The water inlet valve controls the water flow into your refrigerator. If it malfunctions, it can cause issues with water supply to the ice maker or water dispenser. Follow these steps to check the water inlet valve:
Caution:
Please read our safety information before attempting any testing or repairs.
Before testing the water inlet valve, unplug the refrigerator to avoid an electrical shock hazard.
Steps to Check the Water Inlet Valve:
- Turn Off the Water Supply:
- Locate the water supply line coming into the valve, typically found behind the refrigerator.
- Turn off the water supply at the source, usually under the sink.
- Disconnect the Supply Line:
- Disconnect the supply line from the water inlet valve.
- Place a towel or container under the connection to catch any water that may spill out.
- Remove the Water Inlet Valve:
- Remove the screws that secure the inlet valve in place.
- Carefully pull the valve away from the refrigerator.
- Label and Disconnect Wires:
- The water inlet valve is connected by two wires. Label the wire placement on the valve before disconnecting them.
- The wires are connected to the terminals with slip-on connectors. Firmly pull the connectors off the terminals (do not pull on the wire itself). You may need to use a pair of needle-nose pliers to remove the connectors.
- Inspect for Corrosion:
- Inspect the connectors and terminals for any signs of corrosion. If the connectors are corroded, they should be cleaned or replaced.
- Test the Water Inlet Valve:
- Use a multimeter to test the continuity of the water inlet valve. Set the multimeter to the ohms setting (Ω).
- Place the probes on the terminals of the valve. A functioning valve should show a reading between 500-1500 ohms. If there is no continuity or the reading is outside this range, the valve is likely defective and should be replaced.
Summary:
Checking the water inlet valve involves turning off the water supply, disconnecting the supply line, removing the valve, labeling and disconnecting the wires, and testing the valve for continuity using a multimeter. Proper safety precautions, such as unplugging the refrigerator, must be taken to avoid electrical hazards. If the valve is faulty, it should be replaced.
