Couldn't find this answer while googling so hoping someone has some insight. I know that most mini-fridges/freezers are extremely simple devices at least electrically. But do thermostats have some built in logic that keeps the compressor from running constantly outside of the temperature threshold that it normally controls? Or is this logic somewhere upstream closer to the compressor?
I currently have a wine cooler I use as a ferm chamber. I set the internal thermostat to "max cool" and run the whole thing off an ITC-308. I know wine fridges aren't the best but it will get 5gals down to ~40F which is all I need. But on that way down from ambient I notice the compressor will still cut out occasionally (~10 mins?) even when the inkbird cooling relay is open. I'm fairly sure it's not a faulty compressor either. So this tells me that for some reason they designed it to keep from running non-stop. But there's nothing on the elementary schematic I can see that would indicate this.
And that is the root of my question: if I convert this to an ITC-1000 and cut out the internal thermostat am I asking for trouble? Is there normally some logic that should keep compressors from running constantly while they are on their way to a target temp?
