Featuring a durable aluminum casing and snap-in mount, it supports both compressor and fan motors with clearly labeled terminals. Engineered to perform reliably across a wide temperature range (-40℃ to +70℃), this capacitor ensures stable, efficient operation for air conditioners, heat pumps, and condensers, making it an essential upgrade for maintaining peak system performance. ## Description Product description VEXUNGA Dual Run Start Air Conditioner Capacitor A capacitor is an electric component that temporarily stores an electrical charge and AC capacitor is a key component to start air conditioner motors. A dual run capacitor supports "TWO" electric motors , one section for the condenser fan motor and the other for the compressor motor . Beacause of technological innovation, the dual run capacitor can saves space by combining two capacitors into one case. Round cylinder-shaped dual run capacitors are commonly used for air conditioning, it can help in the starting of the compressor and the condenser fan motor . Capacitors come in a variety of sizes, but depending on the capacitance (µF or MFD) and the voltage. VEXUNGA Air Conditioner Capacitor is A Good Choice !!! SPECIFICATIONS Model: CBB65B （Universal model） Operating temperature: -40℃ to +70℃/-104℉ to +158℉ . Frequency: 50/60 Hz . 45/5 MFD Capacitor size measures ( 2.36inch / 60mm ) in Diameter x ( 3.35inch / 85mm ) in Height. Dual capacitors have three terminals, three terminals on the top are labeled "Herm"/"H" for the compressor motor - White Cap , "Fan"/"F" for the fan - Green Cap , and "C" for the common line - Black Cap . "WHEN” to Replace AC Capcitor - The air conditioner's fan wouldn't spin - stopped working . - The air conditioner hummed , but no air flow. - The ac fan would spin intermittingly and the external pump would not start . - The air conditioner stopped cooling - the compressor in the condenser maybe not coming on. - As the capacitor gets older , the motor may get louder and seem to run slower . You can extend the life of your motor if you replace them before they become weak. Eventually the capacitor will become too weak to start the motor, and if the motor won't start it may be shorted. Timely replacement of capacitors is crucial to air conditioner maintenance . "VERY EASY” to Replace AC Capcitor First of all, Turn off the power to the air conditioner. Secondly, Take out the ac capacitor. Finally, Make sure that you know which wire is for which terminal - direct replacement without changing wiring or adapters & Confirm the appropriate capacitance (µF or MFD) and voltage. What's important, Replace air conditioner capacitor by yourself that will save you a lot of money and time . Notice: After installation, please shake the capacitor gently to check whether it is firmly fixed. If the capacitor is found to be loose, it needs to be fixed again until it is confirmed to be stable and not shaking before starting the motor. Package contains 1piece x VEXUNGA 45+5 uF 45/5 MFD 370/440 VAC Dual Run Start Round AC Capacitor. Matching Notes Size Matching : The capacitor's dimensions may differ from your original specifications. We recommend verifying the actual installation space, wiring distance, and other matching requirements to avoid impacts on subsequent assembly and use. Voltage Matching : Please ensure that the capacitor's voltage specifications fully match your device's requirements. A voltage mismatch may cause device malfunction or capacitor damage, impacting safety and performance. Important : Before installing this capacitor, be sure to inspect the components in the corresponding mounting area of ​​your device to ensure they are free of damage, looseness, or deformation before proceeding. This ensures safe assembly and device stability. ## Features - VEXUNGA 45+5 uF ±6% 370/440 VAC CBB65 dual run start capacitor replacement for BOTH 370 & 440 Volt capacitors. - 45/5 MFD Capacitor size measures ( 2.36inch / 60mm ) in Diameter x ( 3.35inch / 85mm ) in Height. - Operating temperature: -40℃ to +70℃/-104℉ to +158℉.

They come in a range of sizes. **Q: will this work for replacing 97F9899 Genteq Capacitor?** A: The capacitor is a 45/5. The 45 for the hermetic and 5 for the fan. The voltage should be in range. The number should be on your old capacitor. The data I have states that it will work. **Q: My old capacitor has a 5% tolerance rating. Can I replace it with this one which is rated at 6%?** A: The tolerance rating is not as important as the voltage rating. Your 220VAC system can be as high as 230VAC. The tolerance is referring to the amount of farads, which will make your motor run faster or slower. **Q: USA made** A: No ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***N on October 9, 2025* ### ⭐⭐⭐⭐⭐ Review *by S***B on August 29, 2025* ### ⭐⭐⭐⭐⭐ Review *by O***X on July 27, 2023* ## Frequently Bought Together - 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 - BOJACK 1 Poles FLA 30 Amp Coil 24 VAC Air Conditioner Condenser Compressor Contactor AC Definite Purpose Contactor - [UL Certified] BlueStars 45+5 uF 45/5 MFD 370V or 440V Round Dual Circular Run Capacitor CBB65 50/60 Hz - Compatible for AC Motor Run or Fan Start or Condenser Straight --- ## 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.us/products/521021195-vexunga-45-5-uf-45-5-mfd-370v-or-440v](https://www.desertcart.us/products/521021195-vexunga-45-5-uf-45-5-mfd-370v-or-440v) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-22*
