Did ribeyes on my new 700. 225° until IT of 118° when I then set controller to full to heat up my Sear Grates. I could only get to 440°. I've read where some have had the same issue. I said, "Screw it," and put them on the grate any way. As I stood there waiting to turn the steaks, I noticed that I forgot to shut the meat probe port on the side. As soon as I did that, the temperature started rise drastically. I was in it too deep to let it max out, so I went on searing 2 min, turn, 2 min, flip, 2 min, turn, 2 min. The steaks were cooked to perfection with an IT of 157°. I wish the sear would have been better. It probably would have had I figured out the probe port earlier. It would have easily gotten to above 500+° had I had more patience. Just an FYI if anyone is having trouble getting a high temp on full. Close the probe port! It makes a huge difference! The outside temperature during the cook was 42°.
