My AC works again!
My outside fan stopped turning, exhibiting the normal symptoms of a failed capacitor. I was able to "push start" the fan by manually turning the blade. This $10 part and 10 minute installation saved me a lot of money over a service call to my business!

Great alternative
HVAC friend recommended to replace what I currently had in my Trane XB unit. My god the company wanted for this part not the install. $200. Thanks AZ saved me a bunch of money.

Great replacement for our 20+ year old furnace, so far
This is working great in our old furnace. It was a inch or so taller but everything else was the same. So it fit into the original bracket without any modifications or adjustments. The old one crapped out all of the sudden. For $7 each I ordered 2 so that I have a backup and because I have 2 furnaces (one upstairs and one downstairs) that are the same model. So far so good and will update my review if needed. Make sure to discharge the old one before you go accidentally touching it and shock yourself trying to take it off!

Fixed the furnace overnight
I discovered on Sunday morning that my furnace blower wasn't working. A quick test with a meter showe a possible bad capacitor. It was going to be cold enough for frost so I tried finding a capacitor locally on a Sunday and nobody had it. Since I work during most supply house's hours I would have trouble getting one quickly. Amazon to the rescue with 4-8 am next day delivery. The furnace was running by 6:45 AM Monday. 4 stars becaus the tolerance is higher than factory part so I will still have to get a proper spec and keep this as a spare. Can't complain for $12.

Fixed our HVAC blower motor!
Outside AC unit is running, but nothing's getting cool - yikes! Crawled up in the attic (wow it's warm up there!) and discovered the "computer" is trying to run the blower motor, but it isn't going in spite of getting the correct voltage. I took a chance that the motor capacitor might be bad and ordered this. Thank you Amazon for super fast delivery - our house is cool again!

It is a relief to have the correct capacitor to fit the furnace. Fantastic to have the heat back on!
