  Thread breakage in your Singer Sewing Machine can occur due to several reasons. It could be that the machine isn't threaded correctly, or the thread is not unwinding smoothly from the spool. Other potential causes include a bent, dull, or broken needle, incorrect needle insertion, poor quality thread, thread tension set too tight, or the thread getting caught in one of the thread guides. Check the threading path, replace the needle if necessary, use good quality thread, and ensure the thread spool isn't getting caught. Also, make sure the thread tension isn't too tight.

What to do if my Singer S14-78 Sewing Machine is jamming fabric?
- S
  Stephanie HunterAug 27, 2025
  Fabric jams in your Singer Sewing Machine can occur if the upper and lower fabric cutters are not in the proper position. Check the alignment of the cutters. Another cause could be the thread not unreeling smoothly off the thread spool. Check the thread spool. Also, too much fabric thickness can cause jams. Compress thick layers with a conventional sewing machine before sewing on your overlock machine.

Why is the needle breaking on my Singer Sewing Machine?
- L
  Lisa SuttonAug 31, 2025
  A broken needle on your Singer Sewing Machine can occur if the needle isn't properly seated in the needle clamp. Ensure the needle is fully inserted into the clamp and the screw is tightened securely. Another cause could be manually pulling the fabric, which deflects the needle. Avoid pulling the fabric; let the feed teeth draw it through. Finally, the needle size might not be correct for the fabric. Use a needle size compatible with the fabric you're sewing.
