Good morning, I have a problem with my refrigerator and I need help trying to repair it. Since the end of April it does not work properly. It is that moment it "blocked" freezing the evaporator of the freezer and I discovered it because the fan had begun to make a loud noise. Previously noises were heard as if they were explosions. I took out the resistance and I could see that it was cut, so I replaced it with a new one. From that moment on, the evaporator did not freeze (I left it unplugged for two days after changing the resistance), but it began to frost on the freezer, something that had never happened. And along with this, the cold passage to the lower compartment was covered again. Then I changed both bimelates (I put the originals) and after a couple of weeks it stopped going cold again and produces frost again. Can you guide me on how to solve it? Could it be that the platelet is failing? From already thank you very much. Regards
