Jungapo1 for Model Number RS267LASH/XAA My refrigerator has defective defrost heater in the fridge side. It is opened when measured with an ohmmeter. I am thinking of replacing the main board too because it could be the reason why the defrost heater became defective. The defrost heater may not be designed to be energized continuously and this could happen if the main board is defective. That is the reason why other refrigerators will fail again if the defrost heater or evap assembly is the only one being replaced. Other part to replace is the defrost sensor. If this sensor is defective it could send wrong signal to the main board and in turn it energizes the defrost heater longer than it should be. I just want to know if someone could confirm my assessment as mentioned here. Thanks.
Answer Hi. All you said is absolutely true. It is a known fact that any electrical device can cause an issue. It is unfortunate but it is known that type of failure can occur when the unit is in defrost cycle and a power surge occurs wiping out all in its path. You can use a appliance surge protector for a better cheaper insurance and they work well enough. The main board is part # DA41-00104M. The evaporator assy part # DA96-00020Q has all the parts you need otherwise and is the only way to get the heater as well. Please call A.P.P. Customer Service @ 1-877-477-7278. Thank You.
