I loaded half with Apple dust and half with Hickory, lit both ends to where I had a very small red glow and put it in the cold MES. Set the MES for 225 and left for 30 minutes. Outside temp was in the 30's.
At that time the internal temp was about 180*, I opened the door to make sure the AMS hadn't gone out. Instead of going out I had flames coming up from the entire AMS box. I covered it with foil to try to slow it down but it was burned out within the next half hour.
What did I do wrong? Any suggestions?
