Hello Cuba, here also Cuba, but from where I write. Nothing just to take care that the doors of your refrigerator, hermeticen well, especially in the joints of the door weatherstrips, that the same rubber can be in poor condition. You should also take care because it is so hot for that beautiful Buenos Aires, that the equipment is located in a dry and ventilated place, that allows you to do your functions well. You should also check, the thermostat or temperature control, that the same for this intense summer, its regulation knob is not located, in a very high regulation, for more cold and this makes the compressor just make its routine stops , to eliminate, in each stop that it carries out, all the frost formed in the bottom wall of the refrigerator, in that evaporator plate that it carries in the conservation or maintenance compartment. That area should only maintain a slight frost that never exceeds a thickness or thickness of said frost or ice greater than 1 centimeter thick, since from there, the team would lose the logical exchange of heat with products or food stored inside that conservation zone, causing for that reason a total loss of cold and therefore the possible deterioration of stored food. In case everything is correct, but still the thermostat continues without stopping the compressor even by placing its regulating knob in a minimum position for less cold, in that case, you should with a product loosen everything like the WD-40, to make a maintenance of the thermostat, so that this, product of the humidity and the conditions in which it works, loses the rigidity, that it may have reached with the operating time and recovers, its functions or otherwise procure a new thermostat, to replace the old one, but with the same technical characteristics, of the old thermostat itself.
