Default Johnson Controls Refrigerator Thermostat

Anyone know a chain store that sells these? Are they available at Home Depot, or Lowes? Or is it an online order thing mainly?

I just sold my fridge, and am planning to buy a chest freezer this weekend.

most HVAC companies will carry them I can pick them up at N&S Supply in Fishkill but they are priced higher so even with shipping the online is lower priced dont you have a LHBS?

both LHBS's are out of stock. I was hoping to get this thing turned on tomorrow.

Well, a LHBS 60 miles away has one. It is near my mother-in-law's (who is coming over on Sunday) so i may be able to have her pick it up for me, and have it on Sunday. Aslo asked my brewclub if anyone has one. All the HVAC and resteraunt supply companies think i am an idiot when i asked them.


homebrew club member came through with a loaner i can use while waiting for one to ship!

I just bought the Johnson Digital Temp Control form Northern Brewer online, ordered on Tuesday and received it in my doorstep Friday afternoon. Cost me $88 with shipping, set it up on my chest freezer and works like a charm.

Grainger Supply sells a bunch of different kinds of controllers (ranco, johnson) including the one you are talking about I think. They have outlets all over the place but you may have to have a business account to buy from them and they aren't necessarily cheaper.

I just bought a Ranco*ETC-111000 and it was $58 delivered. It works fine.

Only thing, you have to wire it yourself. I did it and I'm not an electrician. I searched this site and others and figured it all out.

There has been some varying discussion on this. I feel that having it in a medium that allows for slower temperature changes would be more accurate. Some of us use a vial of some sort filled with ice pack gel.

I would not recommend using water with your probe. Just regulate the air temp. Water has a much higher specific heat capacity, meaning it takes a lot to heat it up and cool it off. You'll end up running your fridge for an hour and a half just to cool it a degree or two, then you'll have a really cold ambient temperature in the fridge that will keep on cooling your beer after the fridge shuts off. It only takes a few minutes at a time to change the temp inside a fridge, and if you set your differential to 2 degrees, it won't turn on but for 6-8 minutes at a time. The air temp will fluctuate 2 degrees up and down throughout the day, but your beer will stay right around the midrange temp.

I do this in my fridge, it works great.

Can I use one of these if I have a refrigerator and freezer combo?
I only want to regulate the refrigerator part and keep the freezer at normal freezer temps for meats and such.
