Im hoping you guys can help me. I have a MES model#20071415 that I got last year. It has the digital panel to control temp, the meat probe and the vent is on the side of the unit, near the top. Anyway, my problem is that I cant get it to produce enough smoke. I can put pellets or chips in, and the first load burns just fine, making good smoke. But after that, anything I put in there just turns black and does not smoke. It seems the only way to keep it smoking is to open the front door, pull out the chip tray, empty it, put it back in, close the door then add more chips. All of this would lose heat, and just not be efficient, especially since the unit is designed to have chips loaded thru the side. Otherwise I think it works pretty good, I just need more smoke and smoke flavor. Anyone else have this issue? Can anyone help?
