Vacuum cleaner repair training

Studying in courses at Bgacenter, you will learn:

  • device, principle of operation, sequence of disassembly and assembly of vacuum cleaners from different manufacturers
  • the main components of which the vacuum cleaner consists: body, wire with a winder, motor, electronic control board, hose (mechanical and electronically controlled), brush, dust collector


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:

  • does not draw in air
  • does not develop power when turned on
  • when turned on, there is extraneous noise and vibration
  • does not turn on
  • strange smell when turned on
  • power regulator not working
  • does not wind the power cord
  • the vacuum cleaner turns on, but the motor does not start

Multicooker repair training

Studying in courses at Bgacenter, you will learn:

  • device, principle of operation and sequence of disassembly and assembly of multicookers
  • the main components of which the multicooker consists: thermal fuse, heating element, temperature sensors, control relay, touch control panel, system board


Consider the structural and schematic diagrams of multi cookers from different manufacturers

Learn how to diagnose and repair all types of multicooker power supplies:

  • analog type
  • impulse type
  • using a quenching capacitor


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:

  • does not turn on (malfunction of the power supply or microcontroller)
  • thermal fuse failure
  • does not heat the heating element, while all functions work properly
  • violation of the sequence of the work algorithm
  • after a short period of operation spontaneous switching off to standby mode
  • temperature sensors malfunction

Occupational Safety and Health

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.

Do you teach how to repair vacuum cleaner robots?

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.

The multicooker does not turn on, how to fix it?

Diagnostics should begin with checking the health of the network cable and thermal fuse. You can learn further diagnostics and repairs during the training.

My microwave is broken. I replaced the fuse and it blew. What to do?

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.

Will I be able to repair washing vacuum cleaners after completing a home appliance repair course?

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.

The multicooker works in all modes, but the pan does not heat up. What repairs need to be done?

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 the bearings on the vacuum cleaner motor be replaced?

Can. To replace bearings, you need to know the algorithm for disassembling the motor and have a specialized puller for removing bearings.

The cord from the vacuum cleaner broke off. How can I restore it if there are no screws for disassembly on the vacuum cleaner body?

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.
