Nebraska Smoker

Hey I am a rookie traeger grill cooker.  I have had it for a couple years but not an experienced griller by NO means!  I am from Nebraska and love my huskers and love my beef.  Anyways on my traegger all of sudden my damn auger keeps running constantly!  It never shuts off it just keeps churning out the pellets.  So when I set it to smoke ....... well it does for a little bit and then it just keeps getting hotter and HOTTER!  I am guessing I need a new control panel?  Thanks in advance!
