Singer heavy duty HD4411 thread jamming and solution 

Thank you for taking time to share this. I've been trying to fix my sewing machine and there was no video that could help

Holy hell this video was a really big help!!! It seems so obvious once you realize it ,but when you’re caught up troubleshooting and you’re looking at the bottom because that’s where the problem is, it’s hard to go back and think about the big picture. I wish I watched this video about 2 hours ago when I first started getting frustrated! I must’ve taken that bottom plate off and messed with the bobbin area components at least 25 times. 😮 Thanks for posting!

You’re a hero, I feel so stupid for not seeing the issue at the top

thank you! you saved me so much time and headache 👍

This saved my life! Thank you!!!

Thank you for this video!!! I’ve spent an hour pulling apart the guts of my machine with no luck…and this is exactly what was wrong.

Thanks! Such an easy fix but i spent like 20min re-evaluating if i had room temp IQ or not with the bobbin 😆 working great now

I saw the problem as soon as you said that the issue wasn't with the bobbin 😭 thanks a lot for the video

Thank you!! This seems to be the exact problem I was having. I’m a total newbie and this vid was the first result I found that helped

Omg you literally just help me with my problem.thank youuuuuuuu❤❤❤❤❤❤❤❤

thank you so much!!!!

This is a problem if you don't thread it right, but it's not the problem that causes the jamming issue with these models. The thread is getting caught on the lower right corner as it spins around the bobbin. That issue is happening on the lower half. When the sewing machine jams, when the threads get tight, they can lift the plastic piece that the bobbin rests in out of its proper position. You have to remove the foot, the needle, and bobbin, then remove the two screws on the bottom plate with the provided screwdriver, and then you need to lift the black bobbin seat out and place it back in correctly. When the thread jams are can cause the plastic piece to rotate counterclockwise and then the machine will constantly jam on the lower right corner of the bobbin housing as the thread goes around. If you reposition the black piece properly, the upper thread will not get stuck again.

This video helped a lot. Thanks

Thank you 😩😩😩

Very helpful! thanks!

What if you’re using a smaller thread the size of the bobbin ? I dnt use the big threads, I usually just thread a bunch of bobbins but my machine thread keeps getting Jammed or it breaks ever 2 mins
