But what a very pervasive is perceptible: the fan - this shewed a constant 300 Hz tone. Constant tones are usually perceived as disturbing, which is unfortunately the case with this device. This not only switches after each opening the refrigerator door for about 30 sec. A, but also in between minutes every now and then for an estimated 3. In 5m distance the hum even with running TV is still good to hear (at normal volume). (Fridge --5m -> I --2m -> TV)
As our 15 year old refrigerator gurgled even less, I take that device from significantly since these noise pollution is not to be found in the technical data for potential customers but can be quite entscheident.
It is incomprehensible to me that the manufacturer, this has let it go in the development. Emergency would you just need to install a more expensive fan - which could have been in there with a MSRP of 1049.00 already.
Too bad: No recommendation from us
