Metal ban
The ban on the use of metal utensils when heating food is prescribed in the instruction manual. Many in vain neglect this rule: metal can provoke not only malfunctions of the microwave, but also a fire.
When using dishes made of metal, microwaves emitted by a magnetron do not penetrate food. The reflection of wave particles from the surface of the dishes causes an increased discharge of electricity (the microwave sparks and shoots). This causes malfunctions. To avoid damage, experts recommend using a line of dishes designed specifically for the microwave. Simple steps will help extend the life of the kitchen appliance.
Cupler malfunction
At first glance, the plastic cupler seems like a minor detail. But, it is he who is responsible for plate rotation and uniform heating of food during the use of the microwave oven. Irregular cleaning of the inner walls of the body leads to the accumulation of grease and dirt on the surface of the cupler. When you start the mode, it may sparkle (even if the microwave is empty), an unpleasant odor appears. They arise due to heating and melting of contaminants.
The replacement of the coupler should be approached deliberately: many devices differ significantly from each other. You must purchase a similar product. Rotation motor located at the bottom of the stove. Therefore, you need to put the device on its side on a soft surface. Carefully remove the cover. On most devices, it is mounted on one bolt.
The engine itself is also attached with two bolts. In the process of unscrewing It is recommended to use a magnetic screwdriver. This will prevent the bolts from falling into the body.

Important: It is better to entrust the work on replacing the plug or socket to professionals. This will prevent serious injury.
The most common cause of sparking inside a microwave oven is mica plate burnout. It protects the magnetron from food elements. at the time of cooking or heating. In a malfunctioning state, the part comes due to the accumulation of grease and soot in the mica area.
As a result of heating food residues, the walls of mica begin to burn out, and the coating itself is destroyed. This leads to sparks. In the absence of timely measures, this can lead to malfunction of the magnetron.
Do-it-yourself mica plate repair work. How to do it? First you need to remove the failed plate. Usually it is mounted on one or two screws. They must be unscrewed. Mica can gently pick up something sharp (e.g. a knife) for easier removal.
