I am one of the ones who have had many of the problems associated with the Timberline 1300's. Soot, burn back, flame outs, failure to start, ash donuts in the fire pot,smoke from the hopper etc... I have owned it since May and I think that last night I finally was able to get it to run correctly. Traeger has been great this whole time and their customer service has been top notch. They replaced everything on my smoker with the exception of the body (lid, gasket, fire pot, auger, igniter, hopper, controller). When basically everything was new, I ran it and there was a mysterious noise that sounded like a solenoid buzzing. Traeger was ready to send me a new grill, but I was able to diagnose the problem to a loose screw that was causing the blower fan to vibrate. I'm replacing the screw today and that should take care of the issue. It shouldn't have taken so long for my unit to be fixed, but I had a very busy summer with work and traveling so there just wasnt time to tinker with it.
I think Traeger has now addressed most of the issues that plagued them in the beginning with the 1300's, with the exception of Super Smoke mode. I have heard it still produces soot for some people.
Here are my thoughts on the whole deal:
1. It seems that Traeger primarily focused on creating the Timberline 850 and the 1300 was an afterthought. They probably thought that they could just mimic the settings from the 850 and didn't take the differences in cook chamber size, air flow, etc into consideration. Either that or they knew they had issues with the 1300 and that is why it was released after the 850, and they chose to release it anyways.
2. They need different firmware for their controllers based on model (850 or 1300). One size does not fit all. A fix released for the 1300's messed up the 850's. Maybe they will do this in the future, but I think it is needed.
The whole deal has sucked from the beginning, but it seems to be getting better. It is reminiscent of what Yoder went through when they first came out. I am not sure I can really recommend the Timberline series just yet, but they seem to be making progress.
