Needle gets bound up when sewing - Singer 5062 Mechanical Sewing Machine

Bobbin threaded correctly? Needle not bent and correct size for material? Old thread, cheap thread?
Underneath packed with lint? Needle threaded correctly. Just some things to look for :)

Check whether there is thread twisted/knotted in the bobbin area of the machine. This will need to be cleaned out in order to release the bound needle.

Ensure needle/needle bar is fully up at its highest point, replace the bobbin case with its open end seated at the back, the rotary hook tip should be just underneath it, just check further that it resides nicely along the groove of the rotary hook, re install the needle plate cover and tighten the 2 holding screws so that the bobbin case can be nicely in place, manually and slowly hand wheel the needle down several time to ensure the bobbin case is not unseated/needle is not knocking the bobbin case. Hope this can help/otherwise there are adjustments that need your local technician to do it.

Are you talking about the flywheel? The knob that turns when you are stitching? If that is the problem, then there is something bound up in y our machine. Unthread the whole thing. Will it turn? If not, take out the bobbin and try to turn it Check your needle to see if it is bent. If none of these work you will probably have to take it in for service. I recommend finding an independent repair shop rather than a sewing machine store. They are considerably less expensive, and can get the work done in a fraction of the time. Best wishes to getting back to sewing!

Something is bound up. Stop trying to sew. Turn off the machine.
Take off the foot, take out the needle, take off the bobbin cover, take of the needle/throat plate and check for the reason for your problem. Look for lint, threads caught up underneath and in between the parts.

Clear all that out and put it back together and attempt test seam.

It's bound up with broken threads.. clean the bobbin area.

try changing the needle--make sure the needle is correct for the fabric
clean under the needle plate & in the bobbin area for lint or loose threads
if it keeps jamming up & making noises I suggest to have the machine
serviced

Remove the throat/needle plate and see if thread has wrapped around the mechanics...clean the area to remove lint accumulation.

If the machine is still bound-up, it will need to go in for repairs.

Chance the needle making sure it is aligned when you tighten it. Check the bobbin to see if it is bound up by thread and the last thing is try another bobbin.

I have the same machine. Try replacing the needle, it could be slightly bent and not be in position to pick up the loop from underneath. A good de-fluff may help too.
