J Kang for Model Number MFF2558VEB I have a Maytag french door unit. I have had an issue with the vents in the back of the lower door freezer section frosting up, especially on the sides. When this occurs, the fridge vent does not receive air and is not cold. When I run the forced defrost with the freezer door shut, it does not melt the frost. However, when I run the forced defrost with the freezer door slightly open, I can see the head hitting the coils and hear the sound of ice melting, as well as visibly see it melting. After the cycle and shutting the door, the vents frost again within 24 hours. Based on this situation, is it safe to assume that the control board is faulty because the heater seems to be working correctly?
Answer Hello J kang. I would look for a leaking door gasket letting the coils frost over. It sounds like the defrost system is working based on the test you did. May have an issue with the door not sealing. If it is not the door gasket, then you will need to replace the control board on the unit. Read More...
