Quick answer

First, ensure the ice maker is turned on and the water line is connected. Check for a clogged water filter or low water pressure. If these don't resolve the issue, the water inlet valve may need replacing.

Step-by-step troubleshooting

Check Ice Maker Switch
Do: Locate the ice maker switch on the front or top of the unit and ensure it is in the 'On' position.
Observe: Ice maker switch is on
Means: Ice maker is enabled but may have another issue
Next: Check water supply
Check Water Supply
Do: Ensure the water supply line is connected and the shut-off valve is fully open.
Observe: Water flows freely from the supply line
Means: Water supply is active
Next: Test water pressure
Test Water Pressure
Do: Attach a pressure gauge to the water line or use a water filter housing to check pressure.
Observe: Water pressure is between 20–120 psi
Means: Pressure is within acceptable range
Next: Inspect water filter
Inspect Water Filter
Do: Check if the water filter is clogged or needs replacement.
Observe: Water filter is clean and not expired
Means: Filter is not the issue
Next: Check water inlet valve
Check Water Inlet Valve
Do: Listen for a humming sound when the ice maker cycles. If no sound, the valve may be faulty.
Observe: No sound from the water inlet valve
Means: Valve may be defective
Next: Replace water inlet valve
Replace Water Inlet Valve
Do: Turn off power and water supply. Remove the old valve and install the new one following the manufacturer's instructions.
Observe: Water flows through the new valve
Means: Valve replacement was successful
Next: Test ice maker

FAQ

How often should I replace the water filter in my LG refrigerator?

Replace the water filter every 6 months or as indicated by the filter indicator light on your refrigerator.

Can I use a generic water filter instead of an LG brand filter?

Yes, as long as it is compatible with your refrigerator model. Check the model number for compatibility.

Why is my ice maker making cubes but not dispensing them?

This could be due to a jammed ice bin or a faulty ice dispenser motor. Check for ice buildup or blockages and ensure the motor is functioning.

Is it normal for the ice maker to make noise during operation?

Some noise is normal, but loud or unusual noises may indicate a mechanical issue that needs attention.
