If you’re seeing the back wall inside your freezer coated with fuzzy ice, then your refrigerator has a defrosting problem. Welcome to my world. First order of bidness here, Hoss, is to jump J9 to J11 on that muthahboard to see if the defrost heater will glow orange. If it does, then you know the defrost heater and defrost thermostat are working. In this case, you’ll need to replace BOTH the muthahboard and the evaporator fan motor kit.
I know, right about now you’re scratching the back of your eyeball through your right nostril and axin’ yourself, “Now why would a penny-pinching broke dick, like m’damnself, go and buy an evaporator fan motor to fix a defrost problem? I’ll bet that Samurai Cyclops, or whatever the hell his name is, is just trying to get me to buy more parts!”
Oh, you’re a clever one! Y’see, Slick, they’s a thermistor that’s wired into the evaporator fan motor and it connects back to the muthahboard. What happens is that water gets inside that thermistor and shorts it out, taking the muthahboard with it. The evaporator fan motor itself can do the same thing. So, the upshot is that if you don’t change the fan motor and thermistor kit at the same time you change the muthahboard, you stand an excellent chance of burning out a brand new, expensive muthahboard.
