Work microwave it based on the effect of microwave electromagnetic radiation impacts on the water contained in the food. High frequency vibrations heat the water in the products placed in the working chamber of the device. The food is heated.
In the furnace body located:
- shields - protecting the user from the microwave radiation leakage;
- magnetron - generating in excess of the high-frequency wave;
- monitoring and control system.
The use of serviceable devices safely. They are four levels of quality control and testing for radiation leakage. The device provides safety certificates.

Functions of simple microwave ovens
defrosting
defrost is present in all ordinary microwave ovens. When using the automatic mode, processing product runs under control of a program embedded in the device.
Using the manual mode requires the installation of the radiation power and duration of the process.
Power usual defrosting is about 150 - 300 watts. Accelerated process requires 400-500 Watts.
heating up
The main function of a simple microwave oven - heating the finished food. When using the automatic mode, you must select the volume heated by the product and its appearance. All other payments will be made automatically.
Manual mode, as in the case defrosting requires personalization. Reheating of food occurs at a power in the range of 550 - 700 watts. to 700 W mode suitable for preparing products requiring relatively low cooking temperatures.
cooking
Cooking in a simple microwave oven, according to the course of action is similar to the warming. If the owner uses the automatic mode, the indicated dish and weight.
If you use the manual mode, it requires self-control capacity of the furnace and cooking time. Rapid preparation and processing of products requiring high temperature mode occurs when the radiation power of 800-900 watts.
How does a simple microwave oven
The size
When choosing, look at the size. It should leave enough space for other kitchen appliances.
The device is built in the kitchen furniture or placed on the kitchen table. Big machine is conveniently located on a special shelf.
For a family of 2-3 people is enough volume to 20 liters. Devices, is equipped with a working chamber volume above 20 liters and additional functions - do not apply to simple, complex in their device and are not implemented in a conventional kitchen.
Color and shape
Different models have different designs. With the simple microwave ovens combine its appearance and design, design of kitchen furniture and colors.
internal coating
The quality of the coating material and determines the ease of cleaning and durability.
Heat-resistant enamel - cheap, hygienic, it is easy to clean, has an attractive appearance. However, it is easily damaged during cleaning and during longer temperature loads. Suitable for devices running on heating, defrosting or cooking small portions of food.
Stainless steel - durable, it resists thermal loads. Such a coating resistant to impacts during purification but does not possess the grease repellent properties.
Ceramic or bioceramic - a coating of low thermal conductivity. Due to this property, defrosting and cooking food faster. This coating saves energy.
Ceramics - easy cleaning. It long retains attractive appearance, but fragile. Do not use abrasive cleaners when cleaning this cover. Overheating of the ceramic coating can result in the formation of microcracks. This damage reduces the service life of the microwave oven.
For proper operation of the ceramic coating for a long time maintains its properties. This increases the life of trouble-free operation of the furnace.
Control
mechanical or electronic controls are used in different models. Simple microwave ovens do not require a complex control system and mostly they are equipped with a mechanical control.
mechanical control - is designed as a rotary switch. They regulate the flow of power and exposure time. This type of control is reliable, it rarely breaks down, but it is inconvenient to clean.
electronic control - is designed as a push-button or touch switches. Sensor switches can be easily cleaned of dirt, have an attractive appearance. Elimination of the electronic control unit fault requires service call.
Electronic controls precisely controls cooking and allows you to: use a pre-programmed operating modes, cook meals laid in memory programs.
Additional functions
With the simple oven pay attention to additional features and evaluate their need. If the device is used for simple tasks - they are unnecessary.
- Grill - is intended for frying food. TANS grill, use for frying heating coil enclosed in a metal or quartz tube, can be mobile - evenly heats the food, and is fixed at the top.
- Bread - This feature allows you to prepare simple pastries. breadmakers inferior function as a specialized work art.
- Double boiler - cooking for a couple. This feature complicates the design and increases cost.
- steam cleaning - steam cleaning reduces the time and effort spent on cleaning.
- removal of odors - self-adaptation eliminates assembled in working chamber, smells. The function is required for sequential heating or cooking of several dishes.
Please note that additional functions increase the price. If only heating the food, or rare cooking small portions of food - requires minimal functionality with manual control and a small volume of the working chamber.
installation
Carefully read the user manual. The manual contains the information required for safe use. Appliances that use electricity for their work, set on a flat, stable surface.
Make sure that:
- cooking cabinet door is opened freely without encountering interference;
- access to the ventilation holes open - this will avoid overheating, prolong the lifespan;
- kitchen grid allows you to connect it to the high-power device;
- open access to the wires and the power outlet to which the device is connected - it increases its safe use;
- the appliance is installed so as to avoid moisture in the body, the power cable and power connections.
Remember, excess moisture can cause a short circuit, causing damage to the unit or personal injury.
For cleaning the microwave oven use specialized tools. While caring for the unit - unplug it from the wall outlet. Before heating or cooking, verify that your cookware is suitable for use it in the microwave.
malfunctions
The device turns on, but not warm. This fault occurs for several reasons. The easiest option - the high voltage fuse blown due to a breakdown of one of the two door latches. For repair is required to replace the latch and fuse, but usually will not work, because the high voltage to the microwave oven has a tension spring for quickly breaking the circuit.
No backlight when the door is opened and during operation. This fault requires the replacement of the illumination source or relay energizes it (fails in rare cases).
Not included. Check the supply voltage and the condition of the socket to which the unit is connected. Check the power cord. Check the integrity of the fuse of the microwave oven. Perhaps due to a power surge blown thermal fuse - located under the adhesive tape on the transformer located on the control board. Replace the fuse if necessary.
The device is buzzing, there was a smell of burning. In this case a check of the electronic components. If you do not repair skills, contact the service center. The drone is typically associated with a malfunction of the magnetron or the transformer (in this case, the transformer is not yet out of order).
The appearance of sparks inside the processing chamber. This fault causes damage to the insulating layer. Damage caused by: pollution, improper care of the machine, using glassware that was not intended for this type of vehicles. It requires replacement of the mica plate. Using the machine with a fault provokes damage the magnetron.
The destruction of enamel. This damage is caused by improper care or defects of the coating itself. Continued use of the machine resulting in damage to electronic components.
Management does not work. Breakage is corrected by replacing button unit or sensors. If you are using a simple device with mechanical control - possible contamination of the contacts, which correct cleaning and degreasing.
Stopped rotating stand for dishes. Faulty engine provides rotation. the replacement engine is required.
