Refrigerator not cold enough

For the same reason you want them at different temps.
Older single controls would affect both temperatures. So if you wanted the ice cream to be a little softer, the milk spoiled. If you wanted the meat to stay frozen longer, the lettuce got iced.

Am surprised your refrigerator is 'blowing hot and cold thru the same mouth!. Try turning the power off and keep the doors be open for 12 hrs. Wipe off water under the fridge and turn on power.Good luck.

Ice cream will get hard when the temperature is closer to - 20 C or -1 F scale. Water becomes Ice at 0 C or 32 F scale.

Ice cream soft means your freezer is not cooling enough.

You were cleaning the coils? Both condenser and evaporator coils? Cleaning coils and then loosing cooling in the fridge is not a good sign or combination. May be there is a freon leak and the seal system is low on freon now.

Call a service tech to check the seal system.

Unfortunately, if it is a leak you may eventually buy a new fridge after spending money on freon fill up, freon system sealant, leak check etc etc... No good news. Sorry

How old is the fridge? Most units have a system of tubing attached to metal fins, which is located in the back of the unit. This tubing & fins must be kept clean as dust will accumelate & insulate the freon gas from turning into a liquid.. Another problem is when the motor & compressor does NOT get enough air to cool the tubing & fins. This happens when the refrigerator is located in a closet type atmosphere where the unit is too big to get any air to the rear of the unit. NO spacing on the sides or top. ALSO, the compressor might of died. In this case, if the unit is out of warranty and/or over 7-15 years old, buy another, NOT worth the repair. If still under warranty, call vendor/manufacture.

If the upper compartment, the freezer part is open on the ends and the rest of the refrigerator is cold enough, that can't be fixed. If the the box is closed on the ends seperate, check the flow control of air if it has one, check the thermostat and set it till things nearly freeze in the lower non frozen section. If all this doesn't work and you can't keep the ice cream turning to milk, gotta get a new refrigerator.

Check under the fridge to assure the coils are clean, if not vacuum and clean with a brush accordingly. While you're down there, make sure the condenser fan motor is turning. Check inside the freezer compartment to make sure the evaperator fan is running.

Your refrig is under warranty . I would suggest calling an authorized warranty repair company .

If, the fresh food section is 34- 38 degrees, then the freezer should be cold enough to keep ice cream solid. All of the cooling capability comes from the freezer section. I, personally, would not waste time or money on a ten year old box. Ten years ago it cost $1000, so, the outlay is $100 per year. Dump the old refrigerator and get a new one.

Defrost is bad.Check the defrost timer,defrost element ,and defrost thermostat

Icecream is a tough call. Some brands have to many artaficial ingredients and that doesnt get solid. What temps are you getting in the freezer? Is everything else frozen solid?
