the fan should be blowing air out of the unit,as far as the direction different brands use differentdirecton fans to accomplish this
Replace the entire fan assemby.
drain is clogged. or there a hole in drain pan.
Perhaps a bad fan motor? Perhaps a bad fan resistor? Perhaps a plugged evaporator coil?
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 should be located on the evaporator case.
yes
No the out side fan is for venting heat away fromt he unit.
A motor can seperately power a fan that blows either in a forward movement or reverse movement. The air can be projected towards a direction with blades/rudders. The combination of both a fan blowing towards the ground (creating lift), and an upright fan blowing to create movement can make a hovercraft "go"
Without seeing the unit it`s hard to say with absolute certainty but most are air out.
During the defrost cycle of a forced draft low temperature evaporator, the evaporator fan would typically be turned off to prevent warm air from interfering with the defrost process and to help the coil achieve proper defrosting temperatures.
There are a number of reasons why your body aches after the fan was blowing on you. It could have tightened your muscles.
