How to repair a sticky/jammed singer heavy duty 4423

I had some problems with the thread jamming the machine, so i took all the thread out but the machine is still jammed. took off the plate over the bobbin and the case off over the light but I can't see what is causing the machine to stick. I can use the hand wheel to make the machine run about 1/2 a revolution before it becomes to stuck to move farther. I've only used the machine a few times so it shouldn't need to be oiled.

    i replaced the needle and that took care of some of the stickiness the machine is having. i can hear something rubbing together that wasn't before but cannot see what it is.

    the machine is up and running but with a really annoying high pitched squealing noise. pretty sure i just need to clean the lint out now.

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!

Since you still hear a high pitch squealing noise then it might be a good idea to have the machine serviced to see if there is anything wrong inside the machine

Maybe, try a new needle, and make sure that the flat side faces the rear. And try it 2 or 3 turns on the wheel. Oil your machine if you haven't used it in a while. I am hoping that it is not your timing and have my fingers crossed.

Generally, this is because the needle is either inserted incorrectly or because it's bent. Even if it doesn't look bent, it can be ever so slightly that you can't even see it with the naked eye. See if changing the needle corrects the problem, and be sure to insert the needle with the flat side of the shaft facing away from you.

Good luck, Linda!

Hello

Have you replaced the needle? Sometimes something that simple will solve the problem.

If you have changed the needle and rethreaded the machine, then take apart your bobbin and make certain there are no small pieces of thread or lint in it.

Check your tension. Do you have an automatic thread cutter? I had the same problem and it was because my automatic thread cutter was cutting the thread too short. Some how the cutter had gotten bent...I could not tell it, but it was.

To solve the problem i put the blade of a flat head screw driver under the cutter and GENTLY bent it back down. Fixed the problem. Works perfectly.

some machines can get "out of time"...the needle and the bobbin thread don't arrive at the right place at the same time.In this case you need to take your machine to a repair shop for re-timing

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.

My Singer Heavy Duty 4423 has a problem getting the bobbin thread to come up


First make sure the needle is the correct size and fully inserted into the machine. Test

Then if that doesn't solve the problem check the timing.

Good luck

Hello. I own a Singer 4423 Heavy Duty sewing machine. It has been working fine overall, but today it is giving me problems with jamming. At first it jammed underneath the plate and created a huge ball of...


Make sure thread is not laying across the bobbin when you look down into the plastic slider that covers the top loading bobbin case. The bobbin on mine I observed was loose in the case so that as the machine ran, eventually the bobbin thread would jump out of the stitch finger (the silver piece to the far left of the bobbin case, past the tension slots). I solved this problem and so can you! Take the extra felt spool pin felt in your accessories kit that came with the machine, remove bobbin from case and drop this small felt circle into the bobbin case. Replace bobbin. On the 4423, the bobbin thread goes counter-clockwise and drops into the tension discs, and goes all the back until it falls into the space left of the silver stitch finger. Make sure take up level raised all the way up! Then pull the needle thread toward you until bobbin thread comes all the way up. If you start sewing and you actually can SEE the bobbin thread laying across the bobbin, STOP and tethered because that would mean your thread did not slide all the back behind the silver stitch finger--however, I assure you, if you go one step at a time, you did it correctly! You will be smiling in no time! Why? The felt helps to make the bobbin rest in the correct position to keep it from jumping out of the groove. I hope this helps you.
