BOJACK 40+5 uF 40/5 MFD ±6% 370V/440 VAC CBB65 Dual Run Circular Start Capacitor for AC Motor Run or Fan Start or Condenser Straight

Our A/C started to act up over the summer. The compressor would try starting for a few seconds, and stop. Repeated several times until it finally turned on a few minutes later. I was considering hiring someone to fix it as I knew nothing about A/C's, but I am very much a DIY kind of person, so I did some research and found out the capacitor needed replacing. I purchased this, and I was able to replace it very easily. When turning the A/C back on, the compressor immediately came on, and it sounded like I gave it more life, too. It ended up being a quick, easy, and cheap fix.

As advertised. Working well so far. Good fit and good performance but I haven't had it long. Fast shipping and good price. So far, so good.

Did the job just fine

was not the same diameter, but I MADE THE ADJUSTMENTS. WORKS WELL.

My outside AC unit stopped functioning. What was happening is it would hum but the fan would spin. The fan motor would get very hot and then the unit would just shut off. At one point to diagnose it, when it went to go on and it was humming I took a stick and pushed the fan blades to see if they were stuck. It started spinning fine then. After doing some research it lead to the capacitor being bad. It holds an electrical charge and when the machine is turned on, it gives the motor that boost it needs to start up. Kind of like kickstarting a manual car with a bad starter.Not wanting to spend an fortune on a service call, I opened the side panel up with 3 screws and read the values on the current capacitor. I ordered the same value AC capacitor here for real cheap. So cheap it wouldn’t be a bad idea to get another one as a spare.To install it, I just took a picture of the current one to see which color wires go where. There was also a wiring diagram on the inside panel. The terminals fit perfectly and it’s just a metal strap with a screw to hold the capacitor in place. Once hooked up, in the disconnect box I flipped the jumper and then went back inside and turned back on the circuit breaker to the unit. I called for AC and it started right up!Problem solved. This was in a Goodman 2.5 ton outdoor AC unit that was installed in the fall of 2011. So the original part lasted 11 years.

More often than not, a bad capacitor is the reason why an HVAC system suddenly fails to operate.They are easy to install using basic tools .Match the ratings of your old capacitor and replace yourself.There are several videos showing the process.Perfect fit, perfect function.Fixed my system in 20 minutes.Starts easier, cools nicely, quiet operation.Inexpensive to try before calling a HVAC contractor.

Price was nice, it was a simple swap, fit great and worked no problem. It’s been installed for about 2 weeks or so in the middle of the East coast heat waves and so far so good.

It works. Went outside, fan wasn't spinning on the condenser unit and it was making a bit of a humming noise. I don't think you always get the noise, but once you do all the simple troubleshooting, I'd look here next. If the capacitor looks swollen or corroded--its probably bad. You can test it to verify, lots of videos online that can show you how (wordofadvicetv). Be careful if you do this work because it is dangerous if you don't follow basic safety precautions (again watch the videos).Anyhow, I got it from Amazon in 24 hours, and swapped it out in 15 mins. Much faster than calling a HVAC tech and at least $200 cheaper (assuming your HVAC guy is honest and doesn't just tell you your compressor is broken--then quote you $2000). I bought two just to have one on hand. I have no idea of the longevity of the product. I've got a spare now and if they don't last I'll update this post and let you know if I figured out if there is a more reliable version.
