AC compressor not kicking on

I have an in wall Kenmore 240v unit. When I turn it on all functions work but the compressor doesnt kick on. It buzzes for a while every couple minutes and eventually works. What should I look for?

It will have a capacitor inside used to start the compressor. That cap could be bad.

For more detailed info..... I'd need the full model number. xxx.xxxxxxxxxx

Well Wayne is WAY too far from me. And, it would more than likely cost more to just diagnose it than a new unit would cost

If you pull the front grill cover off it should be visible. Sometimes it's in one of the corners.
It will not be a calk walk repair. It will have to come out of the wall, be set on something sturdy and the casing removed.

Ok sorry for taking SO long, life got in the way and it was running ok. Now its back. The model # was very hard to read but I finally got it. Its 25373185300. I beleive its the capacitor as its makes a loud buzzing sound several times and eventually works. Sometimes I gotta turn it on and off several times. The only 2 capactors I found are $200!

What are the specs on the capacitors?
They aren’t that expensive. And they really have no way to make noise.
Test them with your meter to see if they are working correctly.

5303300180 dual capacitor.............. 370vAC - 35 + 5 mfd.

I don't know why that particular cap is so expensive. It is discontinued but it is also a common size.
Many places sell a replacement with matching values. The diameter may be slightly different.
Replacement capacitor

Thanx guys. Does the issue Im having sound like the capacitor? If they dont make a noise is the buzzing maybe the compressor trying to kick on? If the capacitor IS bad why does the ac eventually work?

That is a dual capacitor. One half is for the compressor and the other half is for the fan.
It is very common for just one side to go bad requiring replacement of the entire cap.
