We decided after many back and forth for this refrigerator here. Energy consumption and the advertising with 38 dB volume has us tempted to buy this device. Super Space, bottle holders, everything just as we need it. After delivery then came the terror. Refrigerator and what kind of a perfumed. Not the gurgle or the compressor, the fans gave a permanent well audible sound. We immediately ordered the Bosch customer service the next day. It was clear, the fan is faulty! Whereas you had to say, the fan runs just over 70% on the day, even without a compressor. Door, fan and also passes between the fan on without a compressor. In addition, we have a freezer "No Frost". So we know equipment with fans. The customer service was and what can I say, that would be normal! They're all so loud. He would have been with so many customers. The fans are all in order. We could not glauben.Zurückschicken it or let's see here was the question. So ever looked what one has to do it. Fan on and what comes to the fore, a Sunon 80x80x25mm with a voltage of 9 volts DC. I do not believe it. OK, he was decoupled with rubber in the bracket, but that's the problem. So a cheap fan. We have the fan replaced with a 80x80x25 be quiet! SilentWingsPURE 12V DC. What can I say, which is unhöhrbar. Inside and outside! The fridge is the loss of the warranty, we take into account. The Siemens or the other is always the same fan in it. Identical. This is not an invitation to replace the fan, only our experience and do on this device.
