Sewing Machine diagnosis 101
#21
The thing that really gets me about some of the even expensive newer machines is all those pulse motors returning to zero" when you turn them on. I can handle the noise of them sewing, but the clicks and clunks when they start up.
Wow. I ducked the first time! LOL!
A lot of the troubleshooting stuff is similar with the computerized machines. Mechanically they're really similar, and timing is timing. It's once it starts to "flake out" that it gets harder - the computer stuff is often a voltage problem so it's not consistently a bad or a good, sometimes it's whatever it wants. At that point though, modules, boards or whatever are replaced not repaired. Of course the other thing is if it' computerized and worth the cost of replacing a board, it's probably still on warranty and in a shop with a technician who has the service manuals.
The other fun diagnostic thing is trying to figure out what's really wrong when someone tells you what's wrong with the machine.
