How do I Troubleshoot a White Serger 2000?
The White serger model 2000 is a 2/3/4 thread serger, meaning that it can sew with either 2, 3 or 4 threads depending on the project. The accompanying needle threader for both the left and right needles are just one helpful feature to this serger model. The adjustable cutting width and a threading diagram printed directly on the drop-down front plate make it easy to use. Like most sergers, troubleshooting involves checking the thread and removing any jams, making sure the sewing needles are sharp.

Check the thread path and ensure the serger thread follows the path on the threading diagram. Stitching will become irregular, or even skip, if the serger isn't threaded correctly. When rethreading the serger, follow the recommended order of lower looper first, then upper looper, followed by the right needle, and last the left needle. The threading diagram will be printed on the inner part of the front cover. Pull slightly right, then down to move the front cover and view the diagram.

Replace bent, broken or worn out needles. Skipped stitches will often be the result of one or both needles being dull and rounded at the tips, preventing them from puncturing the fabric. Also, ensure that the sewing machine needles are firmly pushed all the way into the needle cavity before tightening down.

Set the differential feed to a lower setting if the fabric begins to pucker. The differential feed is helpful when joining two very different fabrics since the feed dogs can be set at different settings, but can adversely feed the fabric if not set correctly. Test sew on scrap fabrics, the same as the ones being sewn on. Start the differential feed at the "1" setting, and change it as necessary to adjust for the fabrics being sewn.

Reset the thread tensions on the upper and lower thread loopers, as well as the needle threads. If the thread tension is too tight on the loopers, it will cause the thread to break and the serger will need to be rethreaded, and likewise for the needles. Tension that is too loose will cause extra thread to build up and possible jam around the needle when sewing, or will result in the seam coming apart after sewing. To increase the tension on any thread, move the tension dial to a higher number. To lower the tension, move the tension dial to a lower number.
