I have read much info on past forums about adjusting the thermistor. All very good info for me. My question is, while I am adjusting the little wire thing it keeps slipping out of the plastic piece attached to the fin. However when I'm traveling I do not like keeping the door open too long. There fore I should do it w/o food in there. (but I forget). It seems to be cooling. But the fins get dripping while I'm working with it.
