Usually compressor not running or low on refrigerant. And yes it is supposed to be warm
the compressor is not running. Check your breakers.
warm air, the heat is what is being taken out of the inside of the house.
Your compressor is not working. Through evaporation compressors cool the evaporator coil and the fan blows air across it. So if the fan is blowing hot air the compressor is not cooling the coil. But check to see if the dial inside the fridge is turned to "more cold" , that turns the compressor on.
It may seem obvious, but it can happen. As you were setting the thermostat, you could have flicked the selector switch over to "heat" instead of "cool." If this happened, then the reason you feel the hot air blowing from your system is because the heat is on. Simply move the switch to the "cool" setting to start chilling out. Check the outside unit. This is where your compressor and condenser coils are located. Make sure the outside power switch is turned on to power the compressor. Without power, the system might run from the inside air handler, but it will not cool. Also check to see if there is debris such as leaves or other items blocking the air intakes on the system. This also can prevent proper cooling. Checking for airflow restrictions around the outside unit should be a regular maintenance routine.
If cool air is blowing but doesn't seem to be very much, and the house feels damp and muggy, it is probably because the outdoor A/C unit is not functioning properly. The compressor should be checked.
No the out side fan is for venting heat away fromt he unit.
Is it a central unit? check and see if the fan and compressor are running in the outdoor unit. The system may be low on freon or the compressor may not be running. It is best to call a qualified HVAC technician.
runs for 4 min or whatever the limit switch is set at
Turn it on high
it keeps the refridgerator cool
It will run until the high pressure safety switch (assuming you have one) trips it out or the compressor dies if you don`t have one. If you must run the ac, put a lawn sprinkler or a hose nozzle set at mist and aim it on the coil to keep it cool until the fan can be repaired.
so its not blowing at all anymore, as in no air at all? if tahts the case then how do you know its still cold. if it isn't blowing as well you may just need to change out your filter, just like in a house all cars(most)have a air conditioner filter. if its not blowing anymore at all it sounds like your compressor or your whole dam motor went out, take it to shop.
