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.

SOURCE: Can not lower the needle to pick up bobbin thread on my Singer Stylist 7358 machine

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

I have a singer heavy duty 4423 I am sewing a curtain out of a sheet every time I try to reverse sew my machine jams up but straight sewing seems to be ok
If your Singer Heavy Duty 4423 is jamming when you try to sew in reverse, it may be due to a few issues:
  1. Thread tension: Make sure your thread tension is not too tight, which can cause the thread to bunch up and jam the machine. Try loosening the tension slightly.
  2. Needle: Make sure you are using the correct needle for the fabric you are sewing. A dull or damaged needle can cause the machine to jam.
  3. Bobbin: Check your bobbin to make sure it is threaded correctly and is not damaged.
  4. Machine maintenance: It's important to keep your machine clean and well-oiled. A buildup of lint or dirt can cause the machine to jam.
  5. Sewing speed: Slow down when sewing in reverse. Sometimes going too fast in reverse can cause the machine to jam.
If none of these solutions work, it may be a mechanical issue with the machine and it's best to take it to a professional for repair

Model 466. Why doesn't it pick up bobbin thread?
This means the rotary hook is not catching the top thread and looping it around the bobbin.

Be sure the needle is not bent and top thread is properly threaded. Be sure needle is properly oriented and seated in the needle bar.

Be sure you have bobbin properly wound, inserted, and threaded per machine instructions.

Download your owners manual from the Singer website at...

Try cleaning hook and race area if still having trouble.

If it was working fine and it recently broke a needle and/or jammed, the timing may have slipped.

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
make sure the bobbin is turned the right way in the bobbin case--this
can cause problems if the bobbin is turned the wrong way
make sure the bobbin is not warped or damaged
make sure there are no burrs in the bobbin area or on the needle

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.
