Does an Open Window Hurt a Computerized Machine?
 

The title is pretty much my question.

I have been leaving my sewing room window open at night, but wonder now if it would effect my Baby Lock Crescendo? Moisture coming in?

High humidity and computers are not a good mix. Check your local weather report for the humidity in the air.

Humidity and or dust would be my only concerns. If you don't have either, enjoy the fresh air!!

Those would be my concerns also. We never leave our windows to the sewing rooms open at night as they are on the lower level. I have never heard of anyone stealing a sewing machine, but a person can't be too careful.

Yep, humidity can cause circuit board corrosion. And as mentioned, dirt, dust and grit is another issue. This article mentions open windows: http://www.threadsmagazine.com/item/...nance/page/all. If humidity isn't a problem, just tossing a cover over it for the evening can help. I have to do that anyways because of the furry ones lol. You can even make a really cool one yourself (I bought a personalized one because I had just started and wasn't at that level yet!)

Well where I live, if it's humid outside, it's humid inside whether the windows are open or not. I'd be more concerned with the condensation (aka dew) that may form on rapidly cooling surfaces like metal during the overnight hours. That's really the only difference between open windows in the daytime and open windows overnight, that and potential two or four legged intruders. Humidity and dust are going to be there with open windows night or day.

I would cover definitely when not in use. Perhaps a cover with a plastic insert to stop some moisture or just rain.i do know that with cold weather berninas aren't happy machines. How? Friends who put their machines in the car the night before a class always had problems at class in cold weather.

I have never given this topic any thought because I don't live in where there is much humidity. I do try to cover my computerized Bernina at night to keep any dust particles off of it.

This gave me a good chuckle because my sister is constantly threatening to steal mine one day!

It would be the same as leaving your machine on a porch over night.
