It is relatively normal for the sides of a refrigerator to feel warm or slightly hot to the touch when it is first plugged in after waiting for 24 hours. There are a couple of reasons for this phenomenon:
Compressor and condenser operation: The compressor and condenser are critical components in a refrigerator's cooling system. When you first plug in the refrigerator, these components have to work harder initially to cool down the interior and reach the desired temperature. This increased workload can cause the sides of the fridge, particularly near the compressor and condenser, to feel warm.
Heat dissipation: Refrigerators generate heat while they are operating, and this heat needs to be dissipated to maintain the internal cooling. Usually, there are coils or fins on the back or bottom of the refrigerator that release this excess heat. When the fridge is new or recently plugged in, it might take some time for the cooling system to stabilize, and during this time, the sides might feel warmer than usual.
However, it's essential to note that there is a difference between warm sides and extremely hot sides. If the sides are too hot to touch or if you notice any burning smells or other unusual signs, it could indicate a problem with the refrigerator. In such cases, you should immediately unplug the fridge and contact the manufacturer or a qualified technician for assistance.
As the refrigerator continues to run and reaches its target temperature, the warmth on the sides should gradually reduce to a normal level. If you are concerned about the warmth or have any doubts about the fridge's operation, it's always best to consult the manufacturer's guidelines or contact their customer support for clarification.
