The main problem as I can see is your thermostat. Usually home fridges have a junk thermostats with on/of difference as much as 10 F.

So, when you set up your temperature make sure the ON temperature is still in safe range.

Also there is a defrost relay which starts 4-6 times a day. YES EVERY 4-6 HOURS. This brings your temperature even higher....

For this reasons fridges set up lower then you even need to keep your food safe.

If you want to make it work like Swiss watch you have to replace junk thermostat with good one and play with defrost timer.

This will pay off in couple years....
