Before Christmas I bought myself a new computerised sewing machine. It arrived on the Tuesday and, after taking a quick look at it, I put it away in my room until the weekend. When I tried using it again on the Saturday afternoon, it would not work, making a horrible noise as soon as I descended the needle into the bobbin section with the foot pedal. While the needle was not jammed and could still move freely, the angry noise continued until I turned the machine off. I tried the machine at intervals for 5 hours before giving up. I left it on the dining room table overnight and next morning it was working fine. It worked fine for the next week, when I was using it pretty much daily. Then I put it away over Christmas, back in my room at the foot of the bed. The next time I came to use it, the same problem occurred. I decided not to worry about it but just leave the machine on the dining table for a few hours. Guess what? It worked fine again.
My theory is this: sewing machines don’t like being stored in cold rooms! My bedroom has no heating and is north facing; it’s pretty cold in there. The dining room is one of the warmest rooms in the house. If I keep the machine in there between sewing sessions, there is no problem but, if I return it to storage in my cold room, I have a problem the next time I use it.
Why does this happen? A bit of research on the internet has taught me that modern, computerised sewing machines do not need oiling because they have this grease stuff put in them when they are manufactured. However, this grease can go thick at cold temperatures and so not lubricate the machine properly. This is most likely the cause of the problem when the needle entered the bobbin area of the cold machine. So the lesson I have learnt is to keep my sewing machine in a warm place because it can be pretty temperamental in colder climates!
It is worth mentioning that my research on the internet also reminded me that since it is a COMPUTERISED sewing machine, the computer function can also play up at extreme temperatures too, just like mobiles, cameras and laptops. So there are two reasons to keep them in the warm!
