Late yesterday I noticed my beer lines and kegs were beginning to freeze.
I assumed I had let my probe rest in a poor place and the Ranco made it run too long. I set it to a higher temperature, moved the probe to a new location, put in some warm water in 2 liter jugs etc.
Well, Today I cleaned everything up and put my probe in a 2" pvc pipe with holes drilled in it so that it couldn't rest against a newly added warm keg or up against the cold freezer wall.
Cool so far. Next, I fought my Ranco controller that kept giving me an "E2" error code. That code means the programming is not set. Well I played with it for over and hour unplugging etc. It wasn't giving me the error last night and did not start until today when I unplugged it to reroute cables. Searching the internet, It seems this is not a repairable problem. I found this thread among others.
1. Well it is working at the moment.. Should I replace it or at least have a standby for next time?
2. What do you think about the pvc pipe method to protect the probe? I see others insert it in water or such but it seems that would make the controller too slow to respond to temperature changes.
