LG Refrigerator Not Making Ice? Try These Fixes [2026]

Quick Fix Summary

Most LG refrigerators stop making ice because the ice maker is turned off, the freezer is set too warm, or water flow is restricted by a clogged filter or low water pressure. Start by turning Ice On, lowering the freezer to 0 F (-18 C), replacing the filter, and running the ice maker Test/Reset cycle. These simple steps resolve the issue for the majority of owners.

What Causes This Problem

When an LG refrigerator is not making ice, a few common root causes account for most cases. Understanding why they happen will help you fix the problem faster.

1) Ice maker turned off or control panel locked. Many LG French door and side-by-side models have an Ice On/Off toggle on the display or a physical switch on the ice maker module. If the control panel is locked (often by holding Lock for 3 seconds), the Ice setting might be disabled and unchangeable. This prevents the ice maker from cycling entirely.

2) Freezer temperature too high for ice production. LG ice makers need consistently cold air from the freezer and ice room. If the freezer is set above 2 F or is reading warmer than 10 F because of heavy door openings, poor airflow, or a defrost issue, the ice maker will not reach the temperature needed to harvest. LG recommends keeping the freezer at 0 F (-18 C) for normal ice production.

3) Restricted water flow from a clogged filter, low pressure, or kinks. The ice maker fill depends on household water pressure and a clean path through the water filter and inlet valve. A filter past 6 months, a saddle valve partially closed, a kinked line behind the fridge, or pressure below about 20 psi can cause too-small fill cups or no fill. LG recommends 40–60 psi for best performance.

4) Iced-over ice room fan or blocked airflow. Some LG models use an ice room in the door fed by a small fan and duct from the freezer. Frost buildup in the duct, a failing ice fan, or a door gasket leak can block cold air and warm the ice maker. This can trigger error codes like 1F, IF, or Er IF for the ice fan and leads to slow or no ice.

5) Faulty components: inlet valve, ice maker heater/motor, or sensors. If water supply and temperatures are correct but the ice maker still will not cycle, the water inlet valve solenoid may have failed, the ice maker motor may be jammed, or the mold heater may not be defrosting ice for harvest. LG control boards may log codes (such as EI for ice maker motor error on some models) when these parts fail.

Step-by-Step Troubleshooting

1. Confirm the ice maker is turned on. Look for an Ice On/Off button on the display. If the display shows Lock, press and hold Lock for 3 seconds to unlock, then press Ice On/Off to turn it on so the indicator reads On. On models with a switch on the ice maker, make sure the switch is in the On position and the bail arm (if present) is down.
2. Set proper temperatures and give it time. Set the freezer to 0 F (-18 C) and the fresh food compartment to 37 F (3 C). It can take up to 24 hours to start making ice after installation, temperature changes, or filter replacement. Minimize door openings for several hours to help the ice room reach target temperature.
3. Use Ice Plus to boost production. Press the Ice Plus (or Express Freeze on some models) button to activate a 24-hour boost that increases compressor and fan activity for faster ice. Confirm the Ice Plus indicator is lit. Turn it off after 24–48 hours once production stabilizes.
4. Run the ice maker Test/Reset cycle. Remove the ice bin to access the ice maker. Most LG models have a small Test or Reset button on the underside or side of the ice maker module; press and hold for 3 seconds until the motor starts. You should hear a harvest and then a water fill; if not, note any noises or lack of response. Do not hold the button more than 5 seconds to avoid skipping cycles.
5. Check for error codes on the display. Look for codes like 1F or IF (ice room fan), Er IF, EI (ice maker motor error on some models), rF (refrigerator fan), or dH (defrost). These often indicate airflow or component failures affecting ice. Clear temporary errors by power cycling for 5 minutes; if a code returns, address the specific fault before proceeding.
6. Inspect and replace the water filter if older than 6 months. A clogged filter reduces fill volume. Common LG filters include LT1000P (ADQ74793501), LT700P (ADQ36006101), and LT800P (ADQ73613401). Replace with a certified filter, dispense 2–3 gallons of water to purge air, then wait 12–24 hours for ice production to normalize.
7. Test water dispenser flow and household water pressure. Dispense water into a measuring cup; you should get at least 8 ounces in about 5 seconds. If weak, check that the water supply valve is fully open and the line is not kinked. LG recommends at least 20 psi minimum and ideally 40–60 psi for reliable ice fills.
8. Verify the water supply line and inlet valve. Pull the refrigerator forward carefully and inspect the water line for kinks or leaks. With water on and the ice maker running a Test cycle, listen for the inlet valve click and water flow; no sound can indicate a failed valve. The dual water inlet valve assembly on many LG French door models is commonly replaced (part numbers vary by model, e.g., AJU72992603 on some units).
9. Check the ice bin and level sensor. Make sure the ice bin is seated completely and not overfilled or jammed. Some LG door ice makers use an optical level sensor; wipe the sensor windows clean and ensure nothing blocks the beam. If your model has a mechanical bail arm, confirm it moves freely and is not stuck in the up (off) position.
10. Confirm door switches and seals. The ice maker will not cycle with the door open. Press and release the door switch(es); the interior lights should turn off when depressed, indicating the switch is working. Inspect door gaskets for gaps that can warm the ice room; correct misalignment and clean seals to improve contact.
11. Defrost the ice room duct and check the ice fan. If you see frost around the ice chute or hear a rubbing noise, the ice room duct may be iced over. Unplug the refrigerator, empty the ice bin, and leave doors open for 12–24 hours to fully defrost, placing towels to catch meltwater. After defrost, run Test again; if performance improves but frost returns, the ice fan or door seal may need service. Codes like 1F/IF point to an ice fan failure.
12. Inspect the fill tube for ice blockage. Remove the ice bin and look at the water fill tube that feeds the ice mold; a small icicle or plug can block fills. Thaw the tube gently with a hair dryer on low from a safe distance, taking care not to overheat plastic. Check for slow-drip valves or low pressure that can re-freeze and re-block the tube.
13. Reset the control board and cycle power. Disconnect power at the outlet or breaker for 5 minutes to reset the control. Restore power, confirm Ice On, and run the Test cycle again. After a reset, allow a full 24 hours for consistent ice output to resume.
14. Check for stuck ice in the mold or jammed ejector. If cubes are wedged in the mold or under the ejector fingers, the motor may stall and skip cycles. Remove the bin and gently clear any packed ice with a plastic utensil; do not pry metal parts. Restart a Test cycle to confirm the ejector turns and the mold refills.
15. Evaluate advanced component failures. If the ice maker will not harvest during Test, does not fill with known-good water pressure, or constant error codes persist, the ice maker assembly or inlet valve may be faulty. On many LG models, the ice maker assembly is a replaceable module (part numbers vary by model family, e.g., AEQ-series). If airflow-related codes (1F/IF) return, the ice fan motor or duct heater (if equipped) may require replacement.

