BOJACK Dual run circular start capacitor
Ombines two capacitors into one unit. Three terminals on the top are labeled "Herm"/"H" for the compressor motor, "Fan"/"F" for the fan, and "C" for the common line.It will power a compressor motor and a fan motor
Model: CBB65(Universal model)
Shell material: metal
Dielectric Material: metallized polypropylene film
Capacity: 45+7.5uf
Tolerance: ±6%
Rated voltage: 370V/440 V AC
Frequency: 50 / 60Hz
Safety rated: 10,000 AFC
Operating temperature: -40 ℃ to +70℃/-104℉to+158℉
This capacitor is used for start-up and operation of AC motors with
frequency of 50Hz/60Hz such as Industrial Grade Replacement for
Central Air-Conditioners, Heat Pumps, Condenser Fan Motors, and
Compressors.It is small in size, lightweight, heat resisting and anti-explosion.
Round capacitor can be used to substitute oval shape one with the
same MFD AND Volt specs.A 440 volt capacitor can be used in place
of a 370 volt, as it is build better, but the 370 can’t be used in place
of a 440 volt.

My aging A/C unit's fan was not spinning. I suspected the capacitor, and after some research, I decided to give this BoJack model a try. I'm so glad I did!Installation: I'm not an electrician, but I was able to replace the old capacitor myself. It was a simple swap, just matching the wires and securing the new one in place.Performance: The difference was immediate. My A/C fired up right away, and the fan was blowing strong and cold. It's been running smoothly ever since, and I'm confident that this BoJack capacitor has given my unit a new lease on life.Quality: The capacitor feels well-made and sturdy. It's a good size and fit perfectly in my A/C unit. The terminals are clearly labeled, which made the installation even easier.Value: For the price, this capacitor is an absolute bargain. It saved me from having to call a repairman or, worse, replace my entire A/C unit.Overall: I highly recommend this BoJack dual run capacitor. It's a reliable and affordable solution for reviving a struggling A/C unit. If you're having similar issues with your air conditioner, don't hesitate to give this a try. You won't be disappointed.

I live in Texas. Needless to say it is extremely hot. I noticed my home wasn’t cooling late on a Saturday night. Went outside and the compressor fan wasn’t coming on but I could hear the compressor making a humming sound. Amazon overnighted this part to me. Easy install. Compressor fan came right on after install. My home is cooling again. Quick DIY inexpensive fix.

Competitively priced, arrived with prime 1-day shipping, and most importantly it worked as advertised, no issues. It perfectly replaced my genteq 97f9883 capacitor for less cost than the OEM Part. If you have 2 units, I recommend ordering 2 as my second unit failed almost a month after the first.

My 4 year-old outdoor A/C unit made some groaning noises and then the compressor refused to start on a 100 degree day (of course!).After having replaced the starting capacitor on the A/C at a previous house (also about 4 years old at the time it failed), this was my first guess as to what the problem might be. I measured both sides of the old capacitor after disconnecting the leads, and sure enough, the 45 microfarad side measured only 3.5.After checking the usual home stores on a Saturday night and finding nothing, I got on Amazon. I found this unit could be delivered the very next day, so I ordered it. From the time I ordered until it showed up at my door was less than 12 hours. Bravo Amazon!This capacitor fit quickly with no issues, and I had the compressor running quietly at full speed in less than 20 minutes. Interestingly, it draws about 1 amp less now, so bonus points for that on my next electricity bill.An expensive service call was avoided, and my family got cold air again quickly!

While installation did require the ability to read a schematic for the AC electrical system it was intuitive and saved me a bundle on repair costs.

This replaced a 370v capacitor, which was a smaller diameter. I had to fashion a new strap from sheet metal, then move the capacitor up about 1” and to the left maybe a 1/2” to get it to fit inside the cover/compartment.Trane XR model 4TTR3042D1000NA

Trane XR15 heat pump. Exact fit and replacement for the 11-year old OEM capacitor. Easy to install, in less than 15 minutes total from start to finish.
