We ordered a new MES 130 in October and have used it two or three times. Today, when I am programming in the temperature and time, as soon as I press up arrow, the hours go to 1:01 and the unit starts. After a few tries it reluctantly went to 3 hours. I've turned it off and back on and now while heat starts, I cannot do any programming. WARRANTY claim. So much for smoking a ham for New Years. I've had units previously and they survived being out in the cold. It is covered so no rain/sleet/snow can get in the unit.
