My Central Air Stopped Working. When I Turn On The Central Air All I'm Getting Is Cool Air Blowing In Not The Cold Air. When I Look At The Central Air Unit The Fan Isn't Turning. What Should I Do?

How old is the unit? It could be that it needs some cleaning, or the motor is going out in it. I think you might want to unplug it and clean it first, then if that doesn't work, then I would call in the repairman. Hope this helps.

It sounds like your fan motor has burnt out. This sometimes happens because the contacts that kick the fan motor off, become worn and do not release, which in turn, causes the motor to run continuously without shutting off. The end result is that it cooks the fan motor.
We just had to replace ours because of the same symptoms you are describing.
If you or someone you know, is mechanically inclined, you can shut the breaker off to the A/C unit, remove the cage that covers the fan, then take the fan and blower moter off.
The fan is connected to the motor. 
Once you remove the fan, you will see the motor. Remove the motor. Write down the name and model number of your air conditioner, then take the fan motor with you to an appliance supply store.
They will sell you a replacement motor. I would go ahead and pick up a new contact as well. It's not that difficult to replace.
Just make sure that when you disconnect the blower motor, that you make yourself a little diagram on where each color wire is hooked up before you disconnect them.
The shaft on some replacement motors may be longer than your original one. If it is a little longer, that's no problem. If it is quite a bit longer, you will most likely need cut it down to size. Also not a bid deal, but you will have to have a saw blade that is made to cut metal.
I know it sounds a bit difficult, but you are looking at around $140.00 to do the repair yourself, verses several hundred to call a repairman.
Most A/C repairmen charge a minimum of $70. To $100.00 just to come out and look at your A/C unit. Then, there's the chance that you may not get an honest one, who might try to tell you that you are going to have to replace the whole unit. Which could cost you upwards of two grand, depending on the size of your unit.
