deep freeze to fridge conversion
So I have seen a couple well documented conversions on the internet. Nobody ever gives up which thermostat they used though. Anyone have any suggestions?

Unfortunately, I have several projects going on and the temperature controller has gotten misplaced amidst the chaos. So, until I re-discover it, my conversion project is on hold. I don't know if you have a Kill-a-Watt, but it will be super useful for you to log power use. Also, having a top-access refrigerator will call for some retraining. BTW, I have a small freezer in the cellar that has been in service for about 25 years. My Kill-a-Watt indicates that it is consuming about $25 per year. With your reduced duty cycle, your new refrigerator should run at very low cost and last you a very long time! Good luck with your project... [* I'm sure that any freezer will work very well and at minimum expense, but I did notice that in the project that Tom Chalko did, he started with the most efficient freezer he could get. http://mtbest.net/chest_fridge_1.pdf *] Best, -AC

I've done these for dedicated lab operations several times. For basically, standard operation, I use a Dayton Controls 2E206 temperature controller, you can buy them from Graingers and other places. They're around + or - 2 degrees F. For precision applications I've used the CN370 series programmable temperature controllers from Omega or a similar Red Lion control. Both about three times the price of the Dayton, not counting the addition of the thermocouple and relay needed.
