Hi guys, I have a small refrigerator, with a freezer, no frying, no cutting, I changed the cold level with the knob and nothing. Will it be the thermostat or something like that? I don't understand very much, I appreciate your help.

Most likely, it is the thermostat that is failing the ideal is to change it or if you are not very suitable, buy a clock timer and program it to your own liking Regards

Do not place timer by thermostat change thermostat and luck tests

Remove the thermostat and take it as a sample to a house of spare parts for household appliances, then as well as you removed or disassembled it, so you put it back, greetings and good luck with that.
