Clean the condensor coils under the refrigerator with a coil brush,there are usually two knobs with numbers in the refrigerator compartment,the one to the right is the thermostat,turn that to number 5 the one on the left control a shutter that let different amouts of cold air into the refrigerator,turn it to number 2,the lower the number the more air will be allowed into the refrigerator,wait 24 hours for the temperature to stabilize,after 24 hours if the temperature is not perfect in the refrigerator and the freezer check to make sure both evaporator and condensor fan motors are working ok,if they are both working ok the problem is a weak compressor.
