My air conditioner (main unit outside the house) has stoped cooling. I have a programable thermostat. When I turn the AC on it only runs the fan.
What do you think It is, AC problem or thermostat??
The symptums you are asking about your Air Conditioner, It is a problem with your Air Conditioner but without diagnose physically we can't say any thing whatever could be reason of air conditioner not working.
Thanks & Best Regards

By the sounds of the symptoms that you have expressed it appears that your AC has an issue. It all deepends on what make and model you have. It may be a couple of different things, but it doesn't sound like its a difficult diagnosis.

As you dscribe symptoms of your Ac has possibility of bad capacitor or compressor wire burne out or low refregerant or compressor internal overload but it must be diagnostic by profession Ac technician to come and look at the problem.
Wish you all the best
There is a chance it has to do with a low coolant level, but more than likely, you are running it a little too cold and it has frozen the line. You can see this if you look at the copper pipe that runs from the compressor on the outside of the home...if there is an insulating wrap around it, underneath it there would be a fair amount of frost or even ice.
Whenever there is high humidity, and the temperature is set low, and the compressor has to run for extended periods of time, this type of thing can happen...verty common actually.
Save yourself an initial visit charge to a HVAC conrtractor, shut off the a/c for 4 or 5 hours, then turn it on at a setting of just below the current temperature in the house. Check to see if there is cooling at the floor register. If so, this is probably all it was. Set it to a reasonable cooling temperature (22 or 23 celsius) and keep your doors and windows closed to prevent forcing the AC to overwork. If this didn't solve it then call an HVAC contractor.
I would say the same thing, frozen a/c if you let it run all day and all night at lets say just 15, its frozen for sure, stop it for at least 2 days to let it melt back to normal and try again, I was like that to like to put it low its cooler in the house (FALSE) now I bring it at around 18 and its still cool when you come from outside at a 35 degree sun!
Try this and let us know the results if you don't mind.
Thanks and good luck.
