The cold control thermostat with a meter for both OHMS and volts ( VOLTS is a live test with fridge plugged in so be careful) It must show 110 volts. An open or thermostat that reads infinity will not allow the proper cooling and defrosting cycles to operate and may in fact stop anything from happening as if there is no power to the unit?
ALSO CHECK THE AIR FLOW VENT SYSTEM and THERMISTORS At times it can get stuck to far closed or open. Some units feature a digital electric adjusting vent system while others are manually set. Check for any ice build up or other obstruction in the vent damper, see if u can manually open or close it. Some times when u have the settings set to the highest it closes off one area while allowing to much cold air flow to the other area!
THERMISTORS in the freezer and fridge section for continuity OHMS and for amount of OHMS current being put out. In most models around 1300 ( give or take 150 ohms) ohms is required

your sure the defrost cycle works? sounds to me its not. you need to remove the freezer back and check the defrost components. or put it in the defrost cycle and see if it is working. to get that much frost as you describe the dor would have to be left open. also check all door seals. let me know what you find and we can go from there

Sounds like a defrost problem. Check to see if
there is any frost buildup in the back wall of the freezer. If so, it is not
defrosting as it should.
If
you don’t know what these are then unplug the machine and let the ice melt in
the freezer overnight with the door open. Then try it the next day, if is
cooling fine then you need to have a service person replace one of the above
items. If it still has a problem then it might be the compressor and you should
probably replace the machine.

too much ice bulid up will stop enough cold air being blown into the fridge.Try turning it off letting all ice melt then turn it back on again and set thermostat at a lower temp.There may be ice you can't see.
Check the compressor and the relay. Make sure they are working when you turn on freezer and fridge to the max. If the compressor does not start then you need a new relay. If the compressor starts then it is your thermostat that has gone bad and must be replaced. you can find the parts on repairclinic.com and order them with instructions on how to remove the bad part and install the new part
