Serger needle is hitting the lower looper
This problem is caused by the serger needles and/or the lower looper being out of alignment, which then causes them to hit each other. The easiest fix for this problem is to check that your needles are properly positioned in the needle bar.
The most common reason why sergers won`t chain is because they are improperly threaded. You should also check that the needles are not twisted or inserted too low.
The lower looper thread could be breaking due to the threading of the machine. 1. Make sure the unit is threaded correctly. – When threading the lower threading lever, make sure the thread is just laid to the side of the lever and not threaded through the lever, click here(Opens in a new tab) for instructions.
Loopers (4): A looper is a small lever inside the serger that has a thread hole (similar to a needle) at the end. Rather than penetrating the fabric, the loopers create thread “loops” around the fabric raw edge. Most sergers have an upper and lower looper that move in tandem with the needles to form the seam.
The Upper Looper produces the stitch that lays on the right side, or top of the fabric, and the lower looper provides the stability for the stitch. Together the upper looper and lower looper secure the stitch at the edge of the fabric after it has been trimmed by the blade(s).
– Check to see if your upper tension is too tight. Standard tension setting is 4. – Your thread could be caught on something between the needle and your spool of thread if so, your thread will be too tight for the needle to pick up the bobbin thread. – Make sure that the upper thread is threaded properly.
Looped stitches are usually caused by improper tension. If the loop is on the upper side, it may be corrected by loosening the top tension or by tightening the lower tension. If the loop is on the under side, it is usually best corrected by adjusting the upper tension.
When you pull the needle out of the fabric, hold the needle at the `bottom`, opposite of the pointed end (of course), where the thread is going through the eye. If you hold it there whenever you are pulling the thread taut, the thread will not pull out.
The best sergers can last a long time while offering convenient features, such as color-coded threading guides to prevent thread mix-ups, easy-to-use controls, clear instructions and rolled hemming to produce clean, professional-looking hems.
Lack of tension on the upper thread
However certain you are that the problem with the machine is most likely due to a huge tangled mess of thread in the bobbin underneath the fabric, the most common reason for the jamming is usually the lack of sufficient tension in the upper thread.
A disengaged clutch, broken drive belt or internal drive gear failure can prevent the needle from moving. Engage the hand wheel clutch if you have it disengaged for bobbin winding. If the needle won`t move with the clutch engaged, unplug the sewing machine and check the drive belt.
There are three main types of serger, categorized by the number of threads used for each operation. A 2–4 thread serger makes a two-thread overlocked edge, a 3–4 stitcher uses three or four threads, and a five-thread serger uses three threads for the overlocked edge and two for the seam line.
Top thread tension is controlled by a dial on the machine`s thread path. So make sure the thread sits correctly between the tension discs when you`re threading your machine. If it doesn`t, then the machine won`t be able to sew properly.
If the bobbin thread was incorrectly threaded, the upper thread may be too tight. 3. Reduce the tension by turning the upper tension control dial to a lower number. If the upper thread was incorrectly threaded, the upper thread may be too loose.
The upper thread tension could be set too tight. Set the tension to the best thread tension setting or less. Make sure the spool of thread is installed correctly using the correct size spool cap for the size of spool.
Pass the needle through the stitch line where the elastic loop was originally secured, then back through the base of the elastic loop, at least 6-7 times. Don`t pull the thread tight; leave a loop to tie off the thread. Insert your needle through the loops, then pull the thread tight.
Use a double thread or even embroidery floss of 2 or more strands. Using a needle, secure the ends to the fabric and come up through to the right side. Make a starter loop and finger crochet along the thread until the chain is long enough for your corresponding hook. Pull the thread ends through the loop to knot.
Push the tip of the thread through the eye of the needle, and pull it through until there`s a generous tail. To tie a knot, loop the end of the thread around your finger, then roll the loop between your fingers 2 to 3 times. Pinch the rolled thread between your fingers, and pull the thread tightly to finish the knot.
Side cutter foot vs Serger
A side cutter foot will make your regular sewing machine work as a serger without having to spend hundreds of dollars, so it`s the perfect alternative if you are on a budget or have limited space in your home.
Polyarn is a premium “woollie-like” texturized polyester thread. Polyarn has excellent elasticity, recovery, and flexibility, which makes Polyarn the top choice for garment construction when sewing on a serger. Because Polyarn is 100% polyester, it has a higher heat resistance than woollie nylon threads.
Here is what happens: The cutting knife is a visual guide as to where the fabric needs to run into the serger. Without the knife in place once fabric is moving through the serger, it can easily drift too far into the moving upper and lower loopers.
Jammed Machine
As dramatic as it may be, jamming is a very common problem for a sewing machine. Your first step toward a remedy is to remove any fabric you were trying to sew. This may require gently tugging at the fabric and lifting it enough that you can snip at the threads and pull the fabric free of the machine.
So what causes a serger needle to break? Some common reasons serger needles break include: using the wrong needles, threading the machine without raising the presser foot, having a loose needle plate, and pulling the fabric through too forcefully.

