Question about Kenmore Drop-In Bobbin 505S-21BH Mechanical Sewing Machine

1 Answer

Kenmore 385 Series with drop in bobbin

Inadvertently, ran over the head of a pin and the bobbin jammed. Cleaned everything out, but the top thread keeps getting stuck in the bobbin area. I've tried resetting the black piece underneath, but it doesn't seem to stay put and it jams the top thread again and again. Can you help? With much thanks!

It might be that a piece os the pin is still stuck in the bobbin race. try taking the screws out of the throat plate and lifting it up. use a little brush to make sure allthe lint and any pin pieces are out from around the feed dogs. put the black piece back in place before you replace the throat plate. If the black piece doesn't stay in place i doubt that it was in correctly. hope this works.

I have a Kenmore 385 19153 the thread is breaking any keeps jamming in the bobbin

Could be threaded incorrectly. Remove the thread from the machine. Put in a brand new needle.. ALWAYS RAISE the presser foot and rethread the top thread from the beginning. (AVOID old or bargain bin thread--might even try a different type of thread.) Check that the thread path is correct. Then put bobbin in the bobbin case and thread it through the tension. Check that the bobbin is turning the correct direction in the bobbin case. Install the bobbin case in the machine. Start out with the top tension set about the midway point and then tweak it from there to get the appropriate tension.

Pull the bobbin thread to the top of the fabric and gently hold both thread tails in your left hand while you slowly take the first few stitches.

If you continue to have issues, then you may need to have your machine serviced. It could be out of time or perhaps there is a snag or burr that is catching the thread.

I have a husquavarna 875. the thread is jamming in behind the bobbin. i have re threaded, changed the bobbin and cleaned the bobbin area of any lint or thread. any ideas?

Is the top thread coming down in the rotary hook and then jamming? if so, review the top tension and top threading and see if you've missed a thread eye somewhere, particularly the thread take up lever or if the thread is actually under enough tension on top.

You can test the top tension by lower the pressure foot and then pulling the thread downwards after its feed through the tension device, it should feel firm but give to a firm tug.

If this isn't happening, try rethreading it, cleaning it out and adjusting top tension to get it firmer. Generally 4 is a good setting so just make sure it hasn't been adjusted inadvertently.

There is also good trouble shooting help at which may help you to identify what's causing this problem. Check also that the bobbin is the correct one for your machine, and in and rotating in the right direction. But if it is the top thread jamming into the bobbin race its probably top tension.

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.

My Kenmore sewing maching 385-19233 has problems with the tension. the lower thread is coming out with tiny loops - almost like a double thread. I am not able to correct it by adjusting the tension dial,...

Usually, it is the top thread causing the problem. Rethread entire machine. Then, pull both threads (upper and lower) with the presser foot up and leave a 6" tail. Make sure that you do not miss any guides, check your manual to make sure that you haven't missed a guide in your threading, and the direction of your thread on both bobbin and upper going the right way Youtube has excellent videos on threading for free..

Need help with my kenmore 385 sewing machine, it makes a loud knocking sound and then jams. I have cleaned the the feeding dogs and the hook and bobbin, everything is threaded and tension is correct.

Try unscrewing the screws on the throat plate, you will find more lint and thread there. I never knew to do that until someone told me about it because I thought that all you had to do was clean out the shuttle area. Hope this helps.

I do not know how to thread my kenmore 385 sewing machine. I also need to know how to thread the bobbin.

They have threading diagrams for Kenmore 385 models here.
Scroll down until you get to the Kenmore section.
I think they include bobbin winding etc.
Hope this helps!

Kenmore 385 model Automatic Button Hole Apparatus Jams Thread?

Practice and practice some more! Use the same fabric and interfacing as your project and a NEW needle (the correct needle) This is for the Sears Kenmore 385 automatic button hole maker. Make sure you pull the bobbin thread through the Guide Block - it is that simple. Make sure you pull your thread to the back of the machine though the presser foot slot - the correct presser foot. Account for both thread tails before starting to sew. Keep thread tails to the back of the machine 4-5", insert fabric under presser foot keeping thread tails clear. Mark button hole and sew.

Bunched bobbin thread

Try changing the needle. If you're using the wrong needle for the type of fabric, this could happen.

Kenmore 385. 11607 needle jams into shuttle or shuttle race

I had the same problem with cleaning and jamming and this might sound silly, but when you're in the middle of trying to fix it remember to look up see that it is threaded up top. I did everything the pp's suggested and when they didn't work I realized the top thread wasn't still threaded around the tension thing anymore. After rethreading it, it worked fine. But I DID reduce the amount of thread on the bobbin at the same time as Drazil suggested.
