Lg Ice Maker Not Working But Water Does

Introduction

It’s frustrating when your LG refrigerator dispenses water just fine, but the ice maker refuses to produce any ice. This is a common issue homeowners face, especially during warmer months when ice is in high demand. The good news is, this problem doesn’t always require a costly repair or a new refrigerator. Often, it’s a minor issue you can resolve yourself. Addressing this quickly prevents food spoilage due to fluctuating temperatures caused by frequent door openings while searching for ice.

Common Causes of LG Ice Maker Not Working But Water Does

Several factors can cause your ice maker to stop producing ice while still dispensing water:

Frozen Water Line: A frozen water line restricts water flow to the ice maker.
Ice Buildup: Excessive ice buildup in the ice maker can prevent it from functioning correctly.
Faulty Ice Maker Module: The ice maker module could be malfunctioning and unable to initiate the ice-making process.
Low Freezer Temperature: If the freezer temperature is too high, the ice maker won’t freeze water.
Clogged Water Filter: A clogged water filter restricts water flow to both the dispenser and the ice maker, but sometimes affects the ice maker first.
Defective Water Inlet Valve: The water inlet valve controls the water flow to the ice maker. If it’s faulty, it may not open properly.
Ice Maker Arm Position: The ice maker’s shut-off arm might be in the “off” or raised position, preventing ice production.
Power Outage/Surge: A recent power outage or surge could have temporarily disrupted the ice maker’s operation.
Door Switch Issue: A faulty door switch may not signal the ice maker to start.

Symptoms Checklist

Use this checklist to help pinpoint the issue:

Water dispenses normally.
No ice is being produced.
You might hear the water dispenser working, but no sound from the ice maker.
The ice maker arm is in the “on” position.
Freezer temperature is set correctly (typically around 0-5F or -18 to -15C).
Ice maker shows visible signs of ice blockage.

How to Fix LG Ice Maker Not Working But Water Does Step-by-Step Guide

Follow these steps to troubleshoot your ice maker:

Check the Freezer Temperature: Ensure the freezer is set to the recommended temperature (0-5F or -18 to -15C). Adjust if necessary and wait a few hours.
Inspect the Ice Maker Arm: Make sure the ice maker’s shut-off arm is in the “down” or “on” position. Sometimes it accidentally gets bumped into the “off” position.
Listen for Ice Maker Sounds: Listen closely to the ice maker. Is it making any sounds at all? If not, proceed to the next steps. If you hear humming or clicking, it might indicate a motor issue.
Check for Ice Blockage: Look inside the ice maker for any large ice chunks that may be blocking the mechanism. Remove any visible ice.
Check the Water Filter: The water filter could be clogged, restricting water flow. Locate the water filter (usually in the upper right corner of the refrigerator compartment or in the base grille). Replace it with a new one according to the manufacturer’s instructions.
Thaw a Frozen Water Line: A frozen water line is a common culprit. Unplug the refrigerator. Locate the water line behind the refrigerator. You can try thawing it with a hairdryer on a low setting (be careful not to overheat the plastic). Alternatively, leave the refrigerator unplugged for a few hours to allow the line to thaw.
Reset the Ice Maker: Some LG refrigerators have a reset button on the ice maker. Consult your owner’s manual to find its location (often on the side or underneath the ice maker). Press and hold the reset button for 3-5 seconds.
Check the Water Inlet Valve: This valve controls water flow to the ice maker. It’s located behind the refrigerator, near where the water line connects. Visual inspect it.
Power Cycle the Refrigerator: Unplug the refrigerator for 5-10 minutes. This can sometimes reset the system and resolve minor glitches.
Inspect Door Switch: Make sure the door switch is working properly. With the door open, press the switch manually. You should hear the refrigerator light turn off and on. If the switch is faulty, it may not signal the ice maker to start.
Check for Kinked Water Line: Carefully inspect the water line running to the refrigerator. Kinks can significantly restrict water flow. Straighten any kinks you find.

Fix the Issue Without Buying Parts

Often, you can resolve the ice maker issue without replacing parts:

Regular Cleaning: Regularly clean the ice maker area to prevent ice buildup.
Filter Maintenance: Replace the water filter every 6 months, even if it doesn’t seem clogged.
Temperature Monitoring: Ensure the freezer temperature is consistently within the recommended range.
Visual Inspection: Regularly inspect the ice maker and water line for any signs of damage or blockage.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the ice maker still isn’t working, a replacement part might be necessary. The most common parts to fail are the ice maker module ($50 – $150 USD), the water inlet valve ($30 – $80 USD), or the water filter housing ($20 – $50 USD). Consider consulting a qualified appliance repair technician to diagnose the problem accurately before replacing any parts.

Safety Warning

Always unplug the refrigerator before performing any maintenance or repairs.
Avoid working with water near electrical components to prevent electric shock.
Be careful when using a hairdryer to thaw a frozen water line. Avoid overheating the plastic.
Do not use excessive force when removing ice from the ice maker.

Tools You May Need

Screwdriver (Phillips and flathead)
Pliers
Towel or sponge
Hairdryer (optional, for thawing)
New water filter
