Practical training on repair: microwave ovens, vacuum cleaners, multi cookers, air humidifiers, hand power tools.
На курсах по ремонту бытовой техники вы научитесь ремонтировать: микроволновки, парогенераторы, пылесосы, мультиварки, увлажнители воздуха. Обучающие курсы способствуют на практике освоить ремонт бытовой техники.
During training in the repair of microwave ovens, you will study in detail the composition and operation of the components.
The microwave is made up of:
Microwave oven device
During the appliance repair training, you will learn the sequence of operation of the microwave oven units. On the course you will learn the following:
Microwave board
On the course, you will study the common malfunctions of microwaves, and in practice, learn how to troubleshoot emerging breakdowns.
| Microwave malfunction | What will you learn |
| Pallet plate does not rotate | Replacing the sump motor |
| Breakdown of the gasket between the magnetron emitter (cap) and the heating chamber | Install a new gasket without damage |
| Breakage of limit switches | Repair or replacement of limit switches |
| Not warm | Replacing the HF fuse, magnetron and feed-through capacitances |
| Does not switch to heating mode with a working magnetron and fuse | Checking the output voltage on a 2000 Volt power transformer (observing TB) |
| Does not heat with serviceable elements of the power unit | Checking and replacing the high-voltage high-frequency fuse |
| Camera not illuminating | Replacing incandescent lamps |
| Sparks in the chamber during microwave operation | Elimination of poor quality camera contact |
| Timing mode does not turn on | Replacing or repairing the clockwork motor |
| Camera door won’t open | Replacing door latches |
| Microwave does not respond to pressing the keys of the touch keyboard | Repair and, if necessary, jam the touch keyboard |
| Severe overheating of the case during operation | Replacing the cooling fan motor |
Microwave failure
During microwave oven repair classes, you will learn how to read diagrams and understand the element base. When studying the circuitry of microwave ovens, it is important to consider two blocks:
Microwave diagram
You will learn how to diagnose common faults using a multimeter. In practice, learn:
Diagnostics of microwave ovens
Studying in courses at Bgacenter, you will learn:
Examine the electronic control circuit of the vacuum cleaner. The principle of power control of the electric motor. Consider the logic of the vacuum cleaner microcontroller. Learn how to change software using the PicKit3 programmer. Consider an optocoupler using a phototriac. Study the operation of the power regulator using a powerful triac.
Consider different types of electric motors, types of their mounting, methods of replacement during repairs.
Learn how to troubleshoot common vacuum cleaner problems:
Vacuum cleaner scheme
Studying in courses at Bgacenter, you will learn:
Consider the structural and schematic diagrams of multi cookers from different manufacturers
Learn how to diagnose and repair all types of multicooker power supplies:
Learn the principle of operation of the microcontroller, its power circuits, the relationship with peripheral devices
Learn how to troubleshoot the main malfunctions of multi cookers:
Multicooker repair
During training and subsequent repairs, it is necessary to follow the safety rules when working with a high-voltage supply voltage of the magnetron. Which comes from a high voltage transformer, reaches 2000 Volts, 50 Hz AC and is fed to a half-wave rectifier.
It is important to clean the inside of the chamber with chemicals.
Before starting diagnostics, it is necessary to discharge the high-voltage capacitor 0.95 uF at 2000 volts.
When soldering the elements of the primary power supply, observe the precautions for working with soldering equipment.
Labor protection in the repair of household appliances
Bgacenter is developing a program for the diagnosis and repair of robotic vacuum cleaners. It will be presented on the website in the Courses section, in the near future.
Diagnostics should begin with checking the health of the network cable and thermal fuse. You can learn further diagnostics and repairs during the training.
First, you need to make sure the parameters of the selected fuse. Secondly, check the protective elements of the electronic unit. We invite you to a course on repairing household appliances. Where we study in detail the repair of such malfunctions.
Yes, you can. The electronic system of the washing vacuum cleaner does not differ from the usual one. The main difference is in the design of the engine and the presence of a water supply system.
Diagnostics must begin with checking the health of the heating element. For these purposes, a multimeter is used in the ohmic continuity mode. It is also possible a malfunction of the control circuits of the heating element, as well as the failure of the microcontroller.
Can. To replace bearings, you need to know the algorithm for disassembling the motor and have a specialized puller for removing bearings.
You need to have a special tool for disassembling vacuum cleaners in such plastic cases. You can learn this in a home appliance repair course.
Refrigerator and freezer repair courses. 90% of the practice is filling the system with freon, replacing the evaporator, fans, sensors, dampers, seals, repairing control modules.
Learn to understand in detail the device and diagnostics of welding inverters. Practice testing and soldering IGBT transistors.
Training in the repair of washing machines and dishwashers. 85% of the practice of replacing the electric motor, sensors, firmware of the control module.
