So I've been using the controller without a hitch for about 3 weeks now. And this morning I came down to my lagerator and found the controller off but the fridge running (it's hardwired into the fridge's power).
Checked the connections, one or two looked like they kind of came loose, readjusted with power off, plugged in the fridge and the controller didn't turn on like it normally did. I hit the power button it came on, but was cycling like crazy with the clicking that usually comes with turning on a heating or cooling element.
I'm wondering if something else came loose in my wiring. Didnt have time to fiddle with it so I'll have to go through everything later. I ordered another one just in case something went bad in mine.