Frequently Asked Questions

How do I reset the ice maker on my LG refrigerator?

Remove the ice bin to access the ice maker. Look for a small Test or Reset button on the side or underside of the ice maker module; press and hold for about 3 seconds until you hear the motor start. After the harvest, you should hear water fill; if nothing happens, recheck Ice On, freezer temperature, and water supply, then repeat once. Do not repeatedly cycle the test more than a couple of times in a row.

Why is my LG fridge not making ice but the water works?

If the water dispenser flows well but no ice is produced, the issue is usually temperature or ice maker control. Verify the freezer is at 0 F and that the ice maker is turned on; then run the Test/Reset. A frozen fill tube, a failed ice maker motor, or a fan/airflow issue in the ice room can also stop ice while leaving the dispenser unaffected.

What does error code 1F or IF mean on my LG refrigerator?

On many LG models, 1F, IF, or Er IF indicates an ice room fan error. This fan moves cold air from the freezer to the ice maker housing in the door; if it fails or the duct is iced over, the ice maker stays too warm to produce ice. Try a full manual defrost (12–24 hours powered off) to clear ice; if the code returns, the ice fan motor or related wiring should be tested and likely replaced.

How long should it take for my LG to make ice after replacing the filter?

After installing a new water filter, purge 2–3 gallons of water from the dispenser to remove air. The ice maker may take 12–24 hours to make the first batch and up to 72 hours to reach normal daily production. Using Ice Plus during this period can help speed recovery.

What water pressure do LG ice makers need?

LG recommends at least 20 psi minimum for the ice maker to fill reliably, with 40–60 psi preferred for best performance. If you suspect low pressure, test flow at the dispenser (8 ounces in ~5 seconds is a good quick check) and verify the supply valve is fully open and the line is not kinked. A dedicated 1/4 inch line from a cold water source with a standard shutoff valve provides the most reliable pressure.

When to Call a Professional

Call a certified appliance technician if any of the following apply:

• Persistent error codes such as 1F/IF (ice fan), EI (ice maker motor error on some models), rF (fan error), or dH (defrost) return after a full defrost and reset.
• The ice maker does not respond to the Test/Reset button, does not harvest, or does not fill despite confirmed water pressure and correct temperatures.
• You hear grinding, clicking, or buzzing from the ice maker or inlet valve during tests, indicating a failing motor or solenoid.
• There is evidence of internal frost build-up behind the panels or water leaks that require disassembly and electrical testing.

Typical repair costs (parts and labor) vary by region and model:

• Water inlet valve replacement: $150–$300.
• Ice maker assembly replacement: $200–$450.
• Ice room fan motor replacement: $180–$350.
• Control board or wiring repairs: $250–$500.
