Sorry for the incomplete information:

Yes the switch is turned on.

I have not allowed the switch to stay in the on position, DVD instructions are pretty clear on that.

I put the recommended amount of smoke drops into the stack.

Still nothing, sure would like to my Grandchildren to experience the smoke as they have all asked about it.

Thanks for all the replies so far.

Finally ordered and received the Night Before Christmas set, been wanting one for quite some time.

Trouble is I can't get the smoke box to work at all.

Checked the forum but was wondering what to check first before working on a brand new unit?

Thanks for any input.
