LG Refrigerator Water Inlet Valve Assembly Test and Replacement

简介

Use this guide to replace the water inlet valve assembly on your LG refrigerator

This guide will work for most LG refrigerators. This guide is written with an LG model LFX25973 refrigerator. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.

The water inlet valve assembly controls the flow of water to the dispenser and also to the ice makers.

If it fails, you may experience the following:

Leaking and puddles on the floor near the refrigerator
Water freezing on the bottom of your freezer
Ice in your in-door dispenser freezing up and not dispensing
No ice produced, or no water dispensed if the valve refuses to open at all

If you have a multimeter, you can use it to test the inlet valve assembly components.
Set the multimeter to the ohm (Ω) setting.
For the first solenoid, test the resistance between the wires from it at the connector.
The acceptable resistance is 360 to 420 Ω.
Repeat the test on the connector for the other solenoid.
The acceptable resistance is 360 to 420 Ω.
To test the flow meter, test the resistance between the wires from it at the connector.
The acceptable resistance is 4 kΩ to 30 kΩ.
