Congratulations on your Traeger purchase - even though you've had some trouble right out of the box. Once that's square away, I know you'll love your Traeger. There doesn't seem to be many Traeger lovers here so I really enjoy speaking up in support.
Having said all of that, one word regarding 'maintenance'. If you live in a damp, high humidity part of the country (the Pacific Northwest, in my case), pay attention to the operation of the auger. I have just spent the better part of an afternoon drawing out the auger to clean a frozen auger. It was apparent as I slowly drew it back out through the hopper, clearing 'sawdust', not pellets, out of the passageway, that moisture had caused the pellets to swell up, convert to sawdust and completely freeze the auger. And, before I identified the problem, all I was doing was compressing more sawdust against the blockage creating a virtual concrete plug.
So now, I try to empty the hopper (you need to anyway if your next project uses a different flavor) and run most of the pellets through to the burner. I know it takes a minute or so to 'reload' the next time but, for me, it's worth it not to have to taken the freakin' thing apart again.
I have the older model 075 with the round hopper that needs the interior sheet metal dismantled to get at the auger and the motor.
Anyway, good luck. Keep your posts coming!
