I'm new to the forum, but I wanted to contribute my results, in case they would help anyone. I have a Haier 7.1 cf freezer (HNCM070E) that I picked up used last week, and I've been going through the process of tweaking the thermostat.
After turning the coarse adjustment screw 19 times, clockwise, the compressor shuts off around 40-41 degrees, and turns on roughly around 48-50. I've had water in it for the last 10 hours, sitting at just above 40 degrees. I hope this helps.
