Thanks for this; it is all really good information. years ago I worked in a shirt factory and there were days when it rained that the atmosphere would cause the machine to act up. the next day it was good. I have very little problems with my Kenmore/Janome machine but normally when I do I do what I tell the users here at the hospital (I work in the IT dept) reboot and sometimes that means shut it off for a few minutes; have a cup of coffee and go back and it is usually good by that time.
