There is no worse feeling than starting to work only to find your machine is uncooperative or broken down.  It could be snapped needles, broken or tangled threads, or even skipped stitches, which can end up giving you a frustrating experience in what you fancy doing.

Luckily, serger troubleshooting can help you sort most of the issues without taking your machine for expensive repairs. To help you manage your serger correctly, we have gathered some of the common sewing machine problems and the way to solve them to ensure you troubleshoot and resume your project from where you stopped it.

Problems with Tension

A serger is a useful tool when it is in perfect working condition to sew garments. It also performs other tasks apart from knitting. Change in tension on your serger can create different finishes and stitches. Even though a serger is a wonderful tool, the experience can be frustrating when the tension gets out of whack. Fortunately, there are ways you can troubleshoot it and continue working. Some of the common tension problems include problems with fabric puckers, loops on the underside seeming to pull apart, the lopper threads getting removed towards the right side of the fabric, and the upper lopper threads getting pulled to the underside of the fabric.

How to solve it

Thus, it is important to know how to get a balanced serger stitch and know how to fix them if they aren’t serving you.

To avoid experiencing the problem in the future, you will need to be familiar with adjusting tension for various color treads and each needle lopper. That helps to know the treads in each stitch. Changing the lopper tension determines how much thread will be released from each of the stitches. Loose lopper offers longer/wider stitch. You will need to tighten the lopper tensions to get a narrow stitch.

For fabric wrinkles, you can solve the problems by loosening this needle tension. For the loops on the underside seeming to pull apart, you solve it by tightening the needle tension.

For the lopper threads getting pulled to the right side of the fabric, you can solve it by losing the upper lopper tension; alternatively, you tighten the lower looper tension. For the upper lopper threads to get pulled to the fabric’s underside, you should tighten the upper lopper or loosen the lower lopper tension.

Problems with Stitches

Problem with stitches is also common for sergers, and the needle happens to be the main culprit anytime stitches skip.  The need could be broken, or you be using the wrong type or size.
