Just picked up a MES from Academy this week. Rounded controller on top. Vent on top back right. Door hinged on the right. Pre Seasoning tonight. 50 degrees outside. Running heavy duty extension cord. I have an oven thermometer hanging on top rack. Set for 275. Oven thermometer reads 240 and the Meat Probe, which is in the clip, reads 218. From reading the posts around here it seems that these models run hot but it seems this one is running colder then set. What am I missing? What steps, if any, can I take to identify the actual temp and fix any issues? It does produce a fair amount of smoke so I may be worried for nothing. Thanks for your help.
