Singer 9432 my bobbin thread is big loops and bunched up i change tension but does not help

hi Sue.
Why does my bobbin thread keep bunching up? Check Your Tension Settings. Looping underneath the fabric usually occurs when there is not enough tension in the needle thread to pull the bobbin thread. Sometimes thread bunching can be caused by something as simple as the tension dial being inadvertently turned.

what you describe is thread bunching and is typical of the needle thread tension being too loose
adjust that right up, run a test sew and go from there

Is it really the bobbin thread that is globbing? Check closely. Usually it is the upper thread accumulating under the fabric.

If it is in fact the bobbin thread, then the bobbin case is not threaded correctly, the bobbin case tension needs adjustment, or it is broken and needs replacement. There are web sites and YouTube videos that show how to adjust the bobbin case tension.

QUICK FIXES: Remove all the thread from the machine. Clean the area around the feed dogs and bobbin area. Oil as instructed in the owner's manual using ONLY fresh, good quality sewing machine oil (only 1-2 drops each spot). Install a brand new needle insuring it is installed correctly. Avoid using fuzzy, old, or bargain bin thread. Rethread: Be sure you raise the presser foot BEFORE threading the upper thread so it will seat properly in the tension disk--and check to make sure you are threading the machine correctly. Check that the upper tension is set properly (the factory standard is usually the halfway point between the high & low number on the selection). Test on a scrap of the fabric you wish to sew. Adjust the upper tension--either tighten to pull the upper thread toward the top of the fabric, or loosen to pull more upper thread down.

Found several answers at this site, mostly addressing the tensioner.

Top tension too loose causes looping under, unless the tension balance is affected when you "cleaned" the bobbin case

Make sure you have the correct bobbin, 66 class. Check the bobbin case. These machines use the apollo bobbin case that tend to get broken and then the thread hangs up.

Take the thread completly off the machine and rethread it making sure it goes thru the tension wheel properly.
FYI Loops on the bottom-- Problem is in the threadding.. Loops on the top, problem is with the bobbin.

For normal everyday fabric, tension should be 3-5.
If it is looping on the bottom, the problem is the threading of the machine. If it loops on the top then the problem is with the bobbin.

Any time you have looping on the bottom, it is almost always related to the upper tension and not anything in the bobbin area.
A good way to troubleshoot this is to turn the machine off, blow out the upper tension disk assemblies with canned air, (the machine needs to be off because most canned air uses butane as a propellant. Butane + electricity = bad;) replace your needle, and rethread your machine. Once you've threaded it to the point where you're about to put the thread through the needle, "floss" the thread forward and backward to ensure that the thread seats correctly into the tension assemblies.
Set your tension to around 4.5 for most applications, and drop your presser foot. Give the thread a gentle tug to see if the tensions have engaged the thread, then thread the needle.

If doing this does not address the problem, you probably need to have your tensions professionally calibrated. This is also true if the needle is in fact hitting something in the bobbin area. This is usually caused by the machine's timing being out of alignment, which is not something that can be fixed at home.

Good luck,
