OK so as most of you know I use my MES a LOT. I noticed on a pastrami smoke yesterday that the gill level temp was 25° higher on the 2nd from the bottom grill than what the MES was set for. In the past it was always within a few degree's of my digital probes. This morning I decided to check things out since I have a smoke on a large t-bone roast today. After pluggin it in, and turning it on, I saw that the MES thought it was at 32°. Ambient air temp was 65°, so I rigged up two digital probes. One at the vent and one at the grill level (sencond from the bottom is where I typically cook) I started with setting the MES temp to 110° and whithin 15 minutes both my digitals said the temp inside was about 200° and the MES said it was at 80°. At this point i am panicking since I wanted to do a cooler smoke today. Well after another 15 minutes the temps on the probes remained at about 205 and the MES said it was at 110. I set the temp one the MES to 150, and let it go another 15 minutes. Now the MES said 150 and probes 225. Long story short I kept playing with this and it looked like the MES probe takes longer to catch up. After an hour and a half I have a 30 degree split between MES and probes. Usable but annoying. Anyone else see this kind of lagging? Is this a pre cursor to a total failure?
