Let’s look at the first case! In it, there is nothing complicated, just try to use the appropriate cookware for the microwave oven. If you can not use specialized cookware, then use any cookware, except metal cookware and metal-coated. And do not use polyethylene and low-quality plastic. Try not to put in the microwave cups and plates with patterns and spraying. Cutlery, namely a spoon or fork should not be placed in the microwave with the food. If this cutlery gets inside the microwave oven, you will immediately see sparks and hear a crackling sound. Note: Based on the above, you need to conclude – remove metal devices from the microwave, and use them for warming up food utensils that do not contain any metal elements.
In the second case, if the enamel coating inside the chamber of the microwave is broken, it is enough to buy the appropriate enamel, and do, so to speak, a small renovation of the inner chamber of the device, especially in those places where the enamel is damaged. To be fair, we should note that the failure to regularly wash and care for the inside of the microwave oven leads to damage to the enamel coating of the chamber. Fat accumulates on the walls, grease spots are formed, and quite strong pollution of this kind is quite capable of damaging the enamel, which, in turn, during the operation of the microwave, usually contributes to the appearance of a spark.
Finally, the third reason is mica. The microwave has a mica plate that separates the microwave chamber space from the compartment where the magnetron is installed. So, the mica plate in the microwave is installed to prevent contamination of the high voltage magnetron. Mica is a dielectric, and is excellent at letting microwave radiation through, much like a window that lets in light, but does not let air and various objects into the room. It’s the same here.
If the mica plate is contaminated with grease, pieces of food, and the like, of course, the plate will overheat, sparks and cracking will occur, resulting in the plate breaking, cracking. If this process is started, then the plate will burn out and the magnetron, and it costs quite a lot, so it is better to prevent the situation from worsening, and just replace the broken mica plate in time. This will save not only time, but also money.
So, you discovered a broken mica plate. Two options are possible here. The first is to take the microwave to the service, where the plate will be replaced. The second is to fix the problem yourself by buying the mica, cutting out the plate, installing it in place of the broken one.
If you decide to replace the mica plate yourself, the first thing to do is to buy it. Mica is sold both on the Internet and in some electrical stores. If the mica you buy is slightly larger than your plate, you will just need to cut out a piece of the right size.
Take the broken plate out of the microwave, it can be secured with screws or latches. Apply the broken plate as a template to the mica you bought. Make a marking of the mica. Cut out the new part with a stationary cutter. You can drill holes or punch holes. Work the edges with fine sandpaper. The plate is ready.
Replacing the mica plate in the microwave
Having prepared the necessary part, install it in the microwave in place of the broken plate, having previously cleaned the place of installation from dirt. After installation, check the performance of the device, for example, try to heat a glass of water. If nothing now cracks, then the problem is solved.
If you decide to use the service, there is nothing wrong with it, professionals will do everything qualitatively and reliably. However, it is not always necessary to complicate everything, because sometimes the problem is easily and quickly solved with your own hands.
