Directions for testing an icemaker water inlet valve.
Before you begin to test your icemaker's water inlet valve, make sure you disconnect the appliance's power supply. The easiest way to do this is to unplug the unit from the wall. Alternatively, you could trip the appropriate switch in the circuit breaker panel, or you could remove the appropriate fuse from your home's fuse box.
Consult with an appliance repair technician if you do not feel you have the skill or the ability to successfully complete this test.
- Locate your icemaker's water inlet valve, it is typically located behind a refrigerator. Gently pull your refrigerator away from the wall. You may want to place scraps of carpet, of some other soft material below the fridge to prevent damage to the floor. Turn of the water valve's water supply by closing the shut-off valve in the waterline leading to the water valve. Remove the lower access panel on the back of the refrigerator using a screwdriver or a nut driver.
- Place a container under the valve to catch any water that may spill from the water valve and its fill tube. Remove the water valve's fill tubing. Loosen the flare nut on the brass fitting that is found on the inlet side of the water valve. You can use a wrench to loosen the flare nut.
- Your water inlet valve is held in place on your refrigerator by means of a metal bracket. Use a screwdriver or a nutdriver to remove the screw that holds the water valve's bracket to the refrigerator cabinet. Gently pull the water valve out of the cabinet, and remove the tube from the outlet port.
- There are two wires connecting to the terminals of your water inlet valve. If yours is a double solenoid water valve, it will have four wires. Be sure to label each wire so that you know where to reconnect them later. Firmly grasp the metal connector of the wires in order to remove the wires. You may need to use a pair of needle-nosed pliers. Do not pull on the wires themselves.
- Set your multitester to the R X 1 ohms setting to test for continuity. Place each of the multitester's leads on a terminal. Your multitester should display a reading between 200 and 500 ohms. Closely examine your water inlet valve. The exact ohm resistance rating you should test for may be marked on the valve.
- If the test you conduct with your icemaker water inlet valve does not produce these results, then you should replace the component.
