Thanks for the reply! Might be something to take a look at.I have an MES30 from probably 15 or more years ago and used to have that problem. I discovered during warmer weather, the element would not come on as often and the chips never really got going, and during cooler weather I would go through much more. Apparently the insulation is quite good.
For a long time I only ran the smoker during cooler or cold weather. I discovered the mailbox mod and have been running the smoker any time of year with much better and more consistent results.
I don’t know anything about your smoker, but the solution may be something similar to the mailbox mod, which is basically just external smoke generation (pipe it in the smoker) and only use the smoker for temp control.
