Understanding the Problem
When your refrigerator is set to a normal temperature but everything inside is turning to ice, something is preventing the cooling system from regulating properly. The fridge is overcooling because it does not know when to stop. This is usually caused by a faulty thermostat, a defective thermistor (temperature sensor), or a malfunctioning temperature control board. These parts are responsible for reading the internal temperature and telling the compressor when to turn on and off.

Helpful Repair Tip
Start by checking your temperature setting — make sure it has not been accidentally bumped to the coldest position. If the setting is normal but food is still freezing, test the thermostat with a multimeter. Turn the thermostat from low to high — you should hear a click. If there is no click and no continuity, the thermostat needs to be replaced. Also check the thermistor with a multimeter — its resistance should change as the temperature changes.
