Pull the freezer panel and check frost pattern. Thaw out if completely frozen.
If you have a meter, check the defrost heater and thermostat, should be around 30 ohms with the thermostat at freezing temperature.If bad order AP4069790. If ok, replace adaptive defrost board behind the control panel AP4070403
