Hello I have been searching the archives here for an answer and I am sure its here somewhere just cant find. just got my MES 30,.. I want to make jerky and decided to test the unit first..I started at 140, 30 min later no smoke(dry chips)...every 30 I bumped up the temp 10 degrees..after I got to 180 still nothing and lost interest!(glad I didn't have meat hangin!) I did read about bad elements but I just got this thing from qvc you would think it have updated parts by 2014. (model number:20072614 800 watt) Thanks in advance!
