Why does the microwave sparkle inside

As much as we would like, but no household appliance can work forever. So, over time, the microwave oven also fails. Breakage may be different: the device does not turn on on or off during work, low heat or not warm at all, the pan is not spinning, buttons do not work... Today we will focus on one of them and find out why inside the microwave it cracks, sparks and shoots.

What can cause sparks?

Microwave sparkles due to several reasons:

1. Inside the device placed a metal dish or container with a metal rim.
2. Burnt Mica Plate may also trigger sparks.
3. Due to metallic, silver or gold plating on the plates.
4. Mechanical damage to the enamel.

If your microwave oven sparkles and cracks, and also shoots, it means that you did not act in accordance with the instructions andWithout repair there is no longer enough. Consider that independent repair of the device without due knowledge, can be dangerous!

Determination of the cause and its elimination

Forbidden dishes

In a microwave oven, in no case should you put food on a heating plate in a metal dish or in plates with gold, silver or metal dusting. If we neglect this rule, then it will be distributed crackle in the microwave and the unit will start spark.

The fact is that while the appliance is in operation, an electric arc is formed between its metal parts and metal dishes, which cause the microwave to sparkle. Be careful when choosing dishes for your assistant!

If you did not follow, and metal utensils or flatware got into the camera, stop the operation of the microwave and remove all prohibited items. Sparking must stop.

Mica plate

One of the most common reasons why a microwave is cracking and sparking is burnout plate from mica, which is responsible for the dispersion of microwaves.

Due to the heating of dishes, fats settle on the plate. But untimely cleaning and improper care of the microwave only accelerates the process of accumulation of food debris on the plate, which can catch fire. Over time, the lens is destroyed.

For the normal functioning of the device, you need to identify in time the reason why your microwave is sparking, and immediately eliminate it. Otherwise you risk to harm main part of the device - magnetronwhich costs almost as much as the microwave oven itself.

What to do in this case? First you need to check the plate for serviceability.

The diffuser is broken and requires replacement in the event that the microwave starts to spark, emits a burning smell, and carbon deposits accumulate on its walls, near the mica plate.

Step by step instructions for replacing the plate:

1. The first thing you need to wash the camera microwave.
2. Often the acquired plate does not match the size of the old one. In this case, it is better to purchase a larger-sized part and trim it by attaching the old one to it. The edges of the new plate should be treated with sandpaper.
3. Make holes for mounting.
4. Before fixing the mica plate, you need to make sure that the magnetron cap is in good condition. In case of breakage, you need to replace it.
5. We fix the new plate with screws.

As you can see, it is not difficult to eliminate such a breakdown, the main thing is to follow the instructions clearly. After replacing the parts, you need to check how the microwave works, but you cannot do this with an empty camera!

Damage to the enamel inside the chamber

Sometimes you need to heat a large amount of food and to save time, we choose bigger dishes. During rotation, the plate slides, rubs and hits the walls of the microwave oven chamber. As a result, scratches on the enamel, which prevent the correct reflection of microwaves, are formed. And this, in turn, adversely affects the functioning of the magnetron, which (as already mentioned) is expensive. Therefore, when the slightest scratches on the enamel, they immediately need to paint over.

You can handle this yourself:

1. First need clean the camera from fat, sand the damaged areas with sandpaper and degrease them with a solvent.
2. Then apply a layer of primer and two or three layers of enamel. For this suitable food, refractory or electrically conductive enamel.
3. We are waiting for complete drying and check the device.

If after switching on the microwave did not spark and smoke, then you did everything right, and the device is ready to work again.

Waveguide cover

Most breakdowns occur due to late cleaning Devices from fatty deposits, which over time can catch fire. The antenna from the magnetron emits microwaves in the waveguide chamber, which is covered by a lid. Accumulated pollution on the cover of the waveguide will eventually burn, because it acts as a dielectric, which does not conduct electrical current. The fact is that fire is the so-called plasma, which can be a conductor, which can cause sparks and pops in the microwave.

Socket and plug device

Sometimes a microwave oven can spark only when it is turned on or off. The reason for this may be a faulty power outlet or plug. If the contacts are not flush with each other, then the current flow is unevenly distributed. This can lead to to short circuit or break the microwave.

To resolve the problem, you should inspect the cord for damage: kinks, breaks. If any is found, the cord must be replaced. The socket also requires replacement in case of detection of cracks, chips and scale.

How to extend the life of the microwave

In order for the microwave oven to serve you for many years, you need to periodically pay attention to it and follow the generally accepted rules:

1. Wash and clean from contamination.
2. Do not include an empty microwave.
3. Do not place metal dishes or metal coated plates inside the device.
4. Inspect the device for damage to the enamel.
5. In order not to splash fat, you need to cover the plates with food with a special cap.
6. Do not put large dishes in the microwave oven chamber, which can damage the enamel.

Devices, like people, require attention and care. Use a microwave right: only as intended and in accordance with the instructions. Then the device will please you with a long serviceable work.
