    By idling, I mean “slow speed“ of course. Thank you.

    I have repaired several of this model the type 232. Some are easy like the video but some the carbon brushes will fly out of the black plastic arm. I used a thin .045 metal shim to hold them down so they wouldn't,t fly out from the springs then carfully slide it back into place. I also un hook the springs this allows the arm with brushes to exstend out past the circuit board making it far easier to install the board back in place.I lay the pedal on it,s side with the circuit board facing up it will be on the top side of the pedal.This also ensures the carbon brushes don,t fall out.

    Hello, I was very interested in your video, because I have an idling problem with the pedal (same as yours) on my Bernina electronic 830. So I removed and changed the capacitor of the pedal as you showed in the video, hoping same result. Unfortunately, the problem remained the same : on my Bernina, by pressing lightly on the pedal, the motor is starting directly at normal speed, but without idling, and accelerates to max speed, by pressing further. No idling. Maybe it's not coming from the pedal, I don't know. Could you please help ?

      Hi! You have a variable resistor you can adjust. Have you tried that? That adjust the "start speed".

      @@sewrepair Thank you for your quick reply. Of course, I had it turned left and right so as you did at the end, but there was no effect at all on mine.

      Hi ! I think of replacing this variable resistor. Maybe I could find one if I have the value of its resistance. Could you give me that information ? Thank you.

    Very nice video! I have got a bernina 530-2 record and it happens to have the same exact problem. The pedal is older (the beige one). Could you please send me a link of what kind of capacitor I need to buy? Thanks a lot 🙏♥️

    I have a bernina foot pedal type 230, can you replace the micro switch also?

    • @sewrepair

      It is possible to replace the microswitch, but it is a bit more work. I've done it a couple of times.

    Hello, I'm a textiles teacher with a Bernina 1008 foot pedal that has stopped working. Not sure if its age or problems with electricity surging in the classroom, as I have had 5 or 6 go this year. Its costing us 30 quid a time to fix them and new pedals are selling for over £100. Is there a replacement circuit board I can buy?

      Hi! I have repaired several such pedals for schools and there is one problem that is common. When the pedals fall to the floor, a large coil is knocked loose and one of the legs breaks. The coil has the designation CH on the printed circuit board. The result is that they stop working. It is possible to repair this error with a small wire and soldering iron. A new coil is usually not necessary. At least I've managed to fix all the ones I've had with this problem :)

    What voltage is that capacitor?

    • @sewrepair

      The one I use is 300VAC Be sure it is more than your main voltage.
