/diy/ - Do It Yourself

Hello, I am trying to fix my vacuum cleaner. The problem with it is that the roller is not activating like it is supposed to. There is a small switch that is depressed when the vacuum is in upright position. When you pull back the vacuum to start using it, the switch is released and the roller motor is supposed to start. Mine takes many tries to get the motor to come on, and then it will usually turn off immediately after. I have taken the vacuum apart and now I know that it is not a mechanical issue but an electronic one.

Do you guys think this issue could be fixed by replacing the switch? Or is it the motor that is malfunctioning? Is it worth it to try and replace parts on this or is it a lost cause? Thank you
