Juki TL-2000Qi Foot Pedal
I have the same machine which I have had since May 2021. It was working fine a couple of days ago and when I went to sew this morning I have the same problem. I have sent Juki an email and will have to see how quick they respond. I have read on Facebook posts that this is a known issue.
Here's hoping our problem get resolved in a timely fashion. I looked online to see how much they are for replacement and they are about $170 US. I live in Canada so that will be much more than that. I do have another sewing machine that I can use in the interim but it is still disheartening.
Good luck to us both!
