It's a beko CRF4800. The coils get hot and it runs for 40 minutes straight, resting for around the same time. It makes quite a loud buzzing noise, I think something is up with the fridge. I've already tried:
Cleaning the refrigerator coils and compressor completely from dust
Unplugging and melting it for 12 hours
Adding a layer of petroleum jelly to the gaskets so it would insulate better and cold air couldn't go out
Is it OK to remove the Vaseline now?
It started just buzzing like insane and running for about 1h30min after I added that jug of water into the deep freezer like I was told it's supposed to decrease run time... The deep freezer doesn't get used in our house, so it just runs without a purpose. I was told that it's better than "cooling volumes of air"
It also makes a bubbly or a wave noise when it's running and seems like it's "breathing" for some time after the compressor stops running
The temperature setting is on the very warmest, it still cools the food like a normal fridge with that setting, which is awesome (6C max in the freezer) but it hums all the time.
