I just got a tell tru last week cause I figured if my maverick ever died during a cook I'd be up a creek. The gauge that came with my smoker sucked. So I did a boil test on the tell tru to be sure and it was right on 212.
Well when I put the tell tru on and started my smoker this morning, the maverick is almost 70 degrees off??? It is positioned relatively close to where the tell tru probe is too. I noticed my maverick getting funky during my last smoke over Memorial Day, but can't imagine it's that far off. Did I maybe knock the calibration of the tell tru off during installation? I tried not to tighten it with the dial and just with the nuts.
