Question about Refrigerators
Below the evaporator fan is the evaporator coils. Remove the
back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL)
or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR
The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.
check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.
You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

It sounds like a problem with the defrost system that had gone worse in time.
If defrost fan was not working then the fan should have been tested by energizing fan motor. If fan was working, then test the defrost thermostat that start the fan. If fan motor was blown , you should have replaced the fan with original replacement, not with an external fan.
The situation surely put under stress the compressor motor. Probably now the compressor is gone too.
Try defrosting completely the fridge, by leaving it disconnected for two days. If when you restart the fridge, you find that it is cooling again, then it is still defrost system. In this case the fridge will stop cooling after a couple of days or weeks. If it still does not cool at all, check the compressor.
