Quick answer

Check the water supply line for kinks or blockages and ensure the ice maker is properly connected to the water source. If the ice maker is receiving water, verify the temperature inside the freezer is below 0°F (-18°C) and the ice maker switch is in the 'On' position.

Confirm the symptom

Ice maker is not producing ice
No water flow to the ice maker
Ice maker is turned on but not dispensing ice
Freezer temperature is above 0°F (-18°C)

Tools and prep

Screwdriver
Multimeter
Flashlight
Plastic putty knife
Replacement water filter (if applicable)
Turn off power to the refrigerator at the circuit breaker
Shut off water supply to the ice maker

Step-by-step troubleshooting

Check Water Supply Line
Do: Inspect the water supply line for kinks, cracks, or blockages.
Observe: Water flow is restricted or completely blocked.
Means: A damaged or kinked water supply line is preventing water from reaching the ice maker.
Next: Replace or repair the water supply line.
Verify Water Inlet Valve
Do: Use a multimeter to test the water inlet valve for continuity.
Observe: Multimeter shows no continuity.
Means: The water inlet valve is faulty and needs to be replaced.
Next: Replace the water inlet valve.
Check Ice Maker Switch
Do: Ensure the ice maker switch is in the 'On' position.
Observe: Switch is in the 'Off' position.
Means: The ice maker is manually turned off.
Next: Turn the ice maker switch to 'On' and monitor for ice production.
Inspect Ice Maker Level
Do: Make sure the ice maker is level with the back wall of the freezer.
Observe: Ice maker is not level.
Means: An improperly positioned ice maker can prevent proper water flow and ice production.
Next: Adjust the ice maker to ensure it is level with the freezer wall.
Check Freezer Temperature
Do: Use a thermometer to verify the freezer temperature is below 0°F (-18°C).
Observe: Freezer temperature is above 0°F (-18°C).
Means: The freezer is too warm to produce ice.
Next: Adjust the temperature settings and allow the freezer to cool down.
Test Ice Maker Motor
Do: Use a multimeter to test the ice maker motor for continuity.
Observe: Multimeter shows no continuity.
Means: The ice maker motor is faulty and needs to be replaced.
Next: Replace the ice maker motor.
Inspect Ice Maker Mold
Do: Check the ice maker mold for cracks or damage.
Observe: Mold is cracked or damaged.
Means: A damaged mold can prevent proper ice formation.
Next: Replace the ice maker mold.
Check Water Filter
Do: Inspect the water filter for blockages or expiration.
Observe: Water filter is clogged or expired.
Means: A clogged or expired water filter is restricting water flow.
Next: Replace the water filter.

FAQ

How do I know if my LG refrigerator door ice maker is receiving water?

You can check for water flow by removing the front cover of the ice maker and looking for water dripping from the fill tube. If no water is present, there may be an issue with the water supply line or inlet valve.

Can a clogged water filter cause my LG refrigerator door ice maker to stop working?

Yes, a clogged or expired water filter can restrict water flow to the ice maker, causing it to stop producing ice. Replace the water filter to resolve this issue.

Why is my LG refrigerator door ice maker not turning on?

The ice maker may not be turning on if the switch is in the 'Off' position, the ice maker is not level, or there is an issue with the power supply. Check the switch, level, and power connections to resolve this issue.

How do I adjust the temperature in my LG refrigerator freezer to ensure proper ice production?

Use a thermometer to check the freezer temperature and adjust the temperature settings to ensure it is below 0°F (-18°C). Allow the freezer to cool down for several hours before checking ice production.
