Wow, what a challenge. There are a lot of reviews/complaints about how temperamental this model is- sewers either love it or hate it and have the same problems you describe. Since I am an experienced sewer and have lots of vintage black Singer models, ( I got rid of the newer models), I wouldn't mess with it any further...If you can, take it to a Singer authorized repair person....they can sort it out for you. Sounds like you've done everything you could so far. Good Luck.

Where the bobin is at re check the exterior of the part that spins you may have a thread stuck and keeping it in place use a flash light then replace bobbin as you depress the power controller asist the wheel this should free up the bobbin area and should run

Why is the bobbin case on a Singer 4423.CL - Heavy Duty 4423 not working right?


If you've cleaned and oiled it, change the needle to see if it is catching in the wrong place and re-thread, of course. If none of that works, it's probably the timing ... find a good repair guy.

Machine jams after 4 or 5 stitches. Bobbin thread locks up.


try these suggestions
change the needle
make sure the thread doesn't come off the thread take up lever--this
can jam the machine

can cause problems if the bobbin is turned the wrong way

How to repair a sticky/jammed singer heavy duty 4423


Put a felt spool pin holder (an extra one comes with machine and it's either red or white felt with a circle cut out of it in the center)...remove bobbin, set felt circle in bobbin case to keep bobbin from wiggling. The back and forth motion is knocking the thread out causing it to lay flat against top of the bobbin when you start machine, but felt puts bobbin in correct position! Make sure thread falls into tension slots and carefully pull thread back to left of silver piece (stitch finger). Pull up your bobbin thread. Put in new needle since "bird nesting" or jam may have bent the one previously used. Now it should purr like a kitten...smooth sailing! This is how I fixed my Singer Heavy Duty 4423 when I realized the problem is that the bobbin case is a bit wide and felt takes up slack, raising bobbin also to keep bobbin thread moving smoothly through so it doesn't jump out of tension and rest on top of bobbin!!! Works now!

Singer simple the machine keeps jaming


I would say that the threading is wrong somewhere, watch your dvd and read the owners manual, also go to Singer.com FAQ for your machine, If the jamming is underneath, it is the top threading problem, on top, it is the bobbin thread either has lint or stray thread or thread not coming out the right direction for your bobbin, I am sure that it is just a simple solution, I also use metal SA 156 bobbins and have no problems,

Keeps getting jammed


Hello,
Give these solutions a try.

* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your
bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.

* Change your bobbin as there could be a nick along the edge of your bobbin spool that’s catching your thread as you sew.

* When you start to sew a seam, Hold the upper and bobbin thread tails back and out of the way as you sew your first couple of stitches. This will keep them from getting jammed in your machine.

I hope this helps.

Thread jamming on the bottom of fabric


The tension must have gotten loose during use, try adjust the tension on the thread, and the bobbin casing.

How do i put the bobbin case back in correctly?


The zigzag setting should not have caused it to jam up unless the tensions were off and the thread was bunching up on the bottomside of the needle plate. If you ever jam or break a needle be sure to replace it with a fresh new needle. A slightly bent needle will cause all kinds of problems.
When putting the bobbin back in make sure you keep a good amount of thread hanging out and manually turn the hand wheel around until the needle make a full rotation. The hook should catch the needle thread and allow you to pull the bobbin thread out through the needle plate.
If you jammed it really good it is possible that the needle and hook timing is out of sync in which case you may need to have it re-timed.
