My unit has been running great for years then all of a sudden, the unit. Won't kick in when the power is turned on from the thermostat. I can hear a loud electrical buzz from the air conditioning unit, but the fan won't start up and run. Any ideas would be appreciated. It's an Intertherm unit, model CNS36BAVAA
A bad fan motor they will go bad is the blower on your inside unit or the condenser assembly outside either could be a bad motor
Sounds like a leak to me - if you have a set of guages available (know anyone working in the refrigeration field???) you could tell this for certain. Otherwise, try running it when it cools down outside and see what happens. Take a stick thermometer, and put it in between the fins on the INSIDE condenser coil. If they get cooler, but not down to about 50 degrees, then you are low on refrigerant.
Good Luck!

If you are talking about the indoor fan it is probably a bad capacitor. Replace the fan motor capacitor. And YES, if the fan motor needs replacing too, you can DO-IT-YOURSELF.

It is probably the compressor humming. They can make some funny noises especially on start for a while. If the unit is not cooling it may be the start capacitor or the comressor may be locked up.
