This is the newer type side by side with the steel heater element at the base of the fridge evaporator and the two black round thermal fuses.
The defrost heater is working as the evaporator is clear but it seems to be building up frost at the top right of evaporator where the copper tubing comes into the cabinet. This then builds up and starts icing up the fan.
Is this another known design fault issue again (although it’s been fine for 3 years) and is there a fix for it?
