Last week, I posted in the “Show us what you’re cooking” thread about some issues I was having keeping grill temps stable while grilling a tri-tip. Since I was going to do a couple of pork tenderloins this afternoon, I gave the RT-340 a good internal cleaning (including the temp probe) and fired it up. Outside temperatures are in the low 40s here today. I set the temp for 200F (since that’s where I wanted to start the tenderloins) and let the grill run for 30 minutes to get stabilized.
It was soon obvious that despite the cleaning, the temp swings I experienced last week were still occurring. Temp dropped down to 160F and ran up to 235F—several times. I checked the feed rate and it was at the default 30. Figuring that the low outdoor temps might require bumping it up, I set it at 40 and let the grill run for another 20 minutes. Temperatures immediately stabilized. I dropped the grill temp to LO (180F) and it stayed within 2-3 degrees above/below for 30 minutes.
It appears that the lower outside temps just demanded more pellet delivery to keep grill temperatures stabilized. So, the problem seems to be solved and the marinated tenderloins just went on the grill.
