My Samsung RS20CCMS Fridge/Freezer does not seem to be defrosting and is filling with ice in the defrost drain hole where the heater element sits.

I have tested the defrost heater element for continuity via connecter (2) in the picture and get a reading of 460 ohms - is this correct?

Assuming the element is okay then ..

I need to test the defrost thermostat which i think is (1) -- what should it read and do i have to test it at zero degrees?

... and .. I will need to test the thermal fuse which i think is (3) - again what should it read and do i test it at any particular temperature?

There is a another thermostat on the cover which sits behind a plastic red-eye testing this for continuity at room temp shows '1' on my meter (not sure this is relevant).. This connects to the empty connector in the top right of the first pic.

Hope these images clarify.
