Hi, Unplug the refrigerator. The automatic defrost is not working properly. You will need to remove the rear panel inside the freezer section and test the defrost heater and bi-metal switch. The bi-metal switch located on the top of the evaporator coil needs to be tested while it is still cold. Check and see if the switch has continuity. If the bi-metal switch shows an open circuit, replace it. If it shows a closed circuit, test the defrost heater the same way. If both the defrost heater and the bi-metal switch are ok, the defrost timer will need changed.
You will need to defrost the evaporator coils with a hair dryer. Please let me know if this helps you at all or if I can assist you further.
Thanks
Vic
