Cap was completely shot, replaced it and so far so good.
post # 2 was the first tip to test the capacitor ...... post # 29 coil was cleaned, and installed hard start kit ........ should have tested the capacitor at the beginning of this post. :furious:
At this point, you need tell us what you did so far to fix this problem.
1- Post some images of the condenser
2- Visual inspection and voltage drop across the contactor
3- Measure motor fan and compressor amp draw
4- You need to test resistance/short to ground of the compressor windings
5- Leave AC running for 15 minutes and check high and low pressures
Let us know the results of these tests
You had 243 across two legs at the contactor of 120 which in all actuality were 12? per leg or each side. If you check from one terminal to ground (you can use the ground lug in the condenser) it will show you 12?. From terminal to terminal is 243 which is the total of two individual legs, single phase.I did check the contactor, I had 243V on each side.

I have a strong hunch that you're going to need a new compressor.
Then that's it, bud. Congratulations!
I was going to also suggest that possibly the breaker was weak..good job!
Does this make sense? If the fan motor was cutting out if would over heat the compressor causing it to shutdown?
I think I had 2 problems. 1 was the cap on the compressor and 2 was the cap on the fan motor. I just didnt find the fan motor cap the first time because it was disguised.
It makes sense that if one goes out the other does not work so yes. A condenser contains extremely hot refrigerant in vapor form, from cool low pressure vapor to hot high pressure vapor right through the compressor. The fan draws air through the coils, cooling the hot vapor off enough to condense into a liquid to be shot back up to the evaporator coil to then evaporate and that is the complete cycle so guess what happens when the fan goes out in the condenser? Yup, that vapor isn't cooling off. Combine that with the regular heat of the compressor running and too hot and overheating is inevitable.
You should be good, but I'd really like to know the pressures. Did you get the gauges?
I am sorry for not being very clear, this is my first home and first AC to really work on. Luckly I can buy parts from Johnstone Supply so this problem only cost me $18. Thats everyone for their patience! I knew I could do it. The 2nd cap did throw a wrench because it was hidden.Glad to hear the unit is operating fine now. The trouble shooting problem came from Post #1 Op said outdoor fan was blowing cool air. #13 fan running. #25 outside unit making noise giving the impression outside fan running. Good job guys working with blinders on.
