Possible reasons why a microwave oven sparks
The appearance of sparks inside the microwave oven chamber is always accompanied by additional signs. Appears There is a grinding sound, there is a burning smell, the microwave is cracking. Such malfunctions indicate the development of more serious problems.
If the microwave sparkles when you turn it on, then most likely the reason is:
- heating food in metal containers;
- failure of the mica plate;
- coupler malfunction;
- damage to the inner enamel;
- failure of the socket or plug of the appliance cord.
Each of the above reasons can lead to more serious consequences. If sparks appear inside the microwave oven body, immediate repair of the damage is recommended. To do this, you can contact a specialized center or repair it yourself at home.
Ban on metal
The prohibition on using metal utensils when heating food is stated in the instruction manual. Many people needlessly neglect this rule: metal can cause not only microwave malfunctions, but also a fire.
When using metal utensils, the microwaves generated by the magnetron do not penetrate the food. The reflection of wave particles from the surface of the dishes causes an increased discharge of electricity (the microwave sparks and shoots). This is the cause of malfunctions. To avoid damage, experts recommend using a line of dishes designed specifically for the microwave oven. Simple steps will help increase the life of your kitchen appliance.
Coupler malfunction
At first glance, the plastic coupler seems like an insignificant detail. But he is the one responsible for rotation of the plate and uniform heating of food during the period of use of the microwave oven. Irregular cleaning of the internal walls of the housing leads to the accumulation of grease and dirt on the surface of the coupler. When the mode starts, it may spark (even if the microwave is empty), and an unpleasant odor appears. They occur due to heating and melting of contaminants.
Replacing a coupler should be approached carefully: many devices differ significantly from each other. You must purchase a similar product. Rotation motor located at the bottom of the oven. Therefore, you need to place the device on its side on a soft surface. Carefully remove the cover. On most devices it is secured with 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 housing.Then we remove the coupler and replace it with a new one. After replacement, we carry out the necessary operations to secure the rotation motor and the protective cover.
Damage to enamel
The inner walls of the microwave oven are covered with special enamel. With prolonged use, the paint begins to bubble and peel off in places. In case of such a problem, it is not necessary to replace the device. Paint the walls of the microwave you can do it yourself. As a coating, you can choose: organic food colors. They do not emit harmful substances and safe for health.
Before painting, it is necessary to remove the enamel from the damaged areas. Afterwards, the coating area is treated with sandpaper and solvent. After cleaning and degreasing, you can begin painting. It is recommended to carry out the process in accordance with the instructions indicated on the packaging. The new coating will significantly increase the service life of the microwave oven.
Important: It is better to entrust the work of replacing a cord plug or socket to professionals. This will help avoid serious injury.
Replacing the mica plate
The most common cause of sparking inside a microwave oven is mica plate burnout. It protects the magnetron from food elements during cooking or reheating. In a state of malfunction, the part comes due to the accumulation of fat and carbon deposits on the mica area.
As a result of heating food debris, the walls of the mica begin to burn through, and the coating itself is destroyed. This results in sparks. If timely measures are not taken, this can lead to magnetron malfunction.
Repair work to replace the mica plate can be done with your own hands. How to do it? First you need to remove the failed plate. It is usually attached with one or two screws. They need to be unscrewed. Mica can be gently pick it up with something sharp (for example, a knife) for more convenient removal.
Old mica can be used as a stencil when cutting out new mica. You can also buy components in a specialized store. Price - no more than 300 rubles.
After removing the plate, the inner surfaces of the chamber must be carefully will cleanseb from other contaminants. A damp sponge is suitable for this. After cleaning the wall wipe dry.
Then we proceed to replacing the part. The new material is attached in a similar way. Care must be taken to ensure that the corners of the mica fit exactly into the grooves. After successful installation, the screws are screwed in.
Specialized salons and services offer their clients a wide range of services for replacing mica plates of any complexity. The cost of the work varies from 400 to 900 rubles.
Prevention measures
In order to avoid malfunctions and extend the life of the microwave oven, several measures can be taken.
Possible options:
- Avoid using metal utensils. For heating, it is better to use containers designed specifically for microwaves. Also suitable containers made of plastic, glass, porcelain.
- To avoid residues of grease and food particles on the walls of the device, it is recommended to cover with a lid. For example, the lids of plastic food storage containers are equipped with a special hole.
- Clean the inside surface after use. kitchen appliance from food debris. This will help avoid contamination of the mica plate and preserve the enamel.
Conclusion
A microwave oven is no less susceptible to negative factors than other kitchen appliances. The appearance of sparks and an unpleasant odor indicates urgent repairs. A little free time and simple preventative measures will help extend its service life.
