## Overview

The VEXUNGA 70+5 µF dual run capacitor is a high-performance, universal replacement designed for both 370V and 440V AC motors. Encased in a compact, heat-resistant aluminum shell, it supports dual motor operation (compressor and fan) with labeled terminals for easy installation. Rated for extreme temperatures and boasting a 60,000-hour lifespan, this capacitor ensures reliable, long-lasting performance for your HVAC system with a hassle-free, direct replacement fit.

## Description

This capacitor is used for start-up and operation of AC motors, such as Motor Run or Heat Pump Air Conditioner or Condenser Straight Cool.It is small in size, lightweight, heat resisting and anti-explosion. Model: CBB65 (Universal model). Case Material: unpainted aluminum case. Dielectric material: metallized polypropylene film. Available Capacitance: 70+5uf. Capacitance Tolerance: ±6%. Operating temperature: -40℃ to +70℃/-104℉ to +158℉. Frequency: 50/60Hz Operating Life:60,000 hours with 94% survival. Dissipation factor: 0.1% maximum. A VEXUNGA ac capacitor can be used in place of a 370 volt capacitor and a 440 volt capacitor. A capacitor is an electric component that temporarily stores an electrical charge. A dual "run capacitor" supports two electric motors, such as in large air conditioner or heat pump units, with both a fan motor and a compressor motor. It saves space by combining two physical capacitors into one case. The dual capacitor has three terminals labeled "C", "FAN", and "HERM", "Herm"/"H" for the compressor motor, "Fan"/"F" for the fan, and "C" for the common line.

Review: Easy fix that most home owners could do - Watched a YouTube video of the most common Central Air not working fixes. I went out and checked mine as it has not worked a couple of years. Sure enough, the main fan was working, but touching the compressor tube, you could feel it pulling every second or so, but not starting. Removing the old part and measuring it, the fan side was good and the compressor side was bad. Watch some YouTube videos if you dont know how to do that. It's not difficult. Anyways, after kicking myself in the butt for 5 minutes straight, I ordered a replacement here on desertcart. Product arrived fine and appears to be a well built part. Steps to replace it: 1)To start, most units have an outdoor circuit breaker you can pull to de-energize the unit. Pull that and/or flip the switch for the CA unit in your main fuse box. Next, remove the side access port on the outside unit, usually just two screws to get access to where the starter cap and relays are. 2)Checked the old cap to make sure it was de-energized (Very important step!!!). Do not touch those wires if it's still energized! If the unit is truely powered down and you still measure voltage on the old cap, you may need to discharge the old cap. Remember though, there are TWO caps in one and you need to discharge BOTH. If either still has a charge, they could give you a serious bite. Not to scare you away from doing it, you just have to be safe. 3)Marked the color of the wires and where they plugged into on the old cap. Note:Take a couple of pictures of the old cap and what wire goes where on it. This can be good to reference later! 4)Unplugged all the wires from the old cap and loosened the strap holding it in, and removed it. 5)Fit the new cap in under the strap, tighten it down but not so tight that it could dent the new cap, and plugged the wires into the new cap in the same positions as the old cap. Note: In most cases, the compressor will plug into the terminal stamped HERM. The fan goes to Fan if stamped. There are often two wires that were on the same terminal on the old cap, and that is the common. Plug all the wires in and DOUBLE CHECK you did it right. Take a picture of the old one at the start if you're not sure. 6)Put the side access cover back on the unit. 7)Reinstall the circuit breaker. Set the thermostat to turn it on and hopefully you have nice cool air blowing in a few minutes! 8)Especially if this fixes it, a very important step is to order a second cap!!! Then you dont have to wait long if it goes out. These get stressed every time the fan or compressor turns on. They do go bad eventually, so just have a backup ready. You will hopefully get a good 3-5 years out of the cap. In the attached picture, the temp was 78, now 71. Spouse and kids are happy. Therefore. I am happy.
Review: Perfect replacement. - Replaced the Totaline capacitor I had prior. So glad to have A/C at home again. Thought it was smaller than the capacitor I had on before. It is working perfectly.

### ⭐⭐⭐⭐⭐ Hope I never need to replace

I bought this as a spare to have on hand through Oklahomas hot summers in case our Air conditioner pops its capacitor. This replacement is quality at a great price, cheap insurance
