I am still loving my second owner KBQ, but wondering if the temperature tolerances can be tightened. I have a new digital thermometer that is showing the wide swings, that are fairly rapid up and down.

Ambient air temp is now 63 degrees, started the cook at 5am and temp was 37 degrees and the pattern was the same.

Would it be slower with a welding blanket wrapped around it? Do I need a new control box? Any Other suggestions?
