how to test ice maker water valve

2. Inspect the filter screen where the supply line connects. Ice maker module test for Whirlpool icemaker: Ice maker must be plugged in to the refrigerator. Remove any debris or deposits that may have built up using a toothbrush or warm running water. Ice Maker Water Inlet Valve Check for Continuity This Valve Gets 110 volts for 7 to 10 seconds via the Ice Maker to fill the Ice Maker with water. Shut-off arm down and the freezer is cold ( below 15 F ). First, feel the hot gas valve inlet after five minutes into freeze cycle. The water inlet valve is an electrically-controlled valve that opens to supply water to the dispenser and ice maker. The water valve supplying the icemaker is a key component of the icemaking system, and it should be the first thing you check if the icemaker's performance is … Check procedures — Note: On dual expansion valve ice machines, procedures must be performed twice, once for each hot gas valve. If the ice maker is not cycling it will not call for water. When not engaged the diaphragm is closed and no water should flow. Test points T & H will verify if the bimetal thermostat is open or closed. As a result, the ice maker won’t make ice. In both cases the valve for all refrigerator ice maker systems is activated on command by the ice maker motor. Identify the correct water inlet valve solenoid for the ice maker. A solenoid is simply an electromagnet. When the ice maker is cycling as designed and the rotation of the ejector blades is unimpeded, the valve will activate on command for water supply to the ice maker and shut off automatically, as the cycle is completed as designed. In a water fill valve, the solenoid's actuator is attached to a diaphragm which opens or closes a route through which water can pass. If it appears that your ice maker is no longer producing ice, you can manually check it to determine if the ice maker has failed or if you need to check the water line and inlet valves… But keep in mind, that LG fridges have 2 inlet valves. continued from page 1. (Make sure your test probes go into the test points 1/2".) Using the unplugged 'cheater' power plug, clip a wire onto each spade terminal, or thread each stripped wire through the spade holes. As soon as the water valve's solenoid coil is powered, the armature allows the diaphragm to flex opening the passage and allowing water to … The valve requires at least 20 psi to function properly. This is the solenoid over the thinner feed line (see 3rd pic) Remove the plug-in power connector for the ice maker water inlet valve solenoid. If you cannot clear the clog, it will be necessary to replace the valve (the filter is not removable on most inlet valves). Main valve on the back of the fridge, secondary(for the ice maker) in the left door. Test points L & N will verify 120 volts to Ice Maker module. Inlet Valve – When the water inlet valve failed, you will not have water as well.In order to check the inlet valve, you just need Multimeter. If the water inlet valve is defective, or if it has insufficient pressure, it won’t allow water to flow through. You ice maker also must cycle too before it will fill the ice mold with water. Your model refrigerator uses 2 separate dual water valves which means that one solenoid on each valve must open to allow water to flow up to the ice maker.
