to short out. Same as an electric wire- 600V rated wire is better than 300V one .The capacitance(µF or MFD or micro farad) must be the same or stay within 10%+ or 5%- of its original value . Example: 35 µF cap can be substituted by 33 - 38 MFD with the same or better voltage ratings capacitor.
If your fan is working but compressor not, or the capacitor is bulged on top most likely your capacitor is defective. Round capacitor can be used to substitute oval shape one with the same MFD AND Volt specs.
You will ask “Why I need a Cap that is rated 440V in my A/C?”
Answer: You need to realize that a motor is an inductive device. When the supply voltage is applied to the motor run winding, the voltage across the start winding will be increased to a higher voltage value. A motor acts like a transformer with the run winding acting as the primary and the start winding acting as the secondary. This is why the capacitor has a much higher voltage rating than the 230 being the supply voltage.
If a Capacitor is not EIA-456-A approved means it is NOT approved for USA market.

I used the part to repair a central air conditioning unit. the compressor and fan needed the capacitor replaced and everything is working now.

I bought this when my fan stopped working in my backyard AC unit. Took a guess and replaced the capacitor with this one from Amazon and it started right up and is working fine. Don’t panic when this one is a little bit longer than the old one you replaced. It works fine. Saved a $200 repair bill from an Heating and Air guy and a novice can replace one of these.

Our A/C stop getting cold, and we went outside to look at the unit and noticed the fan wasn't turning on. It was just humming. I took a screwdriver and made sure the fan blades would spin so the motor wasn't seized up. Doing some research i found that this was probably the issue. Cheap fix and we are back up and going!!

Just the capacitor I needed for the job at the right price.

Replace the old 35-5 capacitor (pictured) with a new part from Amazon. It fixed my starting problems with my 12 year air conditioning unit. I cannot comment on the longevity of the part as it was just installed.

Our AC went out…in Texas…in summer and my father in law identified that it was this part (the old one) that wasn’t working. I ordered it and it was here in 1.5 days and he replaced it and it’s been working perfectly since!

Had my first issue with my smaller HVAC since the house was built. I have experience after dealing with issues with my larger unit so I had a feeling the capacitor just needed to be replaced. The last one was this brand and it lasted about 13 years so I felt confident in buying this brand again for the replacement. Hoping it lasts long, too.I will NEVER get over the prices HVAC companies charge to replace these (average) $15-20 parts. Do a little research, if it sounds like this part needs to be replaced and it's been enough years, it's an easy DIY fix. It will cost you little to just try without even using a multimeter to confirm it, and that's if it doesn't already look physically blown.

You could pay someone $250+ to install this $14.50 capacitor, or you can just put it in yourself for free. I've never replaced one of these, but indications were the capacitor was bad on my A/C, so I figured if someone could put one in there the first time, then all I had to do is put another one in, so I did. It is so easy to do that it makes no sense why they are so expensive to replace.I would usually remove the old part, but it is uniquely situated in a bolted frame (top left new one), so I just unhooked the wires and attached them to this capacitor and jammed it up under the wiring and put a strap on it (marked 2023). I left the old capacitor in its place, because they was no real need to remove it. While I was at it, The old one was marked 2020, but that doesn't mean too much, although this one is guaranteed for 5 years. I cleaned the coils with Super Clean and rinsed with the garden hose full-blast from the inside while I was working on it. I'm shocked how dirty they get just from grass clippings, so I now turn the unit off when mowing the grass. Trust me, it makes a huge difference and could save your unit. That may have taxed the old capacitor, I couldn't say, but you couldn't see through the coils before, but you can now. It has to be working more efficiently now.I could have removed the old one and positioned this one the same way, but I was doing it alone and the weather was against me so I did what any redneck would do under the circumstances. It has no bearing on its function so until it needs another one, I'm leaving it like that. I may buy another one soon just to have on hand in case the A/C goes out. My unit is in full sun and that can take half the life out of a capacitor. My previous one went bad in only 3 years because of it. After cleaning the coils, this job would have cost any homeowner $500. I'm amazed at how easy this job was and am very pleased with the capacitor and highly recommend it.

My old 97 Keep-rite A/C unit was dead. Researched the potential cause and replaced the cheapest part, the old capacitor, pictured, with the new Power Well. Approx 1-2 hours including clean up. Starts and runs well.Please review the instructions from, *The do it yourself HVAC guy on YouTube.*

Followed YouTube instructions. Same specs as the original, turned the breakers off !!! DRAIN the CAPACITOR by shorting it with a screw driver or you can get a ZAP. Take a picture of the colored wires and where they go and replaced them on the same location on the new one.
