I have a new MES with bluetooth and am having a problem with it getting too hot. I have the temp set at 225. My bluetooth app shows the temp set at 225 but the smoker temp has jumper over 350. I went outside to check the smoker and adjust the temp, it showed the temp set to 899 degrees. That is supposed to be impossible because the unit is supposed to be capped at 275. Does anyone have thought on why this is happening? It has happened 3 times on my first brisket so far, I am about I am about 9 hours in so far.
