I'm learning by trial and error, but mostly error on my part. I assumed that since the temp was fluctuating sometimes 30 degrees above my set temp (210 instead of 180) that it would be too risky to increase the heat to 200 like others have, in fear of rendering too much fat. So I sat and watched TV for the evening, eyeing the 3D thru the balcony window. It's been 11 hours now and it just hit 140 internal temp. At this rate, the meat probably wouldn't be done till the middle of the night, so I pulled out the cold smoking plate (that I probably should have removed a LONG time ago) and dialed the temp up to 200.
Holy cow! Did I just catch it that you were trying to get the temp up to 150,
with the cold smoke plate in place????? If so, this explains a LOT about your temperature problems! You can NOT attempt to smoke meat, by internal temp (probe) with the plate in place. The controller can't figure out what's happening in the box because you are blocking the heat to the temp probe!
The plate is for
cold smoking only. This means short bursts of heat, to get the chips smoking, and then heat OFF! The idea is to keep box temp as low as possible, and add smoke,
not heat.
You don't need to autotune, for this issue, you just need to not try and hot smoke with the cold smoke plate in place. Also, it you had your temp set to 180, looking for a meat temp of 150, I am amazed you didn't damage your element. As I said, you fooled the probe, and I bet that sucker was working overtime, trying to get the box up to 180!
Lesson learned, my friend!
