​Trust the Sewing Machine Repair Experts

Thread jams, often called “bird nests,” usually occur due to:

• Incorrect threading of the upper thread or bobbin.
• Improper bobbin winding or placement.
• Lint or debris caught in the feed dogs or bobbin case.
• Tension imbalance between the upper and lower threads.

To fix this, rethread the machine (both top and bobbin), clean out the bobbin area, and check that you're using the correct bobbin for your model. Adjust thread tension gradually if needed.

If your sewing machine doesn’t power up:

• Make sure it’s plugged into a working outlet and that the power switch is turned on.
• Check the foot pedal connection and power cord for damage.
• If the motor hums but the needle doesn’t move, the handwheel may be disengaged or the machine may be in bobbin-winding mode.

For older or heavily used machines, a burned-out motor, faulty foot pedal, or internal electrical failure might be to blame. These may require service by a qualified technician.

Skipped stitches can result from:

• A bent, dull, or incorrectly inserted needle.
• Wrong needle type or size for your fabric and thread.
• Incorrect thread tension.
• A timing issue between the needle and hook mechanism.

Start by replacing the needle with a new, properly matched one. If skipping persists despite correct threading and tension, the timing may be off — a more complex issue best handled by a technician.