Kenmoore Intellivac w direct drive suddenly started making internal sound like something was stuck. Hose is clear, and sound is made when hose is detached from main unit. Vacuum sounds find at lower pressure, only makes sound with bag door closed and/or placing my hand over the end of hose.
ANSWER : Shut off the vac and open container and remove the bag. Try dropping a coin into the hose, then raise up to see if it falls thru to the bag area. If it does check the throat of the vac where the dirt is sucked upward to dump into the bag itself.

I had to remove the needle, now my needle won’t stay in. When I tighten the needle clamp screw, the needle slips out. Am I missing a part on the end of the needle clamp screw?
ANSWER : I’ve had this happen a few times. It’s usually because I need to loosen the needle clamp screw a little more to make sure I’m getting the needle PAST the screw and far enough up in the channel so that it can be caught by the screw. I hope this works. If it does, please let Fixya know by rating my solution!
.Good luck and happy sewing.

High pitch My Hoover fusion vacuum cleaner began making a high pitch sound that makes it very annoying to vacuum. I cleaned all the things I could clean. I even cut out all the hair that was entangled in the brushes. Any idea what is causing the sound. It sounds like an siren is going off.
ANSWER : The Hoover Fusion has design flaws in the motor, including a metal plate that is too thin to contain the forces acting on the motor, particularly the constant strong tension from the drive belt, and a plastic plate that is attached to the metal plate by two screws that gradually loosen over time. Assuming the filters and canister are clean, a high-pitched noise coming from the motor indicates it is about to fail as a result of these problems. You can replace the motor after it fails, but the problem will eventually occur again. For those very mechanically inclined, when the motor first starts making the high-pitched noise, you can dismantle it and tighten all screws.

I have a Pfaff 7570 … having a problem with the upper thread making a small loop just above the fabric by the eye of the needle, just before the tip of the needle is piercing the fabric, the stitches that produced are properly formed with the right tension, but the loops get in the way sometimes and I know it never used to do this before.
After reading the service manual I’m suspecting the “thread check spring” is not functioning properly.

Sounds like the beater bar hits the front plastic makes a loud awful noise
ANSWER : Hi Cathy,
Your DC33’s brush control is designed to make a ratcheting sound to warn you if something is jamming the brush bar. You should be able to resolve this by making sure the cleaner head is free of any obstructions, and removing any threads or hair from around the brush bar. For guidance in doing this, please follow the steps shown in our online Support guide:
This should resolve the issue, but if you’re still concerned about the machine after following these steps, please give us a call on 0800 298 0298 (UK), or 1-866-693-9766 (US), so we can provide further assistance.

My Dyson CDC14 Animal just started making a wierd sound coming from the rotating brush area. I already cleaned around the brush, sounds like a fast rattling sound.
ANSWER : Hello,
Something could be jammed, or not rotating freely, maybe an improper alignment with the brushes, or a blocakage within them. Try to re adjust the brushes 🙂
