Thanks, OF. I'm a tinkerer by nature, and a baseball player at heart (3 strikes, you're out). My third new unit arrived, and it's a "mystery smoker" like the others it replaced, so since the designers can't get it right (by me anyway) I'm gonna give it a whirl.I just dropped it on the bottom corner. I have a two story house so it was no problem finding a 15 foot drop onto the concrete, but after two misses, I put a paper tail on it to fall the way I wanted......
OK, I actually pried the 5 rubber plugs out of the back side and took the Phillips screws under them out. Turns out you don't need to take the one on the hinged top piece out. If you look closely at the photo you can see the screw bosses in the lower corner and under the oven on the left? The fourth is in the shadows upper right.
Open it carefully and watch lead dress putting it back together, it's cramped in there. The hinge is tricky, and a good way to screw it up. Not really much to see, IMO, and it will blow the warranty. Your call.
Good luck.

Worst case, I won't be able to get it back together and therefore will avoid the temptation to vape from it as is. Hopefully, I can figure out -- and remove or negate -- the source of the mysterious vapors.
Thanks again, for the good luck wishes.
