The fan is working fine, but you can hear when it tries to kick into cooling mode. Sounds like the compressor tries to kick on for a moment, and then it switches back to just fan. Happens in all cooling modes. Tried turning it off for a couple of hours. No difference. Unit is about two years old.

Hi, The problem here is the compressor.... it has failed and will not start. You can try to replace the capacitor and see if it will go but most likely the compressor is toast. I t will cost more to replace it then to buy a new unit.
Here is a tip about troubleshooting your air conditioner... There are many things that can cause your air conditioner not to cool...
That thing connected to the capacitor is a booster for the compressor .But if the outside fan doesn't work , the compressor will shutt off on overload because the high pressure in the condenser coil.
First try to replace the capacitor in the condensing unit (it's the only one that works for the compressor and the fan motor) ,but if the fan doesn't start, you need to replace the fan motor.
it sounds like either the start components for the compressor have failed or the compressor itself has failed, since it is not kicking the breaker I would lean towards start components.if it is a PSC only comprssor, you may be able to add a start assist to get the compressor started. I assume that since it is 8000 btu it is 110VAC you can probably get a generic start kit at your local appliance parts house. they have a diagram and are fairly easy to install, just be aware that the capacitor storea charge on the OFF cycle, and can be dangerous
If blower not working, and yoou hear a slight "Hum" with fan only on, try this. With power off to AC. Go up on roof, and slide a stick through opening on side near rear, and try to get to fan blades at rear of unit. try to spin the blades a few times, even if it only goes a little at a time. Unless you want to take all those screws out & remove cover to get at it better, but watch for wasps under there. Give fan a couple of full rotations, then have someone turn it on to fan only & see what happens. If fan finally works, let it run for a few minutes on fan, then try cool & see if it all comes together again. Let me know.
Take a look at your start capacitor. This the capacitor that kicks the compressor over when it tries to start. If the capacitor is bad, it cannot kick the compressor back over after the first cycle because the head pressure has not evened out yet. It is located in the upper unit on the side panel in a small box. Be careful, highly charged capacitors can zap you if you are not careful. Disconnect power and touch across the terminals with a meter or a screwdriver to discharge the capacitor.
