The thermostat is the most important part of the refrigerator. Its task is to maintain the temperature and turn the compressor on and off. As a result, the temperature rises or falls as needed. Moreover, the thermostat is also a temperature regulator – we use it to set the level at which the temperature in the refrigerator should remain. Thus, the principle of operation is quite simple. This little device controls the entire refrigerator. Its failure means that the equipment will not work properly. However, this does not mean that it is unusable, replacing the damaged part should work.
How to identify problems with a thermostat?
Thermostat problems are easy to identify. First of all, if you see that your food is thawed, an unpleasant smell appears in the refrigerator, and the temperature controller does not respond, most likely the problem is in the thermostat. However, sometimes the appliance can over-freeze all the food in the refrigerator. Ice on the walls and shelves and frozen food are also possible causes of thermostat breakage.
The thermostat controls the switching on and off of the compressor, so if it works too rarely or too often, it is worth paying attention to. The problem can also be that the compressor turns on momentarily and stops after a few seconds. If you can’t hear it at all, the problem can be much more serious – it means you need to replace the compressor. However, this situation is quite rare, so you should start by replacing the thermostat yourself.
You can replace the thermostat yourself. This is not a big expense, and on many portals and sites that offer parts, you can find new factory thermostats from brands such as Amana, Whirlpool, Bosch, Samsung.
There are different thermostats for the refrigerator. To buy a suitable one, you need to follow the information provided in the instructions for household appliances or on the thermostat label. Many brands label them with the refrigerator model name. Prices depend on the manufacturer.

The thermostat is always associated with a knob or button for setting the temperature regime in the chamber. Depending on the refrigerator model, the thermostat can be installed:
