I just received a pre-wired Johnson Controls A419 Digital Temp Controller from Northern Brewers.
I plugged it in, and then plugged the fridge into it, and the fridge works fine. However, I get not information on the LCD display, and the little light on the control doesn't light up. Basically, there is no way for me to view or set the temperature.
Has anyone else run into this issue? Do I have to set something up before using it?
When I first plug it in, characters do display on the LCD, but then it goes blank.
Thanks for any input or information...
