Repair Tips for Husqvarna Viking 6440 Sewing Machines

By Kim Sarah ; Updated September 15, 2017
Sewing machines are mechanical devices that require repair and maintenance.

Husqvarna makes a series of sewing machines. One of them is the Husqvarna Viking 6440. Like most other models and brands of sewing machines, the Husqvarna Viking requires regular maintenance and occasionally some repair work. This is not something that requires a professional. Most repairs can be done at home in just minutes. Also, supplies can be found in most craft stores, either online or at brick-and-mortar locations. By completing repairs on your own, you can save time and money.

Oil

If parts of the Husqvarna Viking are jammed, they may need oil. Sewing machine oil can be purchased at almost any craft store. It comes in a small squeeze bottle that will allow you to dab oil into the tight interior moving portions of the sewing machine. While doing this, it is important to focus on areas of the machine that come into contact with one another while moving. This is a common area for jams and sticking to occur.

Needle Replacement

A dull or broken needle in the Husqvarna Viking will prevent the fabric being sewn from being properly punctured. Therefore, the thread will never correctly stitch through the fabric. New needles can be purchased at many craft and sewing supply stores. Removing the old needle and inserting the new needle in the same place will allow for proper sewing to once again occur. This same repair or replacement is also handy for a needle that may be incorrectly sized for the Husqvarna Viking. Be sure to purchase the correct needle based on the machine's model number, which can be found on the machine itself or in the owner's manual.

Wire Repair

Wire with coating that is worn or torn can lead to sparking in the machine. This can also lead to electrical shorting and safety hazards if the wire is exposed to moisture. The machine can completely stop working if the wire is visible. Wrapping these areas with electrical tape is a way of restoring coating on the wires. Electrical tape can be found at most hardware stores. You will not have to use anything specifically made for the Husqvarna Viking. This is also more affordable than having the entire machine rewired.

Bobbin Replacement

Replacing old, worn or damaged bobbins will allow the Husqvarna Viking to run smoothly once again. The bobbins are made of a thin metal and are responsible for holding some of the thread used in the sewing process. Since they are moving while sewing is taking place, any small bend or worn area can throw off the machine and lead to uneven stitching, missed stitches or jams. Bobbins can be purchased at many sewing supply stores and come in a variety of sizes. Be sure to purchase bobbins that will fit your Husqvarna Viking model.
