Ok everyone I need your help! This is my first time kegging, just bought a Kenmore 7.2 chest freezer and Johnson A419 temp controller. My issue is that I've tried several ways of setting the chest freezer temp and the temp controller setup and am getting either too cold or too warm of a temp. Right now the freezer temp setting is at the factory setting (mid way), the temp controller settings are (cooling setting) SP=40 DIFF=2 ASd=1 OFS=0 SF=1 What am I doing wrong? I've also tried the heating setting on the temp controller and it warmed up too much. I'm trying to set the kegerator at 40 degrees for now.
