Bosch Microwave Making Loud Noise
Microwave Making Loud Noise is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
Scale on a component that was never meant to carry it
On the groundwater end of this valley, deposit on a pump impeller or fan hub unbalances it, and the noise arrives long before the part actually fails.
A failing fan motor
Evaporator or condenser fan bearings wear out gradually, producing noise well before the fan actually stops running.
Loose or vibrating panels
Cabinet panels or compressor mounts that have loosened over time can resonate against nearby surfaces.
