Microwave oven: choice of the furnace and repair of microwave ovens with their own hands

UHF long it has been an integral part of the kitchen interior. They allow you a few minutes to prepare a delicious pizza, heat or bake croissants for breakfast sandwiches with cheese. Like any other electronic device, they differ in price, functionality and design. There are low-end models, capable of performing a few simple operations, and there are also professional multi-function units that can create culinary masterpieces.

control type

The main characteristic that influences the choice of the microwave - this type of control: mechanical or electronic. Each of these two types there are pluses and minuses.

Mechanical - the most simple and familiar to use. It consists of two arms, one of which is responsible for the power and the other for cooking duration. The main advantage of this type of control - a small price, and ease of handling. Such microwave very often buy the elderly, which would be difficult to understand all the wisdoms of the dashboard. In models with mechanical control to warm bowl of soup, enough to slightly rotate a knob. You can also note the high reliability of the mechanics, repair it needs very rare.

Of the minuses can be noted the complexity of accurate billing time. For example, it can be set to 40 seconds, 1.2 minutes and 6 minutes on an electronic panel. Mechanical handle time is set approximately, by eye. In this case it is easy to overheat the products requiring precision exhibiting, for example, baby food.

Before you opt for any particular model with mechanical control, it is necessary to pay attention to the timeline next to the handle. Some budget microwave ovens, for example, Supra MWS-1814 range comes in increments of five minutes, intermediate values ​​are not marked. One, two minutes have vymeryat estimated, and it is not always convenient.

Electronic control more modern. It allows you to set the cooking time up to 10, and in some models to 1 second.

As a rule, in addition to the control panel buttons "Power" and "Minutes" has a whole set of additional programs such as defrosting by product type, cooking dumplings, pizzas, cereals, French and Italian kitchen. The more expensive the microwave oven, the greater their programs, the greater their chances.

For models with electronic control is necessary to pay attention to the presence function "Quick Start".

This little button is convenient because it reduces the number of clicks and simplifies management by automatically launching the microwave at work for 30 seconds. Each successive press adds another half a minute. For comparison, to expose 1.5 minutes on models without this feature, you need to select 1 minute, three times for 10 seconds and press the start button. 5 presses against turns 3.

volume

Modern microwave oven volume is 17 to 30 liters. small microwave suitable for a small family, in which the products are reheated midstream. The model has a capacity of 20-21 liters can be placed thawed whole chicken or a large plate of food at the 3, 4 people. Microwave 30 liters are often used as a professional in a cafe or dining room, they are bought in large families and are most often used not only for heating but also for cooking.

Type of coating within the chamber

4 is separated form the furnace cover:

• enamel;
• bioceramic enamel;
• ceramics;
• stainless steel.

The enamel is most often used in inexpensive models, this is the easiest and a budget option. Bioceramics or ceramics are slightly more expensive, but from a practical point of view is necessary to stop the choice on them.

They are easier to clean and more durable, do not cleave and covered with cracks from high temperatures. Some manufacturers, for example, the Samsung offer 10 year warranty on their coverage of bioceramics. If we consider that the repair of the surface is not possible, and to operate the microwave with a damaged enamel can not, you should opt for a more durable version. On sale you can find a microwave oven with an internal chamber, decorated with stainless steel. Typically, such models are expensive enough as stainless steel material itself is not cheap. Advantages of such coatings are obvious: it does not skoletsya not oblezet, will not crack, but it must be cleaned gently to avoid leaving streaks and scratches.

Power

Occasionally, when this factor dramatically affects the choice of the microwave, but some buyers pay attention to it. The standard models of the power ranges from 700 to 800 W if there is a microwave with a grill, it can reach up to 1000 watts. There are professional models of high power, for them, for example, could be considered Kuppersberg technique, but they belong to the premium class and have the appropriate price. Power affects the heating and cooking speed. The higher it is, the faster warm up soup or a cup of thawed chicken.

Grill

Perhaps this is the most important feature that influences the choice of the model and gives a lot of additional features. In fact, the microwave devices designed for heating, not for cooking. Penetrating the product, the microwaves heat the water inside, thereby raising its temperature. If a piece of chicken in the microwave for a long time to keep it dry up, not fried, because all the water will evaporate from it. Grill - is, in fact, the conventional heater, which is found in ovens and hotplates. It allows you not only to heat but also to fully cook in microwave ovens.

Are 2 grill type:

• Quartz - is in the form of quartz lamps, hidden in the top of the inner chamber and the closed protective grille. It is cheaper, more economical, but it heats evenly and more difficult to clean. You can also mention that the repair of the grill will be worth more.
• Heaters - is a standard-wire heater. Fairly easy to clean, in many models, it changes its position in space. There furnace with two heating elements, one of which is attached to the ceiling, and the other to the rear wall. This design makes it easier to bake to a turn three-dimensional products, such as a whole chicken.

