I’ve been having the temp issues. After talking to Traeger numerous times, Instead of waiting for RTD’s to get back in stock in 3 to 4 weeks I took the grill back to dealer and they took RTD out of another grill they had in stock and put it in my grill. Carried grill back home. New RTD helped it maybe 10 degrees, called Traeger and told them that new RTD didn’t fix it, was still about 90 degrees colder than controller showed. They finally let me talk to supervisor who told me they had come out with new firmware update. This was on Thursday. He said they were starting to push updates out and he would have them go ahead and push an update to mine within 24 hrs. Update showed up on grill sometime late Friday. Fired up grill this morning and it is within 10 or so degrees of my thermometers I have been using to check inside temp, so looks like this firmware update might be the fix to our Pro 575 problems. Previous firmware on this grill was 01.01.01. Now it shows firmware as 01.01.02 . Hope this helps everyone.........
