The inside fan blows air through the ac coils to cool the air. It should be on a separate breaker or fuse circuit from the outside unit. See if there is a fuse box on the side of the inside unit and check the breakers in the house main breaker box. Also stand quietly beside the inside unit and listen for the fan motor running. If the motor is heard running then either the fan drive belt has broken, or the ac coils are clogged preventing air from flowing.

What should you do when your central air compressor is running but the cooling fan is not working?
Check the capacitor located inside the outside condensing unit,usually the fan,compressor are wired together,if one is running the other should be running
What is the purpose of an air conditioning fan?
the aircondition fan is located in the outside unit of a central AC unit. It sucks outside cool air thru the fins and tubing that contains heat from air collected from inside the house thru the A-coil that's sitting on top of your heating unit. The inside fan in the heating unit blows air thru the cold air moving thru the fins and tubing in your A-coil and blows that air into your house. If you hold your hand above the outside unit while the fan is running you can feel the hot air that's coming from inside, this is how the heat is removed.
Why would your AC be running outside but inside very little air is coming from the vents and it sounds like it does not kick on inside the house?
you need to check to see if the lines or outside unit has an ice build up. unit is probably working too hard, keep it at an even tempature, don't turn down and then turn up constantly. ====Aswer==== Better yet, check to see if the indoor fan motor is running. It could be a bad fan motor, bad capacitor, or bad fan relay.
What causes the inside unit to turn on with out the outside unit turning on?
There are a few instances that will allow ( I am assuming when your saying inside unit you are referring to the the circulation fan for your building ) the inside unit to run. Check the "mode" on your thermostat. Is selected to auto fan? this will allow the the fan to run continuously regardless if the air conditioning is cooling or not . If the thermostat is switched to the heating mode the furnace will be operating and the air conditioning unit will remain inoperative while the furnace mode is selected. Is the inside unit running and no cool air is being produced while the air conditioning mode is selected ? Contact your HVAC&R technician to trouble shoot the unit.
Will a heat pump compressor burn out if the circulation fan does not work?
If the fan outside is not running the compressor will overheat and if the fan inside the house is not running the compressor will get liquid refrigerant back to it and lock up! Neither is good for the compressor.
On a electric home heater unit does the outdoor part turn on when it is heating?
No, that is just for cooling. The heat from inside is transferred to the outside unit and removed by the fan.
What is wrong with central air unit when you turn it off and it stays on but the outside unit is off?
Is the whole unit running or just the fan? My thermostat has the option to run the fan only at all times and also runs the fan when the temperature gets too high (or low) in the house.
Should the outside unit be running when you use the fan or on option instead of turning on the AC?
The outdoor unit only runs in the AC mode(unless it is a heat pump). If you have the system off and the fan on, the outdoor unit should not be on. You can run the indoor fan only without harming the system.
What does the sensor light box with a fan inside represent on a mk 4 astra It is staying on while engine running?
I do think it is telling you fan is on at radiator. is unit getting what is temp
What happens when Air conditioner running but fan not turning?
I have to assume that you are referring to the fan on the outside Condenser Unit? The most likely causes are either a burned out fan motor, or a blown Capacitor on the motor startup circuit.
Air conditioner not blowing cold air on hot day?
The first thing to check is that the outside unit is running. That the compressor and the Fan is running. If they are running, then have the Freon pressure in the system checked. You may be low on coolant.
When you use the fan option on your central air unit does it draw air from the outside or circulate the air already inside?
It recirculates the air inside. If it brought in humid outside air, you would shortly have a meganormous mold problem.
