BOJACK 50 uF ±5% 50 MFD 370/450 V CBB65 Round Run Start Capacitor for AC Motor Run or Fan Start and Cool or Heat Pump Air Conditione

I recently purchased the BOJACK 50 uF ±5% 50 MFD 370/450 V CBB65 Round Run Start Capacitor for my air conditioning unit, even though I ordered the wrong one by mistake, and I couldn’t be more satisfied with its looks ! This capacitor is a fantastic replacement part for AC motors, fans, or heat pump systems, and it’s been a game-changer in getting my unit back to peak efficiency. The build quality is impressive—sturdy, well-designed, and clearly made to withstand the demands of continuous operation. Installation was straightforward, thanks to its standard round shape and clear labeling, which made it easy to integrate into my system. Since installing it, my AC has been running smoothly, with no issues in starting or maintaining consistent cooling. The dual 370/450 V rating offers great versatility, making it compatible with a wide range of systems, which is a huge plus. What really stands out is the reliability. The ±5% tolerance ensures stable performance, and I’ve noticed improved efficiency in my unit’s operation, which has been a relief during hot summer days. For the price, this capacitor delivers exceptional value, offering OEM-level quality without breaking the bank. If you’re looking for a dependable, high-quality capacitor for your AC, fan, or heat pump, I highly recommend the BOJACK 50 uF CBB65. It’s a solid investment that gets the job done right! I returned this item as I ordered the wrong size and have the right one on the way. Shipping was really fast and the ordering process was easy. The packaging was really well structured keeping the capacitor safe during transit.

Perfect! Worked well for old Honda gx390 6500 watt generator. Wasn't producing power and replaced this capacitor and after install had power again.

A little undersized but it worked great for my portable ac. I have nice cold air now.

Works great and good quality, but if you are using it for a motor and it needs to fit inside a cover a weatherproof cover, just be aware that it’s a tiny bit bigger than most capacitors and check the dimensions before ordering. I didn’t, unfortunately.

Inexpensive fix for a pool pump or air conditioner. Find out what your air conditioner uses and order one today so you don’t have to wait a few days for it. You will use it eventually. Just be sure to pull the local disconnect first.

When my air conditioner suddenly stopped cooling, I thought I was in for an expensive service call. After some research, I realized the capacitor was likely the culprit, so I decided to replace it myself. This capacitor was a perfect match, easy to install, and got my AC unit running again in no time! Within minutes of installation, the unit powered back on, and my house was cool again. The quality feels solid, and it functions just as expected—no issues at all. The fact that I was able to solve the problem myself saved me hundreds of dollars in labor costs. If you're experiencing AC issues and suspect the capacitor, this replacement is a lifesaver. It’s reliable, affordable, and gets the job done. Definitely worth keeping one on hand for future maintenance!

Worked and now having to replace 5 months later.

Excellent!!

It is a bit bigger than the capacitor in my dehumidifier, but I was able to make it work with a few cuts to the dehumidifier’s plastic housing. It was a fairly easy replacement while following a couple YouTube videos and was my first time replacing a capacitor, so you can definitely figure it out too. The dehumidifier runs great now!

Saved me butying a new thermopump..Works perfect..

Good product

Fixed generator worked out well

A year ago May bout a new portable Air conditioner.Set it up for summer and surprise Compressor capacitor dead . Found this one and looks identical to original but different brand which is nice as the other didn’t hold up . Installing this tonight or tomorrow. Will be nice to have AC again
