Only used it about 3 times so far. went to use it today and after running a few mins with just the smoker probe while the cooker got running at temp i plugged in the food probe. It was reading wrong, saying raw food was over 200F. after changing the batteries in the transmitter figuring it was the problem it just died all together. Transmitter wont even power up now. Guess i'll have to call maveric tommorow. Anyone deal with thier warranty dept before?
