Hi all - I've used my ET-732 a couple times with no problems. When I plugged in the BBQ (probe 2) sensor this morning, it registered 145F. I plugged/unplugged it several times to make sure it was seated all the way in and got the same thing. I plugged the BBQ probe into the food (probe 1) side, and it came up the same. If I left it in a few minutes, it would fluctuate between roughly 145 and 150. I cycled the power on and off, toggled F and C, and reseated the batteries as well. Same thing.
I then plugged the food probe in and it registered the correct room temp. I took the unit outside and again the food probe read the correct temp (57F), and the BBQ probe was still way high. I switched the sides and it did the same thing, food probe correct, BBQ probe not.
I fired up my WSM and put both probes inside. As the temp climbed, the food probe shot up, and the BBQ probe climbed as well, but more slowly. Eventually they both settled in around 250. I left them in for about an hour and then removed them, and the BBQ probe then exactly matched the food probe returning to the ambient air temp. It seems to be OK now, I'm using it for a pork loin "as we speak".
Has anyone else experienced this phenomenon with this unit or have any idea what caused it? Do I have a bum unit?
Thanks in advance!
