At the start of my last cook the display indicated 'no probe'. If I removed and re-inserted the plug it would flash three different numbers where the probe temp should read (200, 74, 34), then it would read no probe. I was leaving for work so I lowered my cook temp and left. Nine hours later the probe was reading a temp, though slightly off according to my thermapen.
Called customer service and they sent out a new probe. As I have twice encountered this problem at the start of a cook, I took my new probe out to test it. I plugged it in and turned the unit on, and it read 67 degrees. Boiled a cup of water and took it outside, the Amerique probe and my thermapen agreed that the water was currently 196 degrees. Went to fetch an ice bath, lowered probe temp from 67 to 33. Looked good to me.
Stuck the probe in a thawing pork butt, took it outside to the already prepped unit for an overnight cook, plugged it in: 'no probe'. Set a lower temp, started the unit and went to bed. Nine hours later the probe is working and displays a reasonable temp.
I know that the cookshack folks don't monitor this forum, but it looks like I have repeated the same malfunction with two separate probes. Anyone had any similar experiences?
