I got my pro 575 about a month ago. From the beginning I was having problems with everything taking double the time to cook. I called Traeger and they immediately sent me a new rtd probe. I put it in and it was the same problem. I went and got a new oven thermometer and saw that my grill was anywhere from 100 to 125 off. I called Traeger again and they told me to just turn the grill up another 100 degrees because this is how Traeger grill are ......really. I went back to where I bought the grill and was told I needed a return code from Traeger in order for them to take it back. I was trying to support a small local hardware store. I guess this was a mistake also. So, I called Traeger yet again and asked to speak with a manager. She told me that an external oven thermometer is insignificant and that if my controller says it’s at 450/350/250 degrees than it is and that she can’t troubleshoot a “fully functioning” grill. I am beyond frustrated.
