I was installing a slow starter fro my AC to increase longevity of the AC so I decided to go ahead and replace the dual capacitor with a better one. My AC is working much more efficiently and reliably now. This cap has a lead for the compressor and the fan motor. This isolates them from each other so if your fan isn't starting move the lead. Having the compressor isolated from the fan prevents a huge spike in the current draw and prevents a failure of one causing a failure of the other. ### ⭐⭐⭐⭐⭐ AmRad Dual Run Capacitor *by M***C on Reviewed in the United States on 11 December 2015* If your condenser fan quits running and or your compressor motor isnt starting more often than not the service repair is usually the dual run capacitor.A dual "run capacitor" supports two electric motors, such as in a large air conditioner or heat pump unit, with both a fan motor and a compressor motor. It saves space by combining two physical capacitors into one case.The dual capacitor has 3 terminals labeled "C", "FAN", and "HERM", which stand for the Common, Fan, and HERMetically sealed compressor.Sometimes but not always, when a condenser fan motor is replaced, the technician may install a "single" run capacitor just for that fan motor, which would only have connections labeled common and fan, now the Dual run capacitor only supports the compressor, and the condenser fan motor will have its own single run capacitor.Dual run capacitors come in a variety of sizes, depending on the capacitance, such as 40 plus 3uf, and also the voltage. A 440 volt capacitor can be used in place of a 370 volt, but not a 370 in place of a 440 volt.The capacitance must stay the same within 5% of its original value. Dual run capacitors are commonly used for air conditioning, and or heat pump, to help in the starting of the compressor and the condenser fan motor.I installed this capacitor myself without any problems and saved a ton of money on a service repair call. After much research I discovered that American Radionic is a top of the line leading manufacturer / engineering company building quality motor run capacitors with quality parts, built for the longhaul......The shipping was faster than projected, and I only had to stay under the ceiling fan in 82 degree indoor heat for 2 days. I feel that i bought a quality product and am confident that it will perform with longevity. American Radionic has one of the best warranties of any manufacturer.With a 5 year warranty and Made in USA ..............with all of that I feel I couldn't go wrong. ### ⭐⭐⭐⭐⭐ It works *by R***Y on Reviewed in the United States on 3 July 2022* A capacitor either works or not, this one works. Guess that's a 5 star. --- ## 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.co.th/products/366309164-40-3-uf-mfd-round-dual-universal-capacitor-replacement-amrad](https://www.desertcart.co.th/products/366309164-40-3-uf-mfd-round-dual-universal-capacitor-replacement-amrad) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-23*
