Refrigerator is getting hot - what to do?


When a refrigerator is "overheating", this usually indicates that it is overloaded. What causes that can have, what you should always pay attention to, and what you can do to remedy the situation, you will learn in detail in this post.

Possible causes

The possible causes of a too hot becoming refrigerator can be very diverse. Possible are among others (use the following checklist):

checkedsource of error
#The fridge has to work too much because hot food has been put in the fridge
#the refrigerator door is leaking
#the fridge was left open
#The refrigerator is in an area with too high ambient temperature
#The refrigerator was tilted or transported incorrectly
#the fridge is installed with insufficient ventilation
Technician requiredthe thermostat is defective
Technician requiredthe compressor / heat exchanger is defective

Too warm food in the fridge

Under no circumstances should you put boiling or steaming food in the fridge to cool down. They must not exceed room temperature. Otherwise, the refrigerator is overloaded with the disposal of excessive heat. In addition, the steam can quickly form a lot of ice, which further reduces the cooling capacity.

Refrigerator door leaking

A leaking refrigerator door can cause heat to get into the fridge over and over again, causing the compressor to constantly work and overheating.

Refrigerator was left open

If a refrigerator is left open and then closed again, the compressor must cool the interior again with high power. Remedy: set the temperature to the highest level, and successively lower over the next few hours.

Refrigerator is in an area with too high ambient temperature

Refrigerators are only approved for certain climate classes and therefore ambient temperatures. If the ambient temperature is exceeded, the refrigerator must work too much. You may also want to look for sources of heat nearby.

Refrigerator was tilted or transported incorrectly

If the refrigerator has been tilted or transported horizontally, it may take a while for sufficient refrigerant to drain back into the compressor. If the compressor runs "empty", it can cause serious damage. The fridge is then usually irreparably broken. Always observe the notes on commissioning, the service life and the permissible mode of transport!

Refrigerator is installed with insufficient ventilation

The heat generated at the rear of the device (with built-in refrigerators below the door on the ventilation grille) must be able to be removed without hindrance. If this is not the case, the heat builds up and the refrigerator runs hot. It is therefore always important to ensure adequate ventilation. In addition, standing refrigerators may only be installed under the worktop if sufficient wall clearance and sufficiently large ventilation grids are available in the rear area.

Thermostat defective

Defects in the thermostat or corrosion on the thermostat sensor occur occasionally. Usually, however, they are easy and inexpensive to repair

Compressor / heat exchanger is defective

Damage to the compressor or the heat exchanger can usually only be repaired at great expense. Often a repair in such a case is no longer worthwhile. Damage to the controller may also be considered.

Tips & Tricks

If the refrigerator is overheating, you should immediately check the possible cause and turn off the refrigerator if it can not be remedied. Otherwise there is a risk of fire.
