With a robust operating range and compliance with rigorous safety standards, this capacitor ensures optimal functionality and longevity, making it an essential choice for HVAC professionals and DIY enthusiasts alike. ## Description A capacitor is an electric component that temporarily stores an electrical charge. A "run capacitor" supports electric motors, such as in air conditioner or heat pump units, a fan motor and a compressor motor. The capacitor has two terminals. Capacitors come in a variety of sizes, depending on the capacitance (µF or MFD), such as 40 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) must be the same or stay within 10%+ or 5%- of its original value . Example: 50 µF cap can be substituted by 47.5 to 55 µF with the same or better voltage ratings capacitor . Round oval-shaped run capacitors are commonly used for air conditioning, to help in the starting of the compressor and the condenser fan motor. ## Features - Durable Grade Premium 20 MFD Capacitor for AC Compatible with most Carrier AC Capacitor - Meets or Exceeds OEM Specifications Quality.

I thought that he could have possibly created a power surge that resulted in our capacitor blowing out and before we paid the $100 to have our home warranty company send an AC repairman out to diagnose and fix the issue, I took a chance on replacing the capacitor myself. We checked Lowe's, Home Depot, and a couple other local hardware stores and no one carried the capacitor type we needed. This one was basically identical, except ours was 3% and this one is 5%.Delivery was fast, and I had no trouble switching out the capacitors. I was so pleased when such a simple solution fixed our AC, and our fan is working again. Definitely try this product before you call a professional!!! ### ⭐⭐⭐⭐⭐ just the right item needed *by B***P on July 22, 2023* Ordered this item to have as a stand by , very good for meney, fast shipping . Will reodered if needed again. I tested it with a voltage meter it was good so I have part to change out when needed, go on utube see how to test the one that went out and test new to make sure its good. This will save you big money, DIY for sure ### ⭐⭐⭐⭐⭐ fixed it with ease *by N***N on March 9, 2023* A/C outside unit hummmed then kicked off. "thought it might be the capasitor so checked the size ordered it. Within a week it arrived. Replaced it and now we have upstairs air conditioning fit perfectly ## Frequently Bought Together - The HVAC Genius 20 MFD AC Capacitor, 20uF ±5% 370VAC/440 Volt Round Run Start Capacitor for Air Conditioner Condenser Straight Cool or AC Motor and Fan Starting or Heat Pump Air Conditioner - The HVAC Genius 15 MFD AC Capacitor, 15uF ±5% 370VAC/440 Volt Oval Run Start Capacitor for Air Conditioner Condenser Straight Cool or AC Motor and Fan Starting or Heat Pump Air Conditioner - The HVAC Genius 10 MFD AC Capacitor, 10uF ±5% 370VAC/440 Volt Oval Run Start Capacitor for Air Conditioner Condenser Straight Cool or AC Motor and Fan Starting or Heat Pump Air Conditioner --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/530488596-20-mfd-ac-capacitor-20uf-5-370vac-440-volt-round](https://www.desertcart.it/products/530488596-20-mfd-ac-capacitor-20uf-5-370vac-440-volt-round) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-09*
