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!

I recently purchased a a Smoke Hollow pellet grill from Sam’s. Seems like quality is good and it was recommended by a friend. Temperature control has issues. I called for customer service a couple of times and they sent a new thermostat. Still can’t get temperature to to hold at setting. Am I missing something? Told to start and let preheat for 10 minutes and then move to desired temperature. Tried setting new thermostat at 190 and let it go for 15 minutes and it was back at 230 when I checked it. Any suggestions?
If you live in an area where wood furnaces are used (not like down here in FL where a few heat strips will do the trick), you may also be familiar with pellet furnaces. In short, pellets compressed from sawdust and wood shavings fill a hopper and are then fed into a burn pot using an electric auger system. The auger, which is basically a long screw, delivers pellets to the burn pot based on the speed dictated by the unit’s thermostat. As the burn pot ignites, the pellets burn. Heat then carries through the home via convection (air driven) means, thus allowing air flow and a blend of warm and cool air to maintain steady, even burn temperatures. A heat exchanger separates the smoke fumes from the warm air, thereby warming the room without smoking everyone out.
GrillGrates(TM) amplify heat, prevent flareups, make flipping foods easier, keep small foods from committing suicide, kill hotspots, are easier to clean, flip over to make a fine griddle, and can be easily removed and moved from one grill to another. You can even throw wood chips, pellets, or sawdust between the rails and deliver a quick burst of smoke to whatever is above. Every gas grill needs them.
I have used this cooker at least once a week for two years. I recently had a couple of issues with it going out and was thinking it was having a serious issue. Quite frankly as much as I use it it should be worn out by now. Here is what I discovered. Carbon had built up on the tempeture probe and the grill wasn't getting accurate readings. Suspecting the temp probe I checked it with an external one and it was off 50 degrees or more. I am assuming that the readings were off enough that the grill controller just shut it off kind of a fail safe? 30 seconds with steel wool and we are back in business.
Even and fast cooking – this is the common feedback of the new and past users of this pellet grill cooker. Although some of them would say that the temperature is inaccurate, they can still manage to adjust everything well by means of its digital temperature controller. Additionally, you may need to add more pellets if you will set the temperature on a high setting.
I don’t know why these cookers are referred to as grills. By definition they are not grills. Grilling involves cooking with direct heat and none of the pellet cookers I’ve seen use direct heat; they all use indirect heat. They are more accurately described as smokers/convection ovens. For me what this means is they’re useless for cooking chicken since I like my chicken cooked with crispy/burned skin. I’ve done some experimenting to get the skin to crisp up but always end up with leather skin. They have their place in outdoor cooking but grilling ain’t it. I just bought a Green Mountain and I’m still debating if I’m going to hang on to it. Shame on me for not doing more thorough research first.
Pellets not Lighting: It’s a simple issue. There is a problem either with the connection of your lighting rod or a damaged system. Repairing the wiring, if that’s where the problem is, might be a little complicated for most. So, for the average griller, the best and the easiest option is to replace the lighting mechanism altogether. When you buy the replacement part, it will come with a detailed instruction manual that anyone can follow.
Hey Jim, first – thank you for commenting on this post! As you probably know from reading the contents, pellet smokers are a great choice for set it and “nearly” forget it BBQ. Of course, you’re not going to get the same smoke profile with “pellet poopers” that you are likely getting with your other smokers. That said, the smokers listed here are all going to hold temp very well – even in lower temperature or windy weather. I do see instances where temps and wind effects pellet grills, but solutions including a fireproof blanket over the top of the smoker seem to mitigate things well enough.
I don’t know how many meals I cooked on that thing, but it’s been enough to make me a hero and de facto camp chef among my friends. I seared up a tri tip large enough to feed four hungry kayaking buddies at the Salmon River Festival one year, then covered it with foil and cooked it on indirect heat for one of the best steaks of my life, which we happily consumed in the middle of nowhere. The grill also perfectly charred onions and peppers to deliver a mountain of chicken and beef fajitas to a crowd of ten. I still get compliments on that one. 

Thank you so much for the kind words! I think you would be very happy with a smaller pellet grill / smoker. The wording changes depending on how you are using the device. For instance, if you are cooking at low temperatures you will get a stronger smoke profile then if you burn a pellet smoker / grill at its higher temperature range. One thing you could do for steaks is cook them at the higher range thus being able to get a sear much like you would on a direct heated Grill service, for instance on your Weber. Another option would be to cook the steak in the reverse see your method, by bringing it up to temperature at a lower smoker setting and adding some smoke flavoring that way, then removing it and bringing the smoker up to its higher settings so you can finish off the steak with some of the effect you would achieve on direct flame. I normally do this by bringing the steaks up to about 15 degrees below where I want them to finish. Then, I finish them off at the higher temperature to where they are about 5 degrees below my target. This usually means a few minutes on each side but I use a Thermapen to be sure.

It makes party hosting, as well as small crowd-feeding a breeze! Pellet grills are easy to use because they often come with easy temperature controls (along with other variable facilities depending from grill to grill), making it ideal for beginners who do not have prior grilling and cook-out experiences. A pellet grill is the answer to every cook enthusiasts who love to cook, but lack the knowledge and experience of skilled pit masters.
Although I marked price high. I would buy it again, tomorrow. I was a novice. I had never smoked anything when I bought this. It is amazing and if you asked my friends and family I should have opened a bar & grill. It's grills better than any gas grill u can buy. The YS640 only gets better with time you get good at using it. It's the best cooker on earth. If your considering paying over $800 for a cooker. Spend the money... you will not regret it. My cousins have Traegers.. and they smeared by them. One weekend at my cabin one has ordered his the other don't have the money yet. I have used it a minimum of 2 days a week and have already got my money out of it by not ruining meat. The guys at Yoder have a monopoly. No one makes a cooker that could stand up to it. THANK YOU YODER. YOU HAVE MADE SOME GREAT HOLIDAY MEMORIES FOR ME AND MY FAMILY. Remember if your on the borderline don't know if it's worth a little more. By the 12th month of owning it. You will look at your wife or girlfriend and say "I'm so glad I spent a little extra and got that. It's beautiful.

Most grills feature a primary cooking area (the main grate) and a secondary cooking area (additional racks). In a pellet grill, there’s less difference between the two grilling areas because it mainly cooks by indirect heat, so the temperature is the same throughout the grill. It’s best to pay attention to a pellet grill’s total cooking area because it is the sum of the primary and secondary cooking areas.
