    Praise the Lord its fixed. It's been on for 40min at 250F so now we can have pulled pork tomorrow! Didn't trip two different GFI receptacles. I think it was the temperature limit switch. Replaced the spade and kinked portion of the black wire at the heating element but it still went to...

    MES MB20072816 Not Heating

    Thanks Tallbm. Ive been very pleased with my MES except this mishap. I got started on a thin uninsulated metal smoker and it was an art due to being weather dependent. Hopefully the temp limit switch doesn't break for a while. Thanks again.

    It was the temperature limit switch!!!! Bought a pack of 6 for $7 on Amazon ( KSD301 250v 10a 150c) but I can tell they are Chinese poop because the wire connector came off. Also replaced the connectors for the heating element.. Know of any USA made limit switches or at least better than...
