Okay, now I'm really confused, not that it takes much, you've NOT used the smoker? How do you know it's broke?
The blacker,greaser the insides...most of us would welcome.
Here is a search that I did on cleaning smokers, hope it helps. cleaning smoker
Most of us would take a paper towel, wipe down the sides and them put 5ozs of wood in the wood box. Put in a big PB,set on 250*, and cook till 195*. I guess maybe some new folks would just turn it on and see if heat was coming out of the top hole first.
We all just assume these smokers will last a couple lifetimes after using them for many years.
Cleaning just ain't ever crossed my mind,oh well!
