Good morning, seeking to find a solution to icing within my American fridge model above. Last November 2022 I manually defrosted after ice build up. This year same thing has happened with ice accumulation around evaporator pipe and fan assembly. Tested defrost heater to 351 ohms (pic attached) vs advised recommended 375 ohms if that's correct? (Note it has a slight banana shape to it). Is a new defrost heater required? Given the evaporator cover seals could potentially also be damaged would this contribute to ice build up? Is it beneficial to also replacement thermal sensor?
Any guidance would be much appreciated. ?Thanks
