Just bought the Taylor 1470 and used it in a piece of sausage just to try it out. I set the temp at 170 (on the gage) and left it smoke. after about an hour the thermo temp read HI.today I got a cup of water that I mocrowaved for 2min and put the probe in to see what happened,same thing.thermo temp reading HI. I'm thinking I have a bad unit.anyone else ever have this problem?
