Reason 1: Thread Cutter LED Blinks

  • You will need to remove the thread if it becomes trapped in the thread cutter mechanism since the LED light can also flicker.
  • Simply lowering the pressure foot will resolve this issue. 

Reason 2: Bobbin Problems

It shows when lint has built up in the bobbin holder or when the bobbin thread is not inserted properly into the bobbin holder. You will get more ideas from 60 wt vs 90 wt bobbin thread.


  • First, remove the bobbin, then release the thread tail. Reinstall the bobbin after which raise and lower the needle by turning the handwheel while lifting the bobbin thread. Resetting everything could solve the issue!

Reason 3: Needle Unthreading

This issue typically arises when the machine is improperly threaded or when the needle thread tension is excessively tight.


  • Before starting to stitch, make sure the presser foot is down.
  • Before you start stitching, gently pull the top and bobbin thread approximately six inches to the side.
  • As you make the first few stitches, hold onto the thread tails by pinching them between your fingers.

Reason 4: Broken Needles

This occurs when you use the incorrect needle or a blunt needle. Moreover, you may gently lay your palm on the cloth to help it go in the appropriate direction, but you shouldn’t push or tug the fabric since doing so might also result in the needle breaking! 


  • Make sure the needle clamp screw is completely tightened. 
  • Make sure the needle’s size and type correspond to the weight and kind of fabric you intend to use.
  • Make sure to correctly position the needle.
  • Make sure the fabric is moved beneath the needle by the feed dogs. 

Reason 5: Squeaking Noise

If you are sewing and you hear a squeaky sound, stop sewing right away. A squeaking or peeping sound during sewing. Another possibility is for using it for a long time and not used any oil to remove dirt. To use suitable oils, you will get ideas from 3 In 1 Oil Suitable For A Sewing Machine.


You have to bear in mind that current machines are sealed and pre-lubricated, so unless your handbook specifically says otherwise, you do not need to add oil. Helmar’s SuperLube Oil and Premium Accessories Pharmaceutical Grade Sewing Machine Oil are best to use.

Reason 6: Grinding Noise

The machine may occasionally produce this noise when it strains to stitch but is unable to move the cloth due to a thread jam. This problem frequently occurs when dust and lint collect inside your machine’s moving components.


  • Use a clean cosmetics brush or lint brush to clean the bobbin region. Get started by removing the bobbin and bobbin casing. 
  • If your bobbin is top-loading, you must first take the presser foot and needle out in order to completely clean the bobbin region. 
  • Finally, brush any lint away from the feed dogs with caution.

Reason 7: Skipped Stitches

You have an issue if you inspect a seam and notice spaces between the threads on the fabric’s surface. 


  • First, you have to put a new needle in. 
  • Use the proper needle for each stitching job
  • A different sort of needle is needed for silky fabric than for canvas or cotton, for instance.
  • Then, increase the upper tension settings by one and check the results. If it doesn’t, try a lower number.

Reason 9: Tight Stitching

Numerous factors, like tension settings and material type, can cause tight or puckered stitching.


  • Check the tension settings to see whether the highest tension needs to be lowered.
  • Then make sure to match the cloth and the needle.
  • To avoid puckered-seams, you might need to interface between your fabrics. This is especially useful for fabrics that are slinky or light.

Reason 10: Loose Stitching

The majority of the time, incorrect machine threading is the cause of loose stitching. The thread must precisely loop around every small guide and tension disc for the machine to be able to apply tension to it. It creates slack, shaky stitches when there isn’t tension.


  • Check the size and kind of the needle to verify if it’s made for the cloth and thread you’re using.
  • Have to check the tension settings on your top belt. 

Reason 11: Tension Issues

If your seams get tight and puckered or if you detect loose or saggy stitching, you may be experiencing tension problems. 


  • To determine whether the increased tension solves the issue, increase the tension setting by one and attempt stitching once again.
  • However, if the threads on top of the fabric appear loose, consider lowering the tension by one number before performing another test stitch.
  • Lower the tension if the seams get tight or puckered.

Reason 12: Thread Tangles

Thread tangles are typically the result of an issue with the top thread. Sometimes using the incorrect sort of thread for the type of fabric results in thread tangles. 


  • Remove the old thread by snipping it close to the spool and then gently drawing it down and out through the needle.
  • Place the thread on the spool pin and unwind six to ten inches of loose thread.
  • Next, follow the thread path. Keep moving the thread left to the next thread guide.

Reason 13: Fabric Stuck

Sometimes when sewing, the cloth won’t feed through the needle because you failed to press the presser foot down first.


  • Make sure everything is adjusted for regular stitching.
  • Similarly, you might need to reset for a conventional straight stitch if you had the double-needle stitch setting activated.
  • Solve if you face any jamming issues.
  • For straight stitching you can use Tiger Tape and more details you will get from Prevent Thread Tangles in Hand Sewing

Reason 14: Jamming

The most common reason for sewing machine jams is an issue with the top thread. The thread may have come loose from a tension disc or thread guide.


  • First, use a pair of small, precise embroidery scissors to cut through the thread holding the cloth in place until you can pull it out.
  • Remove any loose thread fragments that may be adhering to the bobbin case by opening it up.
  • Make sure there are no tangled threads caught behind the needle plate before removing it with a little screwdriver. 
  • Rethread the top thread and reinstall the bobbin. To properly line the tension discs, lift the presser foot before threading. check a few test stitches on a piece of cloth to check sure everything is functioning properly.
  • If you immediately have another jam, the top tension definitely has to be adjusted accordingly. 

Reason 15: Not Stitching

If your Janome sewing machine refuses to stitch, several different issues could be at play. You must fix all the jams otherwise you would face several problems to stitch your clothes or other parts not fitting well. 


  • First, examine the foot pedal and power cord connectors. 
  • Make sure the machine has been adjusted for sewing rather than bobbin winding. 
  • A thread tangle can appear so you have to remove jammed clothes from your machine.
