DetailsWant to brew lagers year round? Then the Refrigerator Thermostat Control, manufactured by Johnson Controls, is for you. Hook one of these up to that extra refrigerator and you're all set. This unit has a metal probe that you place inside the refrigerator or freezer. The probe reads the inside temperature, and adjusts to within 3.5 degrees of the temperature you set on the analog dial. This unit can be set between 20 and 80° F in one degree increments. Many brewers have found old refrigerators in the paper for 20 bucks, or even free. Add this unit and you'll be lagering in no time.

4.8 / 5.035 ReviewsA great way to brew beer and ferment wine in TEXAS!!I have been using this thermostat with my 15 cubic foot chest type deep freeze to brew beer and to ferment wine for about 3 months. It holds the temp within about + or - 3 degrees F of the set temperature on the thermostat dial. The thermostat turns the power completely off to the freezer when the temp inside the freezer reaches about 3 degrees below the set temp. As the temp rises to about 3 degrees above the set temp it turns the power back on to the freezer. The manufacturer designed it that way so the compressor on the fridge or freezer does not have to start so frequently and cause premature failure of the compressor. I have a digital thermometer with a probe that is inside the freezer, and the digital readout on the outside of the freezer. This shows me at a glance that the thermostat is working properly. A great tool for the home brewer or winemaker. (Especially if you live in the warm climate like TEXAS.)September 21, 2010Essential equipment for a keezer setupI use this thermometer control for a keg freezer and it works great. Set at 40 degrees it runs down to 36 degrees then shuts the freezer off until it hits 40 again. Easy on the compressor and an easy way to turn a chest freezer into a keezer.December 3, 2010greatVery good product easy to put on, and works great. one of the best things I have purchased in a long time!!!!March 8, 2012Good ControllerThis is a great solution if you don't need the ability to heat and cool. I have it connected to a chest freezer. I monitored the temperature of my fermenter and the temperature inside the freezer with a thermometer in a bottle of water. After lots of observation and monitoring, here is the bottom line: The temperature of a bottle of water stays almost exactly at the temperature set on the controller. It is very accurate. The fermenter runs a little warmer during the first 2-3 days, due to high activity. It ran about 5 degrees above the temperature inside the freezer. Then it settled down to the same temperature as the freezer. This controller works great if all you need to do is cool. I live in a warm climate, so it works great for me. I highly recommend this. It isn't digital, but it is very accurate and works great.February 10, 2015Worked as advertisedSo far so good. I opened it up and dropped it right out the box lol and it still works perfect. I used it for the first time on a java stout and it held the temp in my full sized refrigerator within 2 degreesNovember 24, 2016Purchased

1 year agoWell Worth ItThe thing will hold a fridge within a degree of where you want it to. It is easy to install. (despite no real directions) If you want to dink around with temp and get your goods just right, it can't do you wrong.June 25, 2010Built to last!I have had this exact model for over ten years. It still works great! I totally agree with an earlier reveiwer that a larger temperature swing will make your freezer last longer. I have the same small chest freezer and it still works great too. I moniter the temperature of the fermentation and while the thermostat will allow the air temp to swing by ~4?�� the liquid beer is usually within a degree or two. I think this control costs less now then when I purchased.January 9, 2011

Browse 2 questions Browse 2 questions and 11 answersWould this work on a mini fridge?BEST ANSWER: Yes, just plug the refrigerator into the controller, put the probe inside the fridge, then set your desired temperature. Note: your temperature range will be anywhere from the temperature the fridge maintains without the controller, up to room temperature. With a freezer you can go colder, but the fridge is limited on the cold side by it's own thermostat.Will this work on a freezer?BEST ANSWER: Hi John,
Yes, it will. A refrigerator's condenser will typically last longer though, since it is designed to start and stop more frequently than a freezer's. At least that's what I've heard from others, so I could be wrong about that.
