If the unit is in a cold place then I expect trouble. Why this is would be explained by the maker or a science teacher. Let's just say the cold air would cause the amount of moisture in the air to plummet to the point where we should see the unit refuse to use this feature.

Has anyone been able to use Steam Refresh in cold weather? I have an LG DLEX5170 that keeps malfunctioning and giving me error tE2 when I try to use the Steam Refresh. I works sometime and doesn't sometimes. The repair men replaced multiple parts and finally said the drum needed to be preheated. But I've tried that it is still doesn't work. It's been cold here (Washington DC) since I first got the machine last month (Dec 2013), but no colder than people who live up north deal with all the time. Does this dryer's steam functions work for anyone in cold weather?
