The evaporator coils on this unit were so frozen up they busted the fan and fan housing. I have everything defrosted off, checked the heater but not sure what the resistance should be. Do you guys have lots of trouble with the boards on these, or is this more than likely the defrost sensor?

Set your multi tester to the R X 1 scale. Place the tester’s leads on one terminal each. This should produce a reading anywhere in between zero and infinity. If your multi tester produces a reading of zero, or a reading of infinity, then your defrost heater should most definitely be replaced. There are many different kinds of elements, and so it is difficult to say what exactly the reading should be for your defrost heater. But it definitely should not be zero or infinity. If it is, replace the mechanism. As far as the control board on this exact model, we have replaced six of them this year alone. With that being said we service over 16k service customers per year and about 800 LG refrigerators. Hope this helps Matt Ace Appliance
