Is there any way to jump electrical connections to make sure the problem is the pump and not something else.
Answer Hello Allen. If the icemaker is not filling, yes, you can swap wires and press the dispenser to see if it fills the icemaker. Also, apply 120 volts to either solenoid, and the water should flow. If not, it is a bad valve.
I need to replace 4389178 water valve assy but the old one has three valves on it the instructions on the back say to use this part only
Answer Jim, The W10408180 is the correct fill valve number to order for the model number you supplied. The manufacturer has redesigned and upgraded the replacement part. The new part also comes with instructions to install the part on your refrigerator. You shouldn't have any issues replacing and installing the replacement part.
