I havent brewed in a while and just went out to kind of check on things in the brew shed in prep for upcoming brews.. Opened the ferment room and it was cold as heck. the temp controller was switched to HEAT but the heater was not on. I pulled the heater and plugged it into another outlet and it worked fine. pulled the temp controllr apart and some wires were all melted inside, and the controller itself was even disfigured from heat. the cool side works fine but the heat side is trashed so I have to get a new one. I THINK I used way too small gauged wire and melted it. So a little tip for future builders, use the heaviest wire you can fit in the controller. Now I gotta buy a new one.
