Roomba 4XX Brushes

After running diagnostics, I have determined that my main brushes do not turn on at all. How do I determine if it is the motor, the motherboard, or something else?

Hi,

You can easily determine if the problem is the motor or the motherboard, by plugging the motor to an external source, such as a power supply. If the motor is working then it’s probably a motherboard issue.

If you cannot access to a power supply, we suggest you to purchase one of them, and replace it. You can always return your part if it doesn’t work.
