Usually compressor not running or low on refrigerant. And yes it is supposed to be warm
the compressor is not running. Check your breakers.
The condenser outside is supposed to blow out warm air. It releases the heat absorbed from inside the house by the refrigerant, which helps cool down the indoor space. If it is blowing out cool air, there may be an issue with the HVAC system that needs to be addressed.
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.
There are several possible reasons why your AC may not be blowing cool air. It could be due to a lack of refrigerant, a dirty air filter, a malfunctioning compressor, or a problem with the thermostat. It is best to contact a professional HVAC technician to diagnose and fix the issue.
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.
Your outside AC unit may be blowing cold air because it is functioning properly and is working to cool the air before it enters your home. This is a normal operation of an air conditioning system.
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
