Is your fridge making a lot of noise?
Why is my refrigerator so loud?
There could be several reasons why your refrigerator is making loud noises from usual motor noises to possible problems with internal parts of the fridge.
Is your fridge making more noise than usual?
Check the Evaporator Fan
The evaporator fan is located at the back of the freezer. If the fan blade doesn’t move freely here, it might be necessary to replace this part.
Compressor
If it seems like the condenser fan functions as it should, there might be problems with the compressor. We recommend asking for professional help to diagnose the issue.
It's completely normal for your fridge to hum, however if you're concerned please consult your owner's manual or contact Bosch Customer Support at 1-800-944-2904 for troubleshooting assistance.
