Hello Lena,
The suppressor is what it says, it is there to suppress interference on things like radio and television, these items have suppressors built in and with the technology suppressors are not needed in machine motors that is why you can discard them if they burn out, with Bernina sometimes they wire the suppressor into the motor and forms part of the working part and it is not always possible to discard it, you will probably have to buy a new one and fit it, if the motor is labouring and struggling you may need a new motor which is very expensive.
