Freezer is cold, refrigerator is warm.

The dial inside the fresh food compartment, the bottom compartment
set to middle or above (higher numbers mean colder). Usually 5 to 9 if it has numbers.

Freezer knob in the middle if it has one. (If you set a freezer knob to "colder" it cuts
off the cold air to the lower compartment). Hope this helps

a little door from freezer to fridge gets frosted shut. you need to defrost the freezer then run it on a medium temp not the coldest setting. also make sure to not over fill the wall in between the freezer and the refrigerator. (thats where the air crosses over) unlessp u have an over and under freezer refrige set up in which case your little door is in the floor of the top compartment and the roof of the bottom one. good luck

24 hours It should be good Do check temp settings.

Cleaned the condenser coils which were dusty but not severely so. Checked the evaporator coils which were NOT iced. Reset the fridge to coldest setting and freezer to #5 (mid range of temperature) and waited a full 36 hours. Fridge temp is 40 F and freezer is about 0F. Not sure what is different except coldest setting on fridge. Warm weather is here but not warm enough to require AC. Temps in late afternoon in house about 77-80F. Any thoughts are appreciated because I suspect this problem is not completely resolved.

I've made a mistake before with thinking that I was setting the adjustment correctly on a refrigerator before, sometimes those dials are hard to read if there is a graphic scale, or symbols etc. Instead of numbers with the highest number being the coldest setting. Anyway make sure the temp setting is set correctly, these are found in the refrigerator side.(yes even for the freezer, so it does'nt freeze up) I adjust mine all of the time, things only need to be so cold right.(helps my elect bill) Make sure those special compartments have clear air passages to them. best regards.

You have a defrost problem. Refrigerator gets cold via freezer. If blocked with frost, will restrict cold air into refrigerator.

You have a bad evaporator motor. It is located behind the panel in the freezer compartment. Fairly easy to replace.

depending on the temp it could
if the ambient temp get below 32
you freezer wont come on and actually begin to get warm (insulation factor)
but the refer will seem cold because of the low ambiant temp is the temp inside
we go in the refer alot more than the freezer

First, I think it’s important to know that the Ref side has no cooling coils, it’s basically a box and the cold air in the freezer is blown over by a fan through a channel into the Ref side. This channel has a door which regulates how much cold air goes through. You probably have two control knobs in the Ref side, one controls the temp with numbers 1-9, 9 being the coldest. This temp control tells the compressor how long to run. The other control is for that little door and it may have letters A-E, E being the coldest. If you set it on E (coldest) then this will close that little door and keep most the cold air in the freezer.
So, how can the Ref side be cold and the freezer side not freezing?

1. Coolant leak. There is enough coolant to keep the Ref side cool but not enough to freeze on the freezer side.

2. Defrost system failure. The coils on the freezer side are clogged with ice and it's just a matter of time when the Ref side won't cool either. The back wall in the freezer will be covered with ice/frost

Check make sure evapurator fan is blowing and nothing blocking any return vents in refrigeratro side prevent air from recirclating
