Every home has a refrigerator today. This device cools and freezes foods and food, preserving them for a long time. Regardless of the model of the unit and the year of its manufacture, the owner of the equipment can face an unpleasant problem – an increase in temperature mode in the refrigerating chamber.


Most often, the reason that the temperature in the refrigerator increases is the improper use of the device by the user. However, there are a number of causes that are much more serious and require attention. About the six reasons why the temperature rises in the refrigerator, we will tell in the material.


Causes of temperature rise in the fridge compartment


  1. Improper operation of the appliance

It is not allowed to install the fridge in a room with poor ventilation and high air humidity. When choosing a location for your refrigerator, choose a dry, well-ventilated room, away from radiators, direct sunlight, and other heating objects.

The optimal temperature in the room where the device is installed ranges from +15 to +31 ° C. If it is too hot, the refrigerator will consume more electricity, but will not reach the set temperature level inside the chamber. If it is cold, the unit will not produce enough cold for freezing.


  1. Tightness is broken

If the door of the refrigerator is warped, warm outside air can enter the interior. Also, the airtightness is compromised if the door seals become harder over time and lose their elastic properties.

By replacing the seals, you will return the door to being airtight.


  1. Refrigerant (Freon) leakage

If the capillary tube is clogged, this will cause the refrigerant to leak from the cooling system. The condenser located in the back of the refrigerator will help you determine this factor. If it is cold – there is a leak.

Only a qualified refrigerator repair technician can fill the system with freon.


  1. The thermostat is defective.

The thermostat is responsible for determining the temperature readings inside the chamber. It closes or opens the circuit to reach the set parameters, as a result of which the motor compressor is turned on or off.

If the thermostat is defective, it must be replaced with a new one.


  1. Temperature sensor does not work

This problem applies to refrigerators that have electronic control. In such models, it is the temperature sensor that determines the temperature mode inside the chamber. From the sensor, the signals come to the control module. If the data says that the temperature is too high, the motor turns on and starts cooling the chamber, if it is low – the motor turns off.

If the sensor fails, the temperature in the refrigerator will rise. A specialist will help to diagnose and fix the breakdown.


  1. Evaporator defrost system failed

This breakdown is typical for models with No-Frost. Since there is no ice in such a refrigerator, then with a certain periodicity the defrost heating element turns on. It is responsible for melting the frost, which is formed on the evaporator. If the defrost system does not work, the evaporator is covered with ice. Over time, the ice blocks the ducts that carry the air that cools the compartment. This will cause the temperature in the refrigerator to rise.


The following items may break in the defrost system:

  • Defrost sensor;
  • The fuse;
  • heating elements;
  • Defrost timer.


For the exact determination of the defrosting system breakage, it is necessary to diagnose the defrosting system. Only an employee of the service center can perform it. After this, he will replace the damaged part.
