## 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 . Air conditioner capacitor is small in size, lightweight , heat resisting and anti-explosion . 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 . 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 . 40/5 uF Capacitor Replacement for 97F9838 , Z97F938 , 97F9838BZ3 , 12786 , RC0108 , 97F9849 , C3DR405 , Z97F9848BZ2 , P291-4054RS , C3405R , HCKS400D050R440Z , P291-4053RS , TT-CAP-40/5/440R , TRCFD405 , TP-CAP-40/5/440R , HC98JA041 , HC98CA040 , HC98CA041 , HC93CZ035 and so on. Package contains 1piece x VEXUNGA 40+5 uF 40/5 MFD 370/440 VAC Dual Run Start Round AC Capacitor.

Review: Well worth the money - Excellent replacement part. Easy to install as I took a photo of the old one with wires attached and moved one wire at a time to the exact same spot on the new one. It took me 5 minutes from removing, connecting and installing. AC started right up. Saved over $200 the AC company wanted to charge to replace it. Excellent YouTube videos to show how to discharge electricity from old unit so u won’t damage the unit or yourself. Simple.
Review: Good unit. - perfect and matched nicely. Only in use for 6 weeks but working well. My old one lasted 8 years, so I'm hoping this one last a while. HVAC company wanted $400 to replace and I did it in 10 minutes with this. Caution, Shock - electrocution warning. These store electricity and are dangerous when they are in use.

### ⭐⭐⭐⭐⭐ Works great, make sure to map the connectors correctly.
*by �***I on July 15, 2024*

The product works as intended. Aside from the post diagnosis time (I'll explain later) this took me 10 minutes to replace my AC capacitor, including turning off the power and replacing the capacitor. There two important things to know here: it matters less what brand you get. It matters waaay more that the capacitor you get matches up with your air conditioner's capacitor specs. If the old capacitor asks for 45+5uf, then get a capacitor that matches that rating. The voltage should also meet or exceed the air conditioner's specs. The other thing you keep inind is pay attention to the cable colors and connect them correctly. My old capacitor was bulging and all rusted out so I could not see what the original terminal labels were (C,F, HREM). I took a picture and hooked up the new capacitor the same way as the picture. When I turned the power back on, the compressor turned on for few minutes then turned off. I was going to call the HVAC repair people until I stumbled upon a post where if you hooked up the capacitor incorrectly, the compressor fan will run for a bit but then turn itself off because it is running out of spec. The air conditioner cover has your AC's wiring instructions, including what color wires should be plugged into your capacitor. Redoing the connectors as noted in the instructions did the trick. don't rely on the old capacitor's wiring position, and dont expect the wiring colors to be the same between HVAC companies. If you replace your capacitor and it short cycles recheck your connections before calling the pros.
