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.

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 great. Would buy again.

Good item. Does the job for AC

Good

he ones prior didn't work well, It was an excellent choice

I bought this cap 01/2023 as a spare in case my cap went out. It did. It was 364 days ago, yes, it lasted ALMOST a year. The fan would hum and get hot. I swapped it out for another BoJack cap and I am back in business. I tested the BAD BoJack cap and had NO reading between C and FAN - BAD CAP!!! (C and HERM was within tolerance). Send me a new cap guys!

It installed perfectly in my portable AC unit. The unit would blow air, but was not cold anymore. I replaced this and it took care of my problem. There are two kinds of capacitors. Run capacitors and Run/Start capacitors. Ensure that you have the correct one for your application bc they are not interchangeable. Run had 2 prongs while the run/start has 3 prongs. Capacitors essentially act like a “jump start” of power to keep an engine with running or allows it the needed energy to start the motor running. Both of these require a little more power than is available from the electrical circuit. It’s more complicated than this, but this should help answer some of your questions. Thanks for coming to my Ted Talk.

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!

Good product

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

Worked out of the box. Beware when installing as the old unit needs to be powered off by touching with a rubber handle screwdriver touching the two contacts at the same time. shut off and remove the fused for you thermo pump. You have been warned!

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
