The upper chamber of the WHIRLPOOL W7X 82I OX is not cooling.

It's June outside and quite hot in the house. There is currently no air conditioner. In the WHIRLPOOL W7X 82I OX refrigerator, the upper compartment is not cooling. The products have started to spoil. The refrigerator is less than a year old. We are looking for the cause and if something is broken - we will call a technician. We start the search for the causes with the refrigerator's manual. I threw away the paper manual, so I downloaded it from the internet (online stores like Rozetka or Foxtrot usually add the manual to the product card). In the manual, we read the section 'Troubleshooting'. In my case, the manual for the WHIRLPOOL W7X 82I OX refrigerator had some general things that this particular model does not have. Like - "Clean the drainage hole in the vegetable compartment." But this model doesn't even have a drainage hole. However, the manual helps to understand that cold air flows into the upper compartment from the lower one. Theoretically, the holes could be blocked by food or clogged with ice. Visually inspecting these holes - I saw snow/ice. The grille is secured with 5 screws, so I unscrewed them to see if the holes for the cold air supply to the other compartment were indeed blocked. And yes - they were blocked. Do not try to remove this ice with a knife or something - there is a risk of damaging various tubes hidden under this snow.

So we simply defrost the refrigerator. It's also a good time to clean it ^_^ But what is the cause of this problem that the NoFrost froze? I'm not a technician, but judging by the information from the internet - high temperatures in the room and insufficient ventilation around the refrigerator can cause ice buildup in the NoFrost system. Of course, the problem could also be with various sensors responsible for the proper functioning of the system, or a clogged drainage. After defrosting and cleaning the refrigerator - I removed the dust from behind the refrigerator and positioned it so that air could circulate around it (before, on one side, there were cardboard storage items stuffed in, but this hindered air circulation). Do not neglect the rules for using the refrigerator - leave technical space for air. By the way, the refrigerator does not have a water drainage tray - the drainage hose drains water into an open container near the compressor, from which the water evaporates into the air. An interesting solution. We plug the refrigerator into the network. We wait 4-6 hours before loading it with products. That's all for now. If the refrigerator freezes the holes again in a short time - we will call a technician and look for the cause. But for now, everything seems to be working and the reason was high temperature and lack of air circulation around the refrigerator.

Even if the cause is something else - defrosting won't hurt, and it will only make the technician's job easier. And cleaning the refrigerator and throwing away old products won't hurt either :D
