No, It doesn’t shut completely off. But you can hear it when it is calling for more heat. Typically you hear the fans and when it reaches temp they shut off. Mine was set at 185, You hear it kick on and it goes up to 200 roughly, then the fans kick off and the temp goes down(hopefully). That would be normal. However it doesn’t always kick off. Sometimes it goes up as high as 450 with it set at 165. This is totally a Traeger issue, absolutely nothing to do with ambient temp. I actually have texts from Traeger where a CS rep admitted that they know they have temp issues big time, I snap shot the texts and sent them back to them, thats how I got my money back! It is a huge known issue with Traeger. I since purchased a different grill, sits outside and even on a 95 degree day it holds + or - 5 degrees, like its supposed too. Ambient temp is a bullshit excuse, just like changing the parts on a brand new grill.
