Peace be upon you As is clear, the Hitachi refrigerator has a problem where the refrigerator does not cool, but the freezer cools very well. A technician came and said it needs refrigerant and a new door seal for the refrigerator, but I didn't do it because I bought a smaller one. As for the oven, it needs cleaning and lubrication, and everything in it is working, God willing. And peace be upon you.
