Whirlpool WRS555SIHZ06 not making ice

Hi @meneedhelp99377

When you say "water valve on the wall" do you mean the refrigerator's water inlet valves associated with both the ice maker and the water dispenser?

If not then check them to see if they're operating when they should.

Here's a link showing what the ice maker and water dispenser valve module looks like, (it is a two valve module) and a video that shows how to replace it that may help.

When the water dispenser paddle is operated to get water, 120V AC is applied to the dispenser water inlet valve to operate it so that water flows through. The valve is turned off, when the paddle is released.

The same with the ice maker. When the ice maker unit calls for water to make more ice, then 120V AC is applied to the ice maker water inlet valve to operate it and water flows to the ice maker. When the sensor in the ice maker detects that the correct water level is reached, the valve is turned off.

Here's the tech sheet for the refrigerator, that will help.

Scroll down (and zoom in a lot) to find the diagnostic test procedure and perform the test for Step.19 and Step 31. These two tests allow you to check if the dispenser valve and the ice maker valve are working OK or not.

If neither test works, do you have a DMM (digital multimeter) and know how to use it safely to test for 120V AC? You may have to find out why the required operating voltage is not getting to the valves, when it should.

As always be safety aware when testing for AC voltage!