It is worth noting that the presence of the grill significantly increases the cost of the microwave. Therefore, the buyer should stop your choice on models with this feature only if it is certain that will use it once in a while.

Inverter furnace and convection

Even five years ago, they easily can be purchased for 3-4 thousand rubles at any store appliances. Who inverter technology was only a few, mostly expensive models, Siemens, Bosch, Panasonic. That it gives to the consumer?

In conventional microwave ovens while reducing power decreases not the power and frequency switching device.

Simply put, if you turn the knob to 800 W up to 400 W, the microwave oven will heat to the same 800 watts, but with a long interval. Accordingly, in the mode of "defrosting" upper layers just overheat as on heating. Inverter as it reduces smoothly - 800 correspond to 800 W, 600 W and 600 correspond etc. When this product is thawed evenly without dries on the surface.

Professional microwave ovens for cooking and baking often go with a "convection". Built into the rear wall of the fan evenly distributes heat throughout the volume of the chamber. As a result, a piece of meat zapechotsya not only from above but also from the sides and bottom. This microwave oven can replace an oven.

Additional functions

In fact, their great variety: odor removal mode, the camera lights, express defrost and others. Focus only on the most popular and relevant paragraphs. They rarely have a decisive influence on the choice of the microwave, but can serve as a nice bonus.

• Child lock. By activating this function, the button will not respond to touch, and the child will not be able to change the program.
• Capacity for steaming. As typically a small cup with a double bottom which is filled with water. Allows you to cook for a couple of small meals are not only tasty, but also healthy food.
• Automatic cooking. Some models allow to cook some simple dishes such as porridge, dumplings or fish. Some offer a choice of more elaborate dishes of French and Russian cuisine. To prepare the food at this time, it is necessary to lay the ingredients, indicate their approximate weight and run the program. Microwave itself will select the optimum power and cooking time.
• uniform system of distribution of the microwaves. Some manufacturers design their models in such a way that the radiation sources have been 2 or 3, which allows uniformly from all directions to heat the product.

Rules microwave oven operation

In order not to have to carry a microwave in the service, to do repairs on their hands, or worse, throw it in the trash, it is necessary to operate the equipment properly:

• use only a glass, ceramic or other utensils, intended for microwave ovens. It should be no gold or silver finish. The metal can be used only in "Grill" mode, when there is no microwave, otherwise can cause arcing or the arc, resulting in a fire and as a result, repair a furnace;
• you can not use the oven with the door open;
• if the door is bent or broken glass in it is impossible to carry out repairs on their own;
• Do not dry cereals or cloth. There were cases that attempted in the microwave to warm salt in the linen bag to treat otitis media, which also resulted in a fire and repair;
• can not cover the ventilation slots to avoid overheating if they are placed on top, put on their plates, magazines, utensils.

For more complete information about the operation of the rules can be found in the instructions, which must be attached to each unit. Also included there is a list of service centers, where you can carry out repairs and diagnosis techniques.

Typical damage and repair

As a rule, small breakage, most buyers are able to correct their own hands, for example, to repair or replace mechanical regulator plug.

For more complex faults for repairs is better to turn to professional workshops, otherwise you can pick up a dose.

Most often, buyers are faced with mechanical damage equipment dented, ripped off the hinges, broken latches. Hinges and other accessories can be purchased in the company's service and replace their own, dismantling the door.
Failure may withdraw mica plate, if it is somehow damaged mechanically or long time to clean the grease residue. Repair in this case is quite simple - it should be replaced in the same type. It is impossible to insert instead of a plate glass, or cardboard, or a small failure will lead to more trouble.

Sometimes a cause for concern may be faulty high-voltage diode. In this case, the microwave did not work, but when trying to turn it emits a buzzing and humming. Repair at this breakdown should entrust the service center, which will diagnose, to ascertain the cause of faults and replace the diode.

One of the biggest failures - the failure of the magnetron. As a rule, this is one of the most expensive components in the machine, so the repairs can be impractical. However, some craftsmen with their hands rearrange magnetrons with models that were in use. By the way, before carrying broken microwave repair can remove the cover and look at the wiring. Sometimes it is possible to repair their own hands: it is necessary to solder one posting, detached from accidental jolt, and the technique will work again.

If the microwave has recently purchased and still on warranty, you do not need it to repair their own hands, or even just trying to remove the case. Any tampering, small scratches on the bolts, homemade solders will be grounds for denial of warranty. The organization is obliged to repair the equipment, and if you do not keep within the specified time period of 60 days - to replace the equipment on new.
