My question is before calling a professional how can I possibly troubleshoot the problem. I notice that when I do turn my thermostat on inside that the fan on the outside unit does not kick on which is why I'm sure that I'm getting the luke warm air inside.

the things to check are 1 circuit breaker for outside unit...2 capacitor on on outside unit could be bad...if it is swollen or is oily it is bad...3 bad contactor ....if the inside unit is running there should be a buzzing noise on the outside unit..this would be the the contactor energized..if it is buzzing then 1 no power 2 bad capacitor.... if it is not buzzing 1 bad contactor 2 low freon pressure switch could be bad(was it coooling good before it quit coming on ) if yes then low freon will not be the problem 3 broke thermostat wires close to outside unit...

First check the filter
Second, have you been running it really low? It could be frozen. If so, turn it completely off for about half a day. Then turn it back on. Running it on really low temps for any amount of time can cause the unit to freeze. I once had an a/c company service my unit, left it down on 68 and it quit working. They came back out and gave me an estimate of almost 1000.00 to fix. When I saw the thermostat set so low, I turned the unit for the day (sucked since it was Labor Day in Phoenix). I turned the unit back on and it worked like new.
Third, freon leak?

The AC was working just fine, there has never been an issue before. The wife and I went to supper and when we returned it wasn't cooling. the fan is working inside, there is power on the out side, you can hear the the compressor humming. The capacitor was bad and I bought and installed it. The compressor still didn't come on so I took the coil down to where I bought the capacitor and he tested it first and said it was just fine. So I re installed it. The little plunger on the coil does click down and then it begins to hum but nothing else happens. Any other suggestions?

All you can do is reset the safety system if it has been tripped.
Turn off the electrical supply to the entire system from your main house electrical board. Then by just turning this switch or circuit breaker back on again you have reset the system, that is if the cause is not continuously there.
During hot spells some air conditioners can go out on high pressure or high temp safeties. Reseting after the event can bring the system back online.
If this doesn't work you will have to call for help.

The problem could be one of many. The first thing I would look for is a bad capacitor in the outside unit. It is silver and usually oval shaped. If the top is swollen then it is bad. The next thing could be a bad contactor. Look for burndt contacts in the outside unit. The third thing could be a bad fan motor. Make sure that you turn your power off to the unit before opening the outside unit up.

You have already diagnosed half off the problem, and you probably didn't even know it. You have diagnosed that the problem lies in the outside unit. It could be a number of things. Such as, low refrigerant switch tripped, a blown fuse in the disconnect, a capacitor has blown, or something electrical with the Almighty Compressor. I would suggest to call a qualified contractor who you trust to take a look at it.

Check the lines running from the AC unit. If you can see ice on the lines, shut it off to let it thaw out.
Also could be that there is not freon inside (leak) and it will need to be charged.
If the AC unit itself is not running, check the power shutoff (usually near the unit) to see if someone has turned power off at the unit.
