Previous question states that this part (WR57X10007) is for the filter and dual solenoid valve WR57X10006 is for water/ice. I have no ice or water, so which part should I change out? Not sure what this part does for the filter.
If the unit is not making ice then and you do not have a filter then the single water valve [AP57x10007] is what your unit will take. You will want to make sure that the water valve is getting power when the icemaker calls for water. If not then the icemaker may be at fault.
