Sewing Machine Upper Thread Tension Not Working?

My Viking, model 400, upper thread tension is not working. I didn't notice until I tried using a free motion quilting foot and lowered the feed dogs. I started on a test quilt sandwich and the top looked fine, but there was a loopy mess on the bottom. I tried to increase the upper tension, no change.

Lowered the upper tension, no change. Then I noticed that whether the tension was on zero or 9, when I manually pulled the thread through, the thread pulled through so easily either way. No squeezing there is happening at all even though it gets harder to turn the dial toward 9.

The computerised Scandinavia 400, or a vintage, mechanical or electronic model sharing the 400 designation?

If it is a vintage model, it sounds as though your upper tension discs are in need of a tune-up. Any repair tech can fix this for under $100USD including a general once-over for any other problems and a nice interior clean-up as well.

However, if you are talking about the computerised machine:

Check the manual for troubleshooting info-follow the manual instructions before anything else to protect your software and warranty. Usually the manual will recommend a 'safe reboot' and will list instructions on doing so.

If the problem persists after a safe reboot you will need to take the machine to a professional, there is nothing-repeat nothing-you can do at home to resolve your issue.

Computerised machines that go wonky should be looked at by a brand certified tech. Partly to protect any installed software and warranty, but mostly because they are the only people who really are able to suss a problem-they have the tools and training.

Take your machine to a Husky-Viking dealer to be sure the tech is a brand certified tech as software and motherboards vary from brand to brand-what works on a Necchi won't work on a Viking, for example.

Because the computerised machines are very pricey and bring in most of their business, dealers want to protect their reputations for continued and repeat business. So they only use brand certified techs to avoid the dreaded 'Well, I took my Viking to (insert business name here) and they really wrecked my machine-I wouldn't go there again no matter what!'
