Customer Questions and Answers for Replacement Icemaker by Whirlpool

Hi Judy. WATER VALVE / ICE MAKER TEST : If the ice maker is dispensing ice once filled in the bin, then it is getting power to the head of it. Remove the front cap of the ice maker (white cover pops off). At the L and N insert your meter leads to see if the 120 vac is present like suspected. If so then you can pull the unit out and identify the water valve at the machine lower rt. side from the back. Look for the solenoid which the ice maker fill line connects to. Shut off power and unbolt the water valve assy. w/ hoses attached. Noe then you have access to the solenoid connections. Unhook the wires and ohm the solenoid. It should have substantial resistance noted and then each terminal leg should not be shorted to ground. If so then the water valve is part # W10408179. Test from each terminal to the metal body bracket. Then reinstall the wires on the water valve. Insert the meter leads in the back of the wire connectors for a positive connection on each lead. Place your meter in the 300vac scale and face it forward so you can see it from the front of the unit. Then use a solid piece of 14gauge wire approx 4" long. Strip both ends back approx 3/8" and place one end in the T and H terminals and see if the large facing ice maker gear (blk or red) pointer usually at 5:00 will turn to the 7"00 position and then remove the jumper wire. The ice maker should move now on its own. If it has no reaction then the ice maker part # 4317943 is bad. When the dial and outer pointer reaches approx 3-4:00 it will send the 120 vac to the water valve as you only now have approx. 6-seconds to verify the voltage on the face of the meter. If the ice maker is good then you should hear the water valve groan and try to send water. There you have it all. You can remove the jumper and if the ice maker pointer is at rest at 4:00, then you can re-test for the voltage if you missed it b/4. Thank You.
