I just received a pre-wired Johnson Controls A419 Digital Temp Controller from Northern Brewers.

http://www.northernbrewer.com/temp-control.html

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...

mike

fyi

Just to close on this. I got in touch with NorthernBrewers.com and they said it sounded like a defective unit.

They are sending me a new one.

I ordered a Johnson A419 but it was not pre-wired. Can anyone provide instructions on how to wire this to a GE chest freezer? I did some searching but was unable to find anything.

Thanks for the help.

How to wire a Fridge Controller 101

Keep in mind that you're not hard wiring the freezer to the thermostat. This describes taking an extension cord, cutting it in half, using the male end to the power source, and you plug your freezer into the female end.

The A419 wiring link posted in this forum is no longer active. The following link will work (at least until it's deleted).

Sorry to ressurect an old thread, but the link posted by p-nut no longer links to the instructions. I was wondering if anyone knew of any other source for getting the wiring diagrams. Every search I run turns up a link to the dead site...

Thanks,

Dead thread resurrection- I have an old fridge that I am using as fermentation chamber, and want to install a temp controller. I have heard many people say I should hard wire the thermostat, and this post says you can just plug the fridge into the unit and then the wall. What are the cons of this simple solution?

Take a 3 prong extention cord and cut it in half. The power cord coming from your fridge plugs into the extention cord, then goes to the controller, then goes into the wall.

This way you aren't modifying the fridge. Make sense?
