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 Test the Water Inlet Valve:
- Locate the Water Inlet Valve:
- The water inlet valve is located at the lower rear of the refrigerator or freezer.
- Locate the water supply line coming into the valve.
- Turn Off the Water Supply:
- Turn off the water supply at the source (typically under the sink).
- Disconnect the Water Supply Line:
- Disconnect the supply line from the valve and place it into a container to catch any water that may spill out.
- Remove the Inlet Valve:
- Remove the screws securing the inlet valve in place.
- Label and Disconnect the Wires:
- The water inlet valve is connected by two or four wires.
- Label the wire placement on the water inlet valve before disconnecting the wires.
- The wires are connected to the terminals with slip-on connectors. Firmly pull the connectors off of the terminals (do not pull on the wire). You may need to use a pair of needle-nose pliers to remove the connectors.
- Inspect the connectors and the terminals for corrosion. If the connectors are corroded, they should be replaced.
- Test the Valve with a Multimeter:
- Use a multitester set to the ohms setting X1.
- Place a probe on each terminal of the valve. The multitester should display a specific resistance value, which varies depending on the model of the valve. Consult your appliance’s manual for the exact resistance specification.
- A normal reading will typically range between 500 to 1500 ohms. If the reading is outside this range or if it shows zero or infinity, the valve is likely faulty and needs to be replaced.
- Inspect for Mechanical Blockages:
- Visually inspect the valve for any blockages or debris that might be preventing it from functioning properly. Clear any blockages if found.
- Reassemble:
- If the valve is functioning properly, reassemble by reconnecting the wires, securing the valve in place with screws, and reconnecting the water supply line.
- Turn on the water supply and check for leaks.
- Plug the refrigerator back in and test the ice maker or water dispenser to ensure proper operation.
By following these steps, you can accurately test the water inlet valve to determine if it is functioning correctly or needs to be replaced.
