the machine seems to be workign but no fog is coming out. It makes noise, gets hot and seems to be pumping.
Is it a fog machine or a smoke machine? A fog machine is a large barrel you fill with water, put dry ice in the basket, and there is a blower on the cover. A smoke machine is a small box that you put a special solution in that makes the smoke. Did you put in the solution or get dry ice, whichever your machine needs?
