Microwave sparks and crackles inside: what to do and what is the problem

Strongly sparks and popping in a microwave oven can be for several reasons:

• violation of the enamel coating the inner surface of the chamber;
• burned dielectric plate - mica, which protects the magnetron;
• oven stands metal utensils or objects;
• Product uploaded little and unnecessary rays are reflected from the walls.

The main unit in a microwave oven - magnetron. He creates and produces workspace microwaves. By steam, grease and dirt it protects the insulator of mica. It passes the beams and delay the dirt on the surface and the reflected waves, which penetrate the magnetron.

Most often sparks inside the microwave oven side due to a blown mica, smeared with grease.

The plate is on the side and closes the radiator. After contact with the surface dirt, oil spray, it will burn in separate places and begins to squeak, sparks. If time does not correct the problem, a spark hits the magnetron, and it will burn. The cost of this node is up to 90% of the microwave oven.

Over time, the protective enamel dishes and wiped against overheating and cracking temperature difference. It covers the metal inside the oven. It occurs waves entering into the opened under defects metal, an electrical arc, spark oblong, wherein the flash can be seen.

For a small number of products some of the rays not absorbed, reflected from the walls, damaging the enamel and mica. Overheating occurs within the chamber.

If the dishes are too large, the enamel is erased, especially in the lower part. Plastic packages melt leaking and contaminating the surface plates and the bottom of the furnace.

Troubleshooting

The general scheme of the microwave oven is made up of several complex nodes. Correct equipment you can own. For this purpose it is necessary to replace the plate of mica and restore enamel.

Substitution plate

Plate covers positioned in the recess waveguide - the magnetron antenna. It is made from a strong and fine mica. It can be purchased ready-made, but it is easier to find a piece of material and cut yourself.

1. Disconnect the oven from the power supply.
2. Wash the inner surface of the stove.
3. Hook thin protective plate screwdriver. Pull out of the grooves.
4. Draw and cut out the contours of a new piece of mica plate. It is not as elastic as established by the manufacturer. Protrusions included in the grooves, cut in 1 mm.
5. Unscrew the screws and remove the rear casing by sliding it backwards.
6. Discharge the capacitor. It is located at the bottom and can store a stored charge. Enough to touch the contact body and a wire or a screwdriver.
7. 4 unscrew screws holding the magnetron.

Remove assembly and test cap from chamber. It protects the antenna has the form of a cylinder with a hole in the bottom. Replace with the same purchased at a service center.

Assemble in reverse order. The plate was carefully put - it is fragile. First washed recess underneath. Then infest two distant protrusion into the grooves, then proximal.

Enamel and coupler plates

When the microwave oven cleaned and disassembled, remove the plate - spinning disk and coupler underneath - trenozhka, which is inserted into grooves in the bottom, and transmits the rotation of the motor. It now remains to closely inspect the surface and restore coverage for defective locations:

1. Buy a special tool - the enamel for the kitchen equipment.
2. Smooth out small skin imperfections.
3. Remove the dust with a vacuum cleaner.
4. Apply the product according to instructions and allow to dry.

Manufacturers offer many different enamels. Look to fit it for the microwave, if the primer and what is needed. Do all the instructions.

Check the coupler plate. If the disc black, it is necessary to crush. Deformed coupler replaced.

helpful hints

Do not operate the oven empty. Rays will not be absorbed. Reflected from the walls, the beams cover a harmful effect on entering the coating cracks begin to flash.

When heating to tea muffin, croissant morning coffee, put in a microwave oven dish or a glass of water. The stove will be more products, absorbing waves, and it will not shoot beams free.

First disassemble the oven, then with a mica plate, coupler cap and go to the store. Previous plate must be placed in the furnace with all the projections. It can be cut with scissors and knife construction. At the opening of the cap may be a different shape, the main thing - the diameter and height.

Coupler in the microwave "Samsung" different from all the others. He stops under the sole plate wider. On the model of all other manufacturers are set the same.

Prevention of faults

After prolonged use of microwave ovens allow it to cool.

Proper care and maintenance in accordance with the instructions will prolong the life of the microwave oven:

• regularly strangles internal surfaces;
• use of glass and crockery
• make sure that the camera does not permit foreign objects;
• grill used for baking only;
• not close tightly cover;
• not to large capacity which, when rubbed on the rotation surface of the chamber;
• foil, covering products, should have openings in the region of more than 2 cm from the edge of the plates;
• not to put to cook in the camera eggs and nuts.

Washing out of the furnace chamber, inspect the enamel. The cracks and chips in the coating open metal housing and cause sparking and crackling.

Form for roasting meat is desirable to stack or lay products in deep bowl to fat is not splashed to the walls and a protective mica plate.

microwave lasts for years with careful handling. If you start to spark, quietly take out the cause and repair themselves.
