Why do threads break on my Brother 3034D Sewing Machine?
- VvjacksonJul 31, 2025
Several factors can cause threads to break. Make sure the machine is threaded correctly, and check the spool pin and thread holders for any tangles. Adjust the thread tension if it's too tight, and ensure needles are installed correctly. Using the correct needle, such as Schmetz 130/705H, is also important.
