Hi CanAm99;
Welcome to the forum. Please state what model you have, and also how long you have had it will help.
I guess regional dialect need to be cleared up first.

I was puzzled by what you were referring to when you said misting, after reading the full post I realized you meant what we call in the northeast as drizzle. Also using the term "box" for the generator will confuse members, or at least me.

When someone says "box", we may must likely think you are referring the cooking chamber, that Bradley refers to as the oven, you will see me refer to it as the cabinet.
Hopefully the problem is the fuse. The fuse is located on the back of the generator. You will see a knob, push it is slightly and turn it, it will release and you can remove the fuse. It is a 10amp fuse. You may find it at your local Wal-Mart or other store that has an automotive section. You will have better luck going to an auto parts store. Take the fuse with you, and show them what replacement fuse you need.
