Mini fridge freezer cold but fridge warm - Danby (DAR604BLS) Refrigerator

All questions need full 'make model (what it is)' please.

Do you have a freezer at the top and a fridge below it? That box is just a cold air vent from the freezer. There is often a circulating fan in there, but it could be elsewhere.

The issue with a warm fridge and a cold freezer is that the defrost for the freezer has failed and the evaporator is a solid lump of ice and not passing chilled air, OR, the vent is boked with ice. The is a defrost timer and a heater element at the rear of the freezer back panel.

If the refrigerator freezer is cold but the refrigerator is warm, the defrost thermostat might be defective. Several times a day the defrost heater turns on for a few minutes to melt away any frost that may have accumulated on the evaporator coils.Mar 3, 2015

Why is my refrigerator not cooling? - Refrigerator - iFixit

Is there a fan inside the freezer compartment to direct cold air to the fridge? Check it's working. If not fanned, check rear wall of fridge. If not cold, unit may be short of gas.

I would guess you have just caused a build up of ice to block the air way, which normally takes cold air into the fridge. manually defrost (unplug and wait until the ice goes away) then restart and it should be fine

Sounds like one or more of ofvyour 3 defrost components have failed which are defrost heater , defrost thermostat, and defrost timer or board

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.

That can be very difficult to do with a mini refrigerator. There is just not enough separation between the freezer and the refrigerator.

You will likely just have to find a compromise setting and accept the results.

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.

sounds like you may have gotten a refridgerant leak causing a low charge condition. some refridgerators have a evaporator fan if this quit working it will cause it to freeze up .thus the freezer does not use a fan and it will still get cold
