What does LG Refrigerator Not Making Ice - Causes & Fix mean?

Usually the ice maker is switched off or the freezer isn't cold enough. Turn it on, check freezer temp is below 0°F, and test the maker.

How do I fix LG Refrigerator Not Making Ice - Causes & Fix?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for LG Refrigerator Not Making Ice - Causes & Fix?

The most frequently replaced parts for LG Refrigerator Not Making Ice - Causes & Fix are listed in the Parts Reference section of this guide with OEM part numbers and typical price ranges. Check the table for direct replacements.

Is LG Refrigerator Not Making Ice - Causes & Fix a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

LG Refrigerator Not Making Ice - Causes & Fix

LG Refrigerator Not Making Ice — What’s Happening

When your LG refrigerator stops making ice, it means the ice system isn’t completing one of the required conditions: correct water supply, ice maker enabled, freezer cold enough, or a functioning fill and harvest sequence. LG’s own support flow specifically asks whether the unit has been installed long enough, whether there is ice in the bin, whether the freezer is colder than -4°F, and whether the ice maker is turned on.

This is a symptom, not a fault code. LG does not assign a single universal fault code for ice production failure. If you have an actual display code on your panel, it depends on the exact model and needs model-specific lookup.

Most Likely Causes

Ice maker turned off The ice maker toggle or control panel is set to off, or the dispenser lock is active.
Freezer not cold enough Ice makers often stop working when the freezer is above about 10°F, and LG’s support checks whether the freezer is colder than -4°F.
Low or interrupted water supply The supply valve behind the unit is closed, kinked, or frozen, or house pressure is below the required 20 psi.
Clogged or frozen fill tube or ice buildup in the bin Ice clumps or a jammed chute block the fill path or prevent the bin from seating correctly.
Dirty condenser coils or failed condenser fan The cooling system cannot maintain freezer temperature, warming the entire compartment above ice-making range.
Faulty water inlet valve The valve coil is weak or failed and cannot open to fill the ice maker, even with adequate supply pressure.
Faulty ice maker assembly The internal thermostat, motor, or harvest mechanism inside the ice maker has failed and cannot cycle.

How to Diagnose and Fix

Verify the ice maker is on at the control panel and that the dispenser lock or child lock is not active.
Confirm the freezer is actually cold enough by checking the display or placing a thermometer inside. The target is about 0 to 5°F, and LG’s support check point is colder than -4°F.
Inspect the ice bin for clumps, a jammed chute, or blocked fill path. Clear any ice buildup and make sure the bin seats correctly.
Check the water supply valve behind the refrigerator and verify the supply line is open, not kinked, and not frozen. Confirm house water pressure is at least 20 psi.
Test the ice maker using the test button. Remove the bucket and press and hold the test button for about three seconds so the ice maker begins to turn.
Reset the ice maker if needed by removing the bin, gently shaking the ice maker, reinstalling the bin, and unplugging the refrigerator for 30 seconds.
If the dispenser side also has weak flow, replace or bypass the water filter and recheck flow. A restricted filter reduces fill rate.
If pressure is adequate and the valve is powered but no fill occurs, test the water inlet valve coil with a multimeter for about 500 to 1,500 ohms and replace the valve if out of range or if it does not open during the test cycle.

Parts You Might Need

Part	Notes
Ice maker assembly	Amazon \| Replace if the freezer is cold, water supply is confirmed, and the maker will not cycle or harvest.
Water inlet valve	Amazon \| Replace if coil resistance is out of range (500 to 1,500 ohms) or valve does not open with power and adequate pressure.
Water filter or filter bypass plug	Amazon \| Replace the filter every six months or use a bypass plug if the filter is restricting flow.

When to Call a Pro

If you have verified the ice maker is on, the freezer is cold, and water is reaching the unit but production still fails, the issue may be in the sealed refrigeration system, a failed ice maker assembly, or a valve that requires multimeter testing and part replacement. Call a tech if you are not comfortable with electrical testing, if the freezer will not stay cold despite cleaning coils and checking the fan, or if the problem persists after resetting and testing the ice maker.
