i use a Johnson temperature controller for a ceramic heat bulb to warm my wort during the winter. i keep the bulb and wort in a freezer thats acts solely as a fermentation chamber (the freezer does not work, so all i have is a heat source in a sealed container basically.)
on my current beer, my controller has been acting up, i turn the controller on with the set point to 67 degrees. i come back after a few hours and the controller is reading 119 degrees! the heat lamp attached to the controller has cut off thankfully and the actual temp of the beer (according to a temperature strip on the carboy) is 60 degrees.
so whats happening, i think, is that the probe is broken because it reads a completely high and wrong temperature; causing the heat lamp to shut off, leaving no heat at all so the actual beer temperature is too low. anyone had this problem? do i need a new controller?
