Where can I adjust thermostat on Danny fridge

raise the thermostat setting to 4 ( 1 is near zero c)
if it still does it have the thermostat replaced

There is normally an adjustment knob inside the fridge, in the back or top to allow you to adjust the coldness. Numbered 1-9.
If you have already adjusted that it would help if I know the type (side by side, freezer on top or below) and the brand. Most side by sides blow some of the air from the freezer side into the fridge side with internal fans and vents. How is the freezer side coldness knob adjusted?
I would set both knobs to 5 and go get yourself a outdoor thermometer to put in each side. It should be about 35 in the fridge and about zero in the freezer. Remember it will be warmer in the top and colder in the bottom of each.
Was the thermostat you replaced in the freezer or fridge?

You've indicated that you have changed the thermostat but the model number you have given is electronically controlled via an NTC. If the the unit is built in there is a possibility that one of the following is causing the problem
a. the seal is no longer catching properly because the decor door needs adjusting.
b. the internal lamp is not switching off when door closes and is creating heat that the fridge is trying to compensate for
or
c. the fridge fan is not operating and not circulating the air to the sensor. (You can check the fan and light by pressing the switch at the top of the fridge compartment frame, the fan should run and the lamp go off when the button is pressed).
Try these first and repost if this does not help.

Try the thermostat on it's lowest setting first. If it doesn't switch off soon enough and gets too cold, you can get different thermostats from your supplier. A bottle fridge thermostat would suit.

You will need to adjust the thermostat.
The thermostat will be hidden at the bottom back of the fridge near the compressor.
You may need a screw a flat blade driver driver to adjust the themostat

adjust the thermostat setting if digital type thermostat adjust it by pressing upward if your thermostat analog type rotate it counter clockwise then observe operation of thermostat. or replace thermostat maybe it is already damage.

Either the thermostat is set to high or you need to replace the thermostat.adjust it to 1/2 way position position and if temp is to cold and it doesnt want to switch off, it means the thermostat is faulty.

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. 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.

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.
