Sewing machines are bound to break down from time to time. The occurrence of issues, such as jamming and freezing, can be prevented by regular maintenance. In this post, we’ll talk about how to unfreeze a sewing machine.

Repairs and replacement of damaged parts should be done as soon as they happen to ensure that the sewing machine is in excellent condition every time it is needed.

Abuse, neglect, and exposure to environmental pressures are among the external factors that could lead to the freezing of your machine.

Frozen machines are a result of lint, dust, dirt, and debris crystallizing and encrusting of the same inside the sewing machines. Broken parts and problems in bobbin and hook assembly are also leading causes of frozen sewing machines.

Frozen sewing machines are unfortunately not easy to fix if the damage is extensive and has been left for a long time. But before the fixing phase, you need to identify the source of the freezing. Trying to turn the wheel will tell you if your machine is jammed or locked up stuck.

Some of the steps that you should undertake after noting that your sewing machine is frozen are:

  • Take out the bobbin and the carrier. If the hook assembly is a removable part, take it out too.
  • Try to turn the wheel to see if it has been freed up. If it moves, the problem is in the bobbin area. Clear the machine thoroughly, removing any debris accumulated. Other binding parts should be also be cleaned. Once the area is clean, replace the bobbin and enjoy sewing.
  • If the wheel is still stuck after the bobbin has been removed and the debris cleared out, it is time to check out other areas. Remove all the covers from the machine (top, bottom, and side covers).
  • Use an air compressor to blow out the machine to remove dust and any crystallized debris. Check out for threads stuck or wrapped around any parts and clear them out.
  • Brush away any lint, dust, and debris stuck on any part of the machine. Be careful not to brush away any removable parts that may be hard put back.
  • Lubricate the sewing machine and test to see if it is unfrozen.
  • In extreme cases, the above steps may not help you solve your problems. At this point, it is time to check the pulley assemblies, tensioner, and drive mechanisms.
  • Clean the areas associated with the pulley, tensioner, and drive systems and try to move the wheel again.
  • Remember to pay keen attention to areas where metal meets metal. Be sure to remove all the dirt, lint, and old grease from such parts before lubricating.
  • The process may sound easy, but once you get to it, you will notice that you may need solvents, heat, and energy to dislodge old lubricants.
  • This entire procedure may last anywhere from a few hours to a couple of days. This is because some parts may need to be soaked in solvents to remove the stuck-on dirt and oils.

Before you start this cleaning process, it is paramount that you inspect your sewing machine and establish the gear that you will require to handle the task.

In some instances, you may think that your sewing machine is frozen while, on the contrary, it is just jammed. The process involved in restoring your machine to full functionality is not as tedious and detailed as the one listed above.

For unjamming, stop all actions related to sewing and turn off your sewing machine if you are using the electronic powered models. Gently work to raise the needle up and away from the fabric and cut the thread linking the two. Try to remove the material by a tug. If it does not budge, raise it to access the threads underneath and cut them.

After the fabric is safely away from the machine, check the lower compartment and any issues that may be going on there. Check the bobbin to see if the thread is tangled and rectify. Re-assemble the bobbin system and install it, then thread your sewing machine and get back to work.


The techniques you employ to unfreeze your sewing machine depend on the extent of the damage done by the debris build-up. It is also vital that you handle the inner machine parts with care and not move anything that does not have to be moved. If you cannot control the extent of the damage on your sewing machine, contact the manufacturer or a qualified technician.
