Mark for Model Number ED5VHGXML13 The evaporator coils keep freezing up into solid ice and then the fan can’t blow air into the fridge side and so have to use heat gun to melt it all. I e replaced the defrost thermostat and the cool control thermostat but it’s still freezing over. Is there a defrost timer on this model or do I need to replace the ADT board? Is so what part number do I need to order? Thank you!
Answer Thank you for your question Mark. If the defrost heater WP2323198 is intact and measures a resistance between 21-27 Ohms, the defrost control board 4388932 would be the most likely cause of failure as wire harness failures are the least likely cause.
