At present, pellet grills are mainstream products, with pellet refills filling the market versus having to find timber, sticks, and charcoal to start a fire (since these pellets are made of sawdust, it’s easier for them to cast fire and completely combust into smoke with minimal residue). Old school pit masters dislike this product mostly because it’s too easy to use, like a microwave versus an oven.
I got my YS640 for a combination Father's Day/ Birthday gift and regardless of whether it's grilling or smoking beef, pork or chicken the results have been outstanding. I can hardly wait to break out the turkeys for the Holiday meals. The direct grilling grates leave a steak with beautiful grill marks and the use of the fruit wood pellets along with quality steaks have made for some incomparable meals. As for quality of the smoker itself, I have sons-in-law that are already jockeying for position to try to be the next to have the YS640 after my demise - - - and we're figuring that won't be for at least 20-30 years!
In smoke mode the controller is no longer controlled by the thermometer, it merely switches the pellet feeding auger on and off. On time is 15 seconds, off time ranges from 45 seconds at P0, to 165 seconds at P15. Temp and smoke are controlled by the duration of off time: the auger always runs at the same speed. More smoke is produced at higher P settings and lower temp settings because longer off times allow the pellets to smolder. At P0 in smoke mode or "High" in cook mode the auger replenishes the pellets at a faster rate, creating more flame, less smoke.
I have used mine Traeger 15 times and it hasn't worked once. I will not hold the temp within 15 degrees as they state. I can set mine to 225 and will go between 180-370. It also consistently shutting itself off with the same error. I have spoken to cust service 12 times and they are worthless. I have had new controller sent and other various parts. I have been on the phone with them for hours. I always have to take my meat off and finish it on my Weber. They refuse to send me a new one. They still demand to go back through the same damn steps as the last 12 times to debug it. Never again. If you see my post on Craigslist, don't buy it, it's a lemon that Traeger will not support.
Most pellet smokers are wood-burning ovens: great for ribs, turkey, brisket, and pork shoulders, but not so great for grilling steaks and burgers. The FEC PG series was one of the first lines of pellet burners to offer a sear station, a cast iron cooking grate right over the fire pot where the wood pellets burn. It isn't the best setup for searing, but it's better than most other pellet searing schemes. The real beauty of the Fast Eddy's design is that it produces meat with a deep mahogany finish, much like a competition-grade offset smoker. It also has two upper-level heat zones, for a total of four distinct temperature zones.
