If the microwave makes noises while in use, it is harmless in most cases - but not always. Find out which sounds can indicate certain causes of damage and which sounds you need to react to here.
Types of noise
Crackling and crackling may occasionally occur in the microwave during operation. These are usually sounds that occur when food warms up. This is not avoidable, but not dangerous.
Noise from the device itself
If the device itself causes noises, such as a crackling, crackling or humming, there is usually a defect (defective solder joints, cable damage). This is especially true if these sounds are heard even when switched off (not in operation, but plugged).
The earliest possible repair is indicated here, as in some cases such damage can cause a high fire risk.
Noise with sparking or flashing
If there are sparks or flashes in the cooking chamber in addition to the noise, the appliance must be switched off immediately. Causes are common here:
- metal parts in the microwave
- aluminum foil
- metal-containing dishes (plate with gold rim) but also
- soiling that char and thus generate sparks
The cause should be eliminated immediately. If the flashing continues after that, no matter what foods are placed in which dishes, the microwave is likely to have a defect. It should be repaired immediately.
Crackling noise due to unsuitable dishes
If dishes in the microwave heats up (this may not be) it is not suitable. This too can cause crackling or crackling noises. To test, either use another harness, or place the dishes in the microwave for 20 - 30 seconds (no longer!) And watch for heat. If it is warm, it is not suitable and must not be used, it could suddenly explode.Tips & TricksAlso oil or frying fats must never be placed in the microwave.
