The thermostat is an integral part of your refrigerator that regulates the temperature of your appliance. If the thermostat doesn’t work, then your food could spoil.

Signs Your Refrigerator Thermostat Isn’t Working

If you notice temperature fluctuations, the most common culprit is a malfunctioning thermostat because that is the part of the refrigerator that regulates the internal temperature of the appliance. Here are some of the most common scenarios of a broken thermostat.

Temperature Doesn’t Change When Altering Thermostat

If you notice the temperature in your fridge is too hot or too cold, the first step is to adjust the thermostat. 

However, if you notice no temperature change despite adjusting the thermostat, that means the thermostat has lost control over the fridge’s temperature.

Refrigerator Isn’t Cold Enough

The fridge relies on a thermostat to make the appliance’s temperature cold enough to store food. If your fridge is too warm, that’s a sure sign that the thermostat isn’t working as it should. Try putting a thermometer inside the fridge to record the actual temperature.

Refrigerator Is Too Cold

Most people know that a warm fridge is a problem, but if your refrigerator is too cold, that’s another common sign that the thermostat is malfunctioning. Check your thermostat if you notice food freezing or frost forming inside the fridge.


If you notice any temperature fluctuations in your fridge, such as the appliance becoming too hot or too cold, then its likely a sign that your thermostat isn’t working. Try adjusting or resetting it; if the problem persists, call a professional.
