I've got a Johnson Controls A419 for my mini-fridge and I am using it to ferment a lager. The problem I'm having is that I've got the unit on top of the fridge, with the 4" probe dangling inside the door. I'm having a hard time checking on the lager without throwing the temps way off in the fridge by warming up the probe. I need to get the probe closer to the carboy, but I'm not sure what kind of wire I need to use on the probe. I don't want to cut it in half to discover that I can't figure out what kind of wire I need. Anyone have those technical spec's handy?
