The upper compartment of the refrigerator does not cool, the temperature indicator is blinking. (...
I wanted to drink some milk, but it had gone sour. The upper refrigerator compartment is as hot as room temperature. And it smells bad. And the temperature indicator is blinking for some reason... I've pressed various buttons and unplugged it... it doesn't help. I've wiped it clean. It doesn't help either. It's good that the service center phone number is written on the refrigerator; you need to call them and call a technician.
Stop! Don't rush! This isn't a malfunction at all! You just need to service the refrigerator and everything will work again! I'll explain and show you everything in detail in this video, watch until the end.
