Re: Samsung American Fridge Freezer RS20CCMS losing temp
The problems with the samsung lie within several badly designed components.
The cause depends on one the Ice pattern, if the Ice is around the fan, then the Modified cover is required to allow heat from the defrost heater to conduct into the cover and prevent blockages in the air channels.
If the Ice pattern is solid around the evaporator then either the Thermal Fuse is O/C or the Heater is O/C.
If the Ice pattern is solid around the drain channel then the drain heater O/C or the drain hole has become blocked.
Its recommended that all Samsung models that haven`t got the replacement NTC and ducts get them replaced at the same time.
Not always a simple Sensor fault.
