Sewing Machine Jammed

I have just acquired a sewing machine the make is a JMB, it's all threaded up etc., but the needle won't go all the way down and it just freezes and makes a buzzing sound. The tension is on 3, but I have tried it on other numbers and still nothing. Has anyone got any tips I should try? x

Hi Jennifer! Is your model an overlocker or a standard sewing machine? I'm not familiar with the JMB machines at all as I sew vintage and antique Singers exclusively. So I'm going to ask if you have the owner guide (user manual)-that should have a troubleshooting section that might help.

I will say if this were happening on one of my Singers I would clean the bobbin case and area, the tension disc areas, and then I'd try a rethread-I have had the same problem you describe happen on the Singers when I've threaded the machine wrong-lol, usually either passing the thread BEHIND the tension discs instead of between them, or when I've been in too big a hurry and forgot to raise the presser foot when threading the machine.


If you still have trouble, it could be something inside the machine and the best person to have a look is a qualified sewing machine repair technician. If you live in the US or the UK, a good repairman is as close as your local sewing centre-the staff there can recommend someone. The cost varies from country to country, US around $50, UK around £35-£60. You'll get your machine back in working order and it will have been serviced (clean, oil if needed, other potential problems found, repaired if you agree to the work being done). Well worth the money if you love or need your sewing machine!

If you don't have the owner guide, try a Google search using the manufacturer name and the machine model number in the search term. I tried to find a free download for you but since I don't know anything about JMB machines my search wasn't productive.
