Cooking on Traeger - Need Help

[spiffy]

I need help from someone who uses a Traeger grill. I followed exactly someone's recipe who made perfect ribs (smoked for 2.5 hours, then 325 for 1 hr 20 minutes). The side down was burnt. Actually, no matter what I do, and no matter what I cook, the side that's down always gets burnt. I don't know why and I don't know what to do to prevent my food from getting burnt. Can anyone help. I don't know if I spoke longer or put the heat up higher and cook a shorter amount of time, or make it lower and cook for longer. No matter what kind of meat, the side down always burns. I'm open for suggestions.

Thanks.
