A microwave oven is a useful household appliance serving to warm up, cook and defrost food. And like any technique, the microwave oven is prone to breakdowns. But, what if suddenly you notice that a microwave is sparking? This situation, by the way, is not uncommon. Therefore, we will talk about the causes of arcing and what to do in such cases.
The main reasons why a microwave spark
Sometimes the appearance of a spark in the working chamber of the device during operation is due to the fact that there is something metallic inside: a plate with sputtering, a spoon or a fork. But most often the microwave sparkles because of contamination and burnt mica plate-scatterer. It covers the magnetron inside the device from the working chamber. With frequent use on mica begin to accumulate food and fat. Pollution with repeated heating burns mica gasket. As a result, the plate conducts current when the device is turned on and sparks.
Often the reason that the microwave inside sparks can be damaged by the enamel of the working chamber. This leads to a strong contamination of the walls with grease and stains of food and the lack of timely cleaning of the device.
What if the microwave sparks?
If there is a frightening spark inside the microwave oven, the first thing to do is not panic, but turn off the power of the device. Then open the appliance door and make sure that nothing metallic is visible inside the camera.
If the reason is not this, then do not worry, thinking that the microwave has broken down. Most likely, the problem lies in burning mica or damaging the enamel. In any case, use the microwave oven is not necessary - it should be carried to the service center, where for a small fee will restore the enamel or change the mica gasket. Otherwise, the work of the magnetron will be disrupted, but its replacement is not cheap.
The fact that the microwave works, but does not heat , also requires immediate correction.
