Hello, I have a non-frost refrigerator brand Whirlpool model WRW5 1x1 which freezes behind the lid of the frezeer and stops cooling down. I disconnect it, let it defrost it, reconnect it and it goes well for 6 or 7 days that begins with the problem again, the lights on the display sound the alarm sounds and it starts to cool less in the lower part.- I changed the two sensors and the hot melt, the fan is perfect, the resistance was tested directly and heats well, the drain pipe is uncovered and discharges well, the engine starts and for normal, lack of gas does not seem to me because it cools well for A few days until it is covered with ice. I ask: could it be the plate that is behind the engine inside a plastic box? I think it's the only thing left for me to try or change.- IMG_20171223_101841472.jpg [1.26MB] IMG_20180202_075326393.jpg [1.97MB] IMG_20180202_105611778 (!). Jpg [3.91MB] These photos are the first with the data of the refrigerator, the second as it freezes behind the lid and the third with red marked the sensors that change and in blue the fuse.- I hope help.- Thank you very much. A hug.- Gustavo

Good night, if there is no other fuse inside the freezer and you already changed the sensors and everything, most likely the electronic card is not emitting the signal to turn on the resistance.
