The fit was correct and everything hooked up without any issues. Once installed, the heater started working great immediately. No humming, no delays it did exactly what it was supposed to do. Solid replacement part and saved me from a more expensive repair. Would definitely buy again. Review: Solid product and a good value - Capacitors are wear items that are best either proactively replaced before they go bad or, at the very least, you should keep a properly rated spare on hand for when the one in your current AC unit inevitably quits. Furthermore, replacing a capacitor is a job that is well within the average DIY’er with nothing but the most basic tools required. There are plenty of YouTube videos on how to do it and do so safely. That is, unless you want to pay an HVAC repair company $200/$300/$400 or more when your capacitor quits (and it will eventually) on the hottest day of the year. Yes, that is what they charge to replace a capacitor. This Blue Stars brand dual run capacitor arrived promptly and when tested with my Klein MM700 multimeter was almost spot on the label rating and well within the claimed 5% tolerance. Replaced an aging Dayton (Grainger) part number 2MEK3B of the same specifications (50 + 7.5 mfd) in a 20 year old Lennox central air unit (not the original capacitor). The dimensions of the Blue Stars capacitor (both diameter and height) matched the Dayton unit being replaced exactly and were consistent with the product listing. The capacitor being replaced was still working and tested OK so it will go on the shelf as a spare. The capacitor itself is clearly marked (C=common, FAN, and HERM (compressor)). Terminals feel solid as does the metal (aluminum) casing. Did not weigh it but felt as heavy (if not slightly more) than the capacitor it was replacing. The product labeling clearly shows China as the place of manufacture but claims it is UL (USA) and CE (Europe) certified (but I have no way to verify this). Product listing in desertcart states a 100% lifetime warranty. Can’t vouch for that either. When installed and tested, the AC unit fired right up with the new capacitor. Far less expensive than I could find locally (Southwest Ohio). Certainly inexpensive enough to either purchase to have a spare on hand or, like me, proactively swap out an aging part before a problem occurs so I could do it at my convenience and schedule. As noted above, replacing a capacitor is not rocket science and within the ability of anyone that can replace a household light switch. Just make sure you get a capacitor of the right microfarad (MFD) rating for your application and TURN OFF THE POWER before you even think about starting the project. This means either flipping the circuit breaker in the main panel for the AC unit off or using the exterior safety disconnect switch where the AC interconnects to the house power. Simply turning off the switch on the furnace or thermostat IS NOT ENOUGH. Also, a capacitor, even one that has failed, can hold a residual charge and, therefore, make sure you discharge the old unit. Again, there are many videos available on how to do this and do it safely. Do some homework if this is new to you as saving a few dollars is not worth a serious injury or electrocution. Can’t comment yet on durability or service life but will update if it fails prematurely. Otherwise, a good solid product and an excellent value. Five (blue) Stars.

Both are combined into a single round unit with three labeled terminals (Herm, Fan, Common). **Q: Is it a certified capacitor?** A: Absolutely. The capacitor is UL & cUL listed, CE, and TUV SÜD certified, ensuring it meets high safety and performance standards. **Q: How do I know this is the right part for my AC?** A: Match the specifications: If your current capacitor says 45+5 µF, 370V/440V, this is the correct replacement. You can also check your unit’s manual or consult a licensed technician. **Q: Can I install it myself?** A: Yes, There is no wiring or adapter changes are required. Three terminals on the top are labeled "Herm"/"H" for the compressor motor, "Fan"/"F" for the fan, and "C" for the common line. (Always turn off power before handling electrical parts.) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy install, fixed the heater right away *by R***L on January 29, 2026* Installed this BlueStars 7.5 µF capacitor as a replacement and it was super easy to install.

Installed it in a pool heater, working great. Instead of client buying a new one for $3,500.00 and$1,000.00 to install, a $23.00 capacitor did the trick. ## Frequently Bought Together - BlueStars Upgraded Version 45+5 uf/MFD 370 or 440 Volt VAC Round Dual Run Capacitor CBB65 50/60 Hz - Compatible for AC Condenser Straight Cool or Heat Pump Air Conditioner - BlueStars Universal Fit 400-480 uf/MFD 165 VAC Round Motor Start Capacitor 50/60 Hz AC Electric Replacement Part - Lifetime Up to 30.000 Hours - VEXUNGA 45/5 uF 45+5 MFD 370V or 440V Dual Run Start Round A/C Capacitor 45 5 uF 370 440 Volt VAC CBB65B Air Conditioner Capacitors for AC Unit Fan Motor Start or Heat Pump or Condenser Straight Cool --- ## 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.dk/products/339723624-50-7-5-uf-370-440-vac](https://www.desertcart.dk/products/339723624-50-7-5-uf-370-440-vac) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-25*
