Trailblazer Low temperatures overheating, can't seem to get it to stay on low temperatures, any suggestions?

My grill will not hold low temperatures, any suggestions on what the problem is, thanks

Can you describe the issue in more detail?

Assuming it’s not because you are opening the grill lid which will cause spikes, check the feed rate on your auger. Try 3.0 or 30 depending on if you adjust at the controller or on the app.

What part of the country are you in?
Could it be your ambient temp?
It's a little warm in the SW...
