A Fault In A Working Vacuum Cleaner Repaired
A vacuum cleaner was brought by a customer for repair. He said that it was working fine but the lever that controls the speed of the motor is faulty.
It is a vacuum cleaner.
Dust and dirt is part of its function and based on that I was almost sure that the lever that controls the motor was dirty; that is why it was not working; let us check it out.
I took all the screws off but the main one that was giving me a hard time was hidden under the power button. After I finally found it, I was able to take the top cover off and take a look inside the device.
I took the dirt bag and the filters out for cleaning; I headed directly to the faulty area.
As I took the two screws off I was able to reach the lever that controls the motor and I did something checking there.
As expect, it was dirty and needed some cleaning. I went ahead and cleaned this area and also checked the other side of it.
I gave it a shot of contact cleaning alcohol and re soldered the four soldering joints on the board.
I put the machine back together and tested it. The level was working just fine. I was able to control the speed of the motor. Customer was happy and the repair target was reached.
