Question about Singer Quantum 9940 Computerized Sewing Machine

1 Answer

Electronic alert keeps coming on but the machine is running fine?

Hi, I'm having a problem with my singer 9940. The machine is running perfect except the electronic alert keeps popping up while I sew. It's the one that shows the presser foot then the bobbin. I have tried cleaning it, blowing it out with canned air. It is correctly threaded I don't know what else to do?

    Hi thanks I just tried it. Still isn't working. I have changed thread several times, presser feet. It will make about 10 stiches the pause with the alarm and then start over for 10 stitches.

Try replacing the needle. it may be just ever so slightly bent. You can not tell. causing more downforce on the machine.

My Singer Quantum 9940 keeps stopping and displaying threading problem. I've re-threaded it 100's of times but it still stops after one inch of sewing!

There may be something in the tensioners. Try to clean between the tension discs with a business card. Maybe this will help

I try to make a button hole with the 9940 Singer machine and I continue to come up with the machine doing nothing. I follow the directions in the manual, the presser foot I've changed to the correct one...

To the left of the foot there is a silver button hole lever pull this down fully.

Make a note in your handbook for next time as recently this happen to me and it took me hours to work it out.

Hope this is your answer.
