It could be because there is a wire pinched in the covers to look for or a bad L-print circuit board BUT... Because the foot pedal is not jammed does not mean it isn't working correctly. Inside the foot pedal are two big springs that lift up what is called a carbon pin housing (that has a hook that attaches to the top of the footcontrol)that has carbon contacts attached to it. When these are lifted up the machine is stopped. When you press the footcontrol down it presses the contacts down and speeds up the machine. So somehow this carbon pin housing hook has become disengaged from the footcontrol and the contacts are sitting at the bottom allowing your machine to start at full speed. If your not afraid to fix this yourself heres what you do... 1. With a small screwdriver go through the tiny hole on the bottom of the foot control and adjust the potentiometer. (the potentiometer will only turn 3/4 of a revolution.) 2. Hold the foot control while removing the 4 screws and the two bridges. 3. Carefully release the housing (spring pressure) but do not pull the housing apart. 4. The top and bottom cover are connected by a hook. (if its not broken off) I think this is your problem since most likely the hook has become unattached. At this point though it would be good for you to clean the strips that the 2 carbon pins slide on with a q-tip and remove old carbon residue. Check to make sure the 2 little black carbon pins are not broken. (if they were the machine would not run at all). Be careful not to hurt the carbon pins) 5. To put this back togeather properly... insert the carbon pin housing into the bottom housing of the foot control (if you took it completely out). 6. Insert the two springs 7. Insert the top cover and hold it down while installing the 2 bridges with the 4 screws. to connect the hook follow the rest of the procedure... 8. Press the bottom and top togeather until 2 loud "clacks" can be heard. The clacks indicate that the hook engaged into the latch. 9. Now operate the footcontrol several times by hand up and down. It must be possible to hear clearly the soft clicking of the micro switch. If the clicking of the micro switch cannot be heard repeat step 1. Good luck. Your only next step will be to bring it to a tech or get a new footcontrol. (spendy) Rick.

You need to do a tension assembly test.

mso-padding-alt:0in 5.4pt 0in 5.4pt;

Tension assembly test. To do this test. Pull the thread
through the tension assembly and test it to make sure the tension is working
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.)
If it doesn’t work this way then you probably have a piece of thread or lint stuck inside the tension discs. To remove it, turn the tension to 0 zero and raise the presser foot.Using a small screwdriver, open the space between the discs and spray with canned or compressed air. The stuff should come out. Do the tension test again to make sure you got everything and then try sewing again.

Your machine has a timing problem and should be seen by a technician to repair it.It is possible that there is a loose part also.

SOURCE: I have a quantum cxl.
The needle shaft sticks to the curved arm and won't come down because a piece of plastic, about an eighth of an inch thick had broken from age. It prevented the shaft from staying up on the needle arm. Open the cover, try to stitch decorative stitch and see what I mean. Purchase a package of 4-10 by 1/2 nut and bolt pack. Screw the nut all the way onto the bolt. Using needle-nosed plyers, Carefully bend the curved arm slightly, and place bolt into the hole on the top of the needle shaft. Nut will keep it in place. Lowering the needle shaft using wheel, carefully bend arm back in place. Try decorative stitch. It should work. It does for me.
