I have a 2010 Millenium that has developed a problem.
The first thing I noticed today was that when I used the needle up/needle down button it would frequently hesitate as the needle was moving down through the quilt, and sometimes would go up and down twice even though I only hit the button once.
I moved the machine off to the side, unthreaded it and removed the bobbin, and then let it run in manual mode. That's when I realized that every couple of seconds the machine hesitates and then speeds up before resuming a normal, steady speed.
I have turned it off, unplugged it, made sure all of the connections are firmly seated, and turned it back on - still the same problem.
Does anyone have any suggestions about what could be causing this and how to fix it? I'm starting to feel queasy thinking about the twenty or so customer quilts that are waiting for me!
Thanks in advance!
