i recently picked up a Maverick remote thermometer. I have used it 3 times once on BBB, once on fatties and just yesterday on some sausage. It has been flawless until today. I am smoking a whole chicken and the "food" temp is reading anywhere from 135-150 and the bird is fresh out of the fridge. I removed the probe from the meat and stuck it in the snow, it still reads in the 120's. I changed the batteries and it did not change. Any ideas??
