I am getting min firepot temp shutdowns on my AE, I had been getting them every five hours or so when I was burning straight corn, so I switched to pellet corn mix and everything had been good for a couple weeks until today. I am burning at a -2 flame height and Manual MH. When it happened before, the pot was over flowing with fuel, it was feeding too much even though I was on -5 flame height at the time and it wasn't getting enough air flow because of the overflowing pot. My flame height seemed good with the corn pellet mix at -2, maybe now I need to lower it. Any ideas?
