A few years ago my wife saw one of these and before you knew it I was installing it in the house. It's pretty. Operation has been intermittent. I have tracked the problem down to the on/off switch on the side. We do not use a wall stat or a fan on it. it is a simple on/off operation. I am on my third of these switches and apparently they are affected by the heat generated by the stove. I just wrote a letter to VC, but am curious what you all see on these. What is the fix?
