I tried to do the initial burn off but after 4 hours it never got above 200 F. Checked all the functions and I’m doing everything as instructed. I dunno if the thermostat is bad on the door but there could have been a much better way to design this smoker. I’m running it now with meats in it and have been watching it for two hours now on the highest temp setting and the gauge says 190 F. I’m a little disappointed in this product.
