Simple install, fixed AC without an expensive service call!
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 wouldnโt 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 itโs 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.

Capacitor that slaps, No Cap.
Did exactly what I needed it to do. AC has been working great ever since replacement. Easy to install. Saved me $200+ from calling an HVAC tech. May not fix all AC problems. If you're not a licensed tech, do your research and make sure you watch plenty of how-to vids. Capacitors can store charges even with the power off and will zap the you.

Easy to replace and works great
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.

Works Great
After our unit went down, I priced the cost to have someone fix but the cost was crazy high. I went on AI assistant stated the issues and within a minute I had my answer along with instructions on replacing the part. Less than 15 minutes, after receiving the part, our unit was up and running with no more issues!

I have a working AC again
I gambled and bet that my Ac wasn't working due to my capacitor. Similar thing happened a few years ago and the HVAC guy showed me how easy it was. I wasn't about to wait two weeks in the hottest summer ever, I decided to take a swing at it. Now I am no longer living in a hot house. Fair warning, my original capacitor was a narrow and tall part & this one came in short and stubby. I was able to leave mine on a corner of the service access on my AC unit. If I wasn't passing out from heat stress, I would take pictures of the product and compare them. Always have the power off and learn how to safely discharge your capacitor before removal. Pay attention to the wiring of your capacitor, take a picture if you have to. God bless and have a good day.

Had I called in a technician I would have to replace my AC unit at a cost of more than $7000. But this little piece of miracle saved me. very simple to change.
