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.


  • Yes, remove the jelly. Refrigeration systems aren't really user-serviceable. It sounds like the compressor is failing. Please take the tour so you understand how this site works. We're not a discussion forum.

  • Maybe it's just a bad gasket? How do you know if the compressor is failing? Maybe it's failing because of the damn jelly? Commented Mar 6, 2019 at 19:07

  • What can I do to get most out of this compressor now? Commented Mar 6, 2019 at 19:11
  • Definitely remove the Vaseline/Jelly? Commented Mar 6, 2019 at 19:11

If it's "bubbling" while it's running it could indicate improper charge. A refrigerant system should have liquid at the metering device. If there is still vapour in the mixture(saturation temperature) then you are loosing capacity which would explain the long run times. It doesn't mean there is a leak it just means that it's not running at full capacity.

In this image the metering device is an expansion valve. enter image description herewww.wikipedia.com

It gets pretty complicated but to aid you in your search for the problem if something you try makes the bubbling sound go away you may be on the right track. Keep in mind any changes to system take about 15 minutes to stabilize. Sometimes just pulling the fridge away from the wall does the trick. With fridge has bubbling often indicates too much heat overall in the system.

  • Is it good to keep the refrigerator at warmer temperatures to keep the compressor running for more years? (and not fail) Commented Mar 6, 2019 at 20:00
  • Joe Fala so what do I need to do? Commented Mar 6, 2019 at 20:01

    The coil at the back needs to dissipate heat. I'd start by pulling the fridge out from the wall and see if it resolves.

  • Thanks. I always make sure there's a ton of room between the wall and the refrigerator coils! In total around 10cm Commented Mar 6, 2019 at 20:17
  • It could simply have a leak. But the things you have tried and pulling it out are free, so it's best to try them before replacing it. The fridge being too full restricting air flow inside usually would have the opposite effect but still worth a shot. Make sure the items inside are not all the way to the back of the fridge.
