rona,I tried your candle trick it worked, stove ran as long I heated the thermocupler.once flame got going i reinserted it in tube. But when I put side cover on stove shut down. I was pushing thermocupler into far inside tube with side cover I bent thermocupler and glued it in place so far so good. I took feeder wheel off and noticed round threaded flange wasn't tight, I retightened seems to be feeding corn better. Hoping this fixes the feed problem i'm having, as of now my feed rate is 4+ and exhaust is -1. Also have lights 1&7 flashing will pull and check fuses tommorrow thanks for help
