Guide :Sewing Machines : Quantum 9940 Computerized Sewing Machine
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?
