Just posted on another thread called 'trouble with my Juki 2010Q...errrrggg - trouble with mine, too, after only three days! Today, in the middle of perfectly straightforward sewing, and with no thread jams anywhere, or any machine complaining, it stopped dead. Nothing working except the light. So it's not a fuse. Honestly, why is nothing simple!! Even with a totally simple, mechanical machine. I've contacted the dealer who asked me to What'sApp him a video but there's nothing to see, except that the light is on. Then, lo and behold, after a half hour's 'rest' it's working again. I've asked if I should hang in there and see if this is a problem that repeats, but I'm really not happy that a brand new machine should have any reason at all to stop suddenly; there must surely be something wrong somewhere.
