Analysis of the main reasons for mica at the outlet of the furnace is heated by microwave process food ( especially oily food ) smoke heavily polluted , causing the insulation resistance is lowered , under the effect of microwave heating burning smoke. This has become a new conductor fumes fork , so that the export of microwave magnetron ignition occurs , even when serious damage to the magnetron antenna , and sometimes high-voltage fuse blown .dBxservice manual download site

Repair method is very simple , unplug the furnace within the four corners of the fixed mica plastic clips ( some microwave ovens, such as Galanz oven mica waveguide is vertically inserted in the mouth ) . Remove mica, dipped in ethanol with oil paints carefully cleaned, and then use the hair dryer to dry. Since both fumes into the waveguide cavity magnetrons and magnetron seals on the transmitting antenna and so these parts should be carefully cleaned with ethanol and drying , the final recovery , fault that can be quickly ruled out.
