I have a 6039 with four button panel. I reset my settings back to factory accidentally and can't find the forum I use to use. I need to increase my feed rate. Any other tips for this stove would be appreciated. Don't seem like I get very good heat from it. I clean thoroughly. The air coming out, measure in the center with oven thermometer only reads 200 and stove is running on 9. Thanx for any help!!
