Temp is rising in my freezer (0 to 10 in a few minutes)

definitely unplug it and plug it back in, probably fix it, at any rate that is the first thing to try.

Unplug for 24 hours and replug. After 2 hours of running, temps of fridge and freezer should be close to normal and water pan should be nearly full. If so, suspect your defrost heater as needing replacing, and note that unit will behave as-is for a few days and then your symptom will return, confirming the need for the new heater. Change the small inexpensive clip-on thermostat at the same time.

Not sure why you would want a -19 degrees when ice cream usually is about -10.
I have had some issue with their freezers not holding temp. Would have a temperature rise and cause the compressor to come on in as little as 4 minutes. Never found the cause. I would cause the compressor to come on and over heat and go out on overload. Sorry but I can not give an exacting answer. This is not normal for most freezers.

try to turn off the freezer and adjust the temp. settings to a minimum.. Make it 20 minutes for your fridge to turn off before you turn it on. If the temp. keeps on rising, refer to your freezer manufacturer to repair the thermostat inside of it.

This is normal. All commercfial freezers must defrost 3 to 5 times a day, or they will freeze over at the coil and then stop freezing. A timer in your freezer turns off the compressor and turns a heating element on for 10 to 15 minutes. During that time the coil heats and melts frost from the coil. Usually within 30 minutes the temperature will briefly rise to 20 t0 25 degrees F and then quickly drop down to 0 degrees F. The food rarely defrosts in this short period of time..

what the problem is the ports that go from freezer to frige are all iced up you just need to defrost a few hours

you do not say how full/empty you keep the freezer.
pad out empty spaces with any spare foam (stops air movement when you open door) could be faulty temp sensor...or auto defrost sensor .......rare.

try replacing the thermostat and the defrost timer
