I have mine set up with a 110 heat - cool thermostat. About $12 online. The thermostat kicks on and turns a 4 watt bulb on, which in turn warms the senor for the air conditioner causing the conditioner to run. I can set up a delay as to how long it takes to turn on. This gives it time to defrost. I get a chance I'll look on youtube and get you the link to it.

That cooler is inside? The AC is not designed to go that low ! Newer models condensation points are higher for energy efficiency. Wrong type of Freon. Set it on 50 degrees. Put abag of ice in chest cavity. You won’t get 30 something with that unit without freezing up.

CROP DAMAGE tags are issued in Ky based on number of acres determined by that district biologists. 12 on my lease Didn’t say that’s all we kill. We all have 5 doe tags on our sportsman license
Local pumpkin farm has crop depredation tags. Shoot on site any deer any time
Won’t eat hot weather deer because they stink got ticks worms and more likely to be diseased

Well, it worked for the first 7 we put in it. One double in that total. Wasn't until we had a cold one, and added two more that it froze up. So, I know it works inside, down to 38*, which I'm happy with 40*. I was hoping for some insight to why all of a sudden it froze up. The only difference seemed to be humidity. I tweaked the on/off temps, and adjusted the fan timing and it's been running empty at 42* ambient. I think it's safe at 42, but would prefer 40.
I'll leave as is until we put another one or two in the cooler. If it continues, I'll order the second controller.

We haven't seen any worms or obvious disease yet in all the years we've taken warm weather deer, a few ticks, but we get them in winter too.

I'm not a reefer tech but work on them at work work quite a bit. The two biggest issues that cause freezing up are defrost times are wrong (too short or not often enough), and air leaking into the box (door seal or other holes door being left open). Not sure how the coolbot type controllers work but normal walk in systems shut the evap fans off and the flow of refrigerant off to the evaporator. often there is a heater that is turned on for most of the defrost cycle. there will be moisture in the air and sooner or later it will end up on the eval coils. defrost and good drains keep it fro m being a problem

We run Coolbot controllers and had the same problem when hanging a beef in the summer. The coolbot has 4 or 6 settings for defrost time. We just bumped the defrost time a little longer and it took care of the issue. Not sure how the inkbirds are set up but if you can extend the defrost time it will take care of the problem.

Educate me on the controllers. A $30 inkbird does the same job as a $400 coolbot? How much does it cost to run one for a week? I have an 8x8x8 box that needs a cooling unit

Square, you can set the inkbird to turn off at at a certain temp. Then set the other function to turn it back on at a different temp (+3* for me). The coolbot has a heat sensor to trick the AC into thinking its warm, the inkbird uses a separate night light to do the same thing basically. It's easy to set up, but takes some tweaking to be consistent. I had a hard time finding where to put the controller sensor, but got some help from another site. I put it directly into the AC blower, when it hits 28*, it shuts down (usually before freezing up). It stays off for a few minutes and let's the coils warm just a bit before starting again.
Using two controllers is supposed to work better, one sensor for ambient temp in cooler, one sensor for the coil fins, so when it does start to freeze at the fins, the unit shuts down. I'm just stubborn, lol. $72 for two units is still a whole lot better than $350 for a coolbot. I got the 10k AC for nothing. And jbyrd is correct that window ACs aren't made to go below 60, that's why you have to trick them into thinking it's much warmer. Lots of YouTube vids, but only a couple good ones.

Brian, Thanks for the information! It’s always good to learn from someone who has found the issues and solutions.
