Question about Liebherr KGBN 3846 Premium BioFresh Bottom Freezer Refrigerator
It does sound like you have a low refrigerant gas problem - only way to be sure is get a service guy to check. If you notice particularly cold parts on the wall of the fridge or freezer, rather than the more even cooling that would be normal, then this is almost certainly the problem, and should be easily enough fixed by a qualified technician. The other possibilities are: The thermostat in the freezer could be faulty -hard to test without the right gear, but just check that the temperature adjustment knob for the freezer if it has a rotary one hasn't slipped on its shaft - this would give you a different temperature than the setting you have set. Check the freezer door seal/hinge and make sure it is sealing properly all around especially at the bottom - only a small gap can make a big difference Check the back of the unit is getting enough ventilation - it should get fairly hot normally but if the ventilation is restricted then the heat has nowhere to go and the freezer wont cool completely - if there is a lot of dust on the back then give it a gentle brush - the pipes are quite fragile so be gentle. If you havent defrosted the unit for a while, try that - leave it open and off at least overnight until there is no difference between the temperature inside and outside - sometimes small amounts of moisture in the refrigerant gas can freeze into crystals and block or partially block the gas system, once they defrost they should be dealt with further round the system by the filter/drier and hopefully will no longer be a problem Hope this helps :)
