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.
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
