Causes of SINGER M1605 Sewing machine Upper Thread Breaking

Don’t let thread breakage on your SINGER M1605 sewing machine wreck all of your hard work. There are a few potential culprits that can be quickly corrected in order to bring everything back into alignment. Improper needle placement or threading, overly tight tension settings, and even having a dulled/crooked needle point could easily explain why threads might split away from the cloth while you sew.

Furthermore, the thread size might not be compatible with the corresponding needle size; burrs on presser feet often snag fabric and cause issues; needles that are too long for this machine specification can also be a problem; worn out take-up springs or overly used tension discs containing grooves add to these difficulties.

To guarantee a seamless sewing session with your SINGER M1605machine, it’s vital to tackle the unequal speeds of stitching or else you may encounter snapped threads. When all these variables are thoughtfully considered upfront, remarkable results will be achieved.

Here are 9 the most common causes of upper thread breaking on a SINGER M1605 sewing machine and how you can fix them:

Your SINGER M1605 Sewing machine Is Not Threaded Correctly

To ensure the best possible performance and highest efficiency from your SINGER M1605 sewing machine, it is critical to correctly thread the upper yarn. This simple step will prevent any potential breaks in the upper thread and protect against future difficulties.

How to Correctly Thread a SINGER M1605 Sewing Machine?

Although this is a straightforward task, it’s essential to get it right – otherwise, you may end up with some serious sewing issues.

Threading the Upper Thread:

  • Rotate the handwheel counterclockwise until the mark on it is facing upwards. This will elevate your needle to its peak position. Once finished, lift up the presser foot in order to undo any tension that may be set by the discs.(1)
  • Securely affix the thread and spool pin felt (a) onto the spool pin for optimal results.(2)

Note: For safety reasons, make sure to turn off the power before threading – it is strongly recommended!

  • Carefully draw the thread from the spool and guide it through the upper thread guide. (3)
  • Carefully maneuver the thread around the thread guide as shown in the illustration. (4)
  • To tension your thread, draw the thread down right channel and up to the left-hand channel. (5) For best results, hold onto the thread between its spool and guide as you do this.
  • At the top of this movement pass thread from right to left through the slotted eye of the take-up lever and then downwards again. (6)
  • Guide the thread behind the slender wire needle clamp guide (7) and then underneath it to the needle which should be threaded from front to back.
  • Gently tug about 6-8 inches of thread away from the needle eye, then neatly cut it to length with the built-in thread cutter. (8)

Your SINGER M1605 Sewing machine Thread Tension Is Too Tight. Adjusting Thread Tension on SINGER M1605 Machine for Even Stitches

To guarantee even thread tension with the SINGER M1605 sewing machine, fine-tune according to fabric and thread weight. To prevent snapped threads while pulling too hard on your threads – simply rotate the dial counterclockwise for lighter pressure. If experiencing difficulty in optimizing bobbin tension or any other issue arises, don’t hesitate to seek help from a qualified technician promptly.

Your SINGER M1605 Sewing machine Thread Is Poor Quality

As a SINGER M1605 sewing machine user, it is critical to use the highest quality thread for your projects. Avoid taking chances with weak threads that can easily snap and thick ones which might possibly clog up in the needle/tension discs.

To guarantee ideal results without any glitches throughout usage, be sure to purchase superior-grade threads specifically crafted for SINGER M1605 machines! You won’t regret investing in the best possible materials – they ensure seamless stitching session every time.

Your SINGER M1605 Sewing machine Needle Is Damaged, Bent, or Dull

With extended sewing of heavy fabrics, the SINGER M1605 needle may become damaged or bent. Additionally, there is an opportunity that it might be defective from manufacturing errors.

If you suspect deformation of needle, it’s definitely worth replacing the existing one for optimal performance! For best results we recommend switching out your needle after each project; however, if you find yourself dealing with more thread breakage than usual while sewing then its time to get a new needle.

You Are Not Using the Correct Needle in SINGER M1605 Sewing machine

To ensure your SINGER M1605 runs smoothly and avoid any jams or thread breakage, it’s essential to swap out the needle prior to each project. This is especially important if you’re working on thicker fabrics like leather, corduroy or denim – they require specialty needles that can handle increased thickness. By selecting the appropriate needle for each job, you’ll greatly reduce the chances of snapped threads and hassle-free sewing!

Your SINGER M1605 Sewing machine Needle Is Not Inserted Correctly

For the best stitching performance, correctly insert your SINGER M1605 sewing machine needle – with one flat side placed towards the back of your machine. When inserting the needle, be aware of the flat side that should face towards the back of your SINGER M1605 sewing machine–this is located atop its shank. With this knowledge in mind, you’ll reap reliable and consistent results each time.

To avoid a possible catastrophic event, double check that your needle is inserted all the way up and fastened securely. If you notice the screw has become loose or if it gets bumped, take extra precaution to make sure the needle isn’t hitting any part of your SINGER M1605 sewing machine such as the bobbin case or throat plate. It’s also important to ensure you’re not inserting it backward – this can lead to breaking of needles too.

Your SINGER M1605 Sewing machine Take-Up Lever Spring Is Broken

If you’re having difficulty starting to sew or your thread breaks right away, the SINGER M1605 sewing machine may have a broken or bent take-up lever spring that needs to be replaced. To ensure accuracy and safety, it’s best for this issue to be addressed by an experienced professional repair technician.

Your SINGER M1605 Sewing machine Bobbin Case Is Full of Lint

To avoid annoying thread breakage, it is essential to keep your SINGER M1605 sewing machine free of any lint build-up in the bobbin case. This will ensure seam stitching remains smooth and snarls are avoided, without disrupting the hook timing. Taking proper care of this machine will guarantee you beautiful results every single time.

You Are Sewing Too Fast

If you’re in a rush when sewing with your SINGER M1605 machine or any other project, the tension may become uneven and cause the thread to snap. To avoid this, it’s essential that you take your time – particularly if there are multiple layers of fabric involved. This will give the machine enough room for making its secure stitch without weakening threads. So remember: slow and steady wins the race.


Thread-breaking issues with your SINGER M1605 sewing machine can be due to an array of underlying problems, including incorrect needle insertion, unsuitable needle size for the fabric being used, inappropriate thread tension, or a broken/bent lever spring. To ensure successful results and prevent further interruptions in future projects you embark on with this equipment-proper maintenance and troubleshooting are essential steps that should not be overlooked.
