We purchased a Traeger Jr last summer and have only used it a few times. We opted for this make and model for its size and the pellets. I had my first big success recently with some ribs so now I want to venture on with other meats. Shortly after buying the smoker I bought the digital controller off the net. It was the previous model versus the one they sell today. After doing a short smoker warm up I put the ribs on and closed the lid. The controller was set at 225. I decided to sit and watch the controller for a while and noticed it would fluctuate from 220 to 270 like a yo-yo. I called Traeger to see how much of fluctuation I should experience. They said no more then 10 to 15 degrees. I told them what I was getting and they blamed my warm up method. So before I smoke my next item I will try to warm up the smoker their way. But something tells me it is not going to make that big of a difference when the temps are going up and down after it has already been running for over 2 hours. Is the warm up that important for temp control when you start smoking? The reason for this post is to find out from other Traeger owners if they are having the same problem I am experiencing with temp control? Thanks for your time.
