If the fan isn't running neither section will be cold enough. There may be something jammed against the fan blade or the motor could be defective.

assuming fan now working. clean out vents/ drain holes (make sure no ice in bottom of freezer or in fridge unit)i.e. a total defrost.then check door seals all okay(no air leaks) if unit was trying to defrost itself and you reset to colder it will need to reset itself.....

Your automatic defroster coil is open and needs to be replaced along with the fan in the freezer that blows the cold air around and also blows air into refrigerator.

Bad smell down below is food rotting in that section because it is not cold enough.

Adjust the knob to 3 or 4 which would be the midway temperature.

0 would probably be off or close to it. The 7 would be coldest and freeze water.

If this is manual defrost you need to turn it off and defrost it. The frost will keep it from getting cold enough. The buildup is normal from humid warm air when opening the door. You might get a standalone fridge / freezer thermometer (about $5) to tell you what temperature is. The smell may be food spoiling from warm temperature.

hi! theres no funny when you smell burning please switch off the power and you che

try taking the bottom panel off and vacuming all the dust on the coils. The dust may be heating up and burning. The coils are usually at the bottom of the fridge. Check to see if the fan is running also.

Thre is a fan inside the freezer which circulates the cold air around both the fridge and the freezer compartments.
You should be able to feel cold air blowing around the inside, particularly at the top of the freezer.
If the defrost thermostat fails open, the internal fan (depending on freezer) will stop and this can be the cause of the freezer being warm at the top and no ice.
You say the bottom of the freezer is blowing cold, but are you sure its blowing, as it can feel like a cold blow. Of course the fan could have failed or may be the defrost heater itself.

Evaporator fan motor and main Pcb , the fan motor goes faulty and then burns out a resistor on the main pcb at the back.

I believe that you might have a coolant leak causing the chemical odor. You really should get it checked out by a fridge repair-person because it's not healthy to breathe in the fumes.
