My traeger is not getting hot. When I start it, it does warm up. I can see the hod rod glowing and the pellets are feeding into the box and burning. The problem is that even on high, the traeger doesnt get all the way hot...could the auger be turning to slow?

According to Treager FAQ

"I've been noticing that my grill temperature keeps dropping lower. What is the problem?

You need to "true" your auger. To do this:

Run the unit out of pellets.
Remove the allen screw and nut out of the auger and motor shaft.
Try spinning the auger shaft over the motor shaft. The auger shaft should spin freely over the motor shaft without binding.
If the auger binds, loosen the 7/16th inch bolts on the motor bracket and move bracket until you can rotate the auger shaft over the motor shaft. Then re-tighten 7/16th inch bolts. Make sure auger shaft still rotates over motor shaft, or repeat step 4 again until it does.
Reattach auger and motor shafts using the screw and nut which you removed in step 2."

If your treger wont get hot like when new, clean the fire pot and check for holes burned through, making for poor air flow, i had that problem.
