LG Fridge Ice Maker Troubleshooting Guide 2025, Fix No Ice, Leaks, and Bad-Tasting Cubes
Common Reasons Why Your LG Ice Maker Is Not Working
Before you start, here are the most likely causes so you know what to look for:
- Clogged water filter, restricting water flow to the ice maker
- Frozen water line, blocking water from reaching the ice tray
- Faulty water inlet valve, preventing water entry
- Misaligned ice maker arm or switch, stopping ice production
- Dirty ice bin or mold growth, creating off-tasting cubes
- Software glitches in smart fridge models that need a reset
Step 1: No Ice at All, Start with the Basics
When there is no ice, check the simple things first. Often, the issue is not a broken ice maker, but rather an easy fix.
Is the Ice Maker Turned On?
- Open the freezer and find the control arm or switch near the ice maker.
- If the arm is in the raised position, lower it to start production.
- On many LG models, press and hold the "Ice Off" button for 3 seconds to reactivate the unit.
Tip: Sometimes, kids or cleaning can switch the ice maker off without you noticing. Try this first.
Is the Water Supply Properly Connected?
- Check behind the fridge that the water line is firmly connected.
- Confirm the household water supply valve is fully open.
- Test the dispenser; if the door water does not flow, the ice maker will not fill either.
Step 2: Slow Ice Production, Replace the Water Filter
If ice comes slowly, a clogged water filter is a common cause. Filters collect minerals and particulates that reduce flow over time.
How to Replace the LG Water Filter
- Locate the filter in the fridge compartment.
- Turn the old filter counterclockwise and pull it out.
- Insert the new filter and twist clockwise until secure.
- Run 2 to 3 gallons of water through the dispenser to flush out air and debris.
LG recommends replacing the filter every 6 months. If you do not have a replacement, use the bypass plug as a temporary solution.
Step 3: Ice Tastes or Smells Bad, Clean the Ice Bin and Water Lines
Bad-tasting ice is usually the result of mold, bacteria, or old water sitting in lines. Cleaning is quick and effective.
Deep Cleaning Steps
- Empty the ice bin and wash with warm, soapy water, then dry.
- Wipe the ice maker area with a 50 percent vinegar and 50 percent water solution.
- Run several water dispenser cycles to flush the water lines.
- If the taste remains, consider an LG-approved cleaning cartridge or professional line flush.
Always discard the first few batches of ice after cleaning to ensure no residual taste remains.
Step 4: Ice Maker Leaking, Inspect Water Line and Valve
Leaks mean water is escaping somewhere along the supply path. Common causes include cracked lines, loose fittings, or a failing inlet valve.
How to Fix Ice Maker Leaks
- Inspect the water line behind the fridge for cracks or loose connections.
- Defrost if the line is frozen and causing an overflow when it thaws.
- Check the water inlet valve, usually at the back bottom of the fridge. Replace the valve if it is defective.
Step 5: Strange Noises from the Ice Maker
Clicking, buzzing, or humming often points to a jammed dispenser, frozen cubes, or motor strain.
Possible Causes and Simple Fixes
- Stuck ice cubes, gently remove using a plastic utensil only.
- Obstruction in the dispenser chute: clear any blockage.
- Turn off the ice maker for 5 minutes, then restart to relieve minor motor strain.
Step 6: Perform a Hard Reset
Smart fridges can have software glitches. A hard reset clears temporary errors and often restores normal function.
How to Reset an LG Refrigerator
- Unplug the refrigerator for 1 minute.
- Plug it back in and allow it to power up.
- Press and hold the Ice Plus button for 3 seconds, if available on your model.
When to Call a Professional
If you have followed all steps and the ice maker still fails, contact LG support or a qualified technician. Advanced issues commonly include:
- Broken ice maker motor
- Faulty control board
- Major internal water line damage
Check your warranty; most LG fridges have a 1-year warranty that may cover parts and service.
Final Thoughts and Preventive Tips
Regular maintenance is the best way to avoid trouble. Replace the water filter every six months, clean the ice bin quarterly, and run a line flush if you notice taste or flow issues. Small care steps save money and keep ice tasting fresh.

Frequently Asked Questions
How long does it take for an LG ice maker to produce the first batch after a reset?
Expect about 24 hours for the first full batch of ice. Make sure the freezer temperature is set to 0°F, or minus 18 °C.
Can a clogged water filter completely stop ice production?
Yes, a blocked filter can restrict water and halt ice production. Replacing the filter usually restores normal flow.
Why does new ice taste like chemicals?
New refrigerators often have residual manufacturing fluids. Run 2 to 3 gallons of water through the dispenser and discard the first batches of ice to remove the taste.
Do I need a technician to replace a water inlet valve?
If you are comfortable with tools and turning off the water supply, you can replace it yourself, but many prefer a technician for safety and a guaranteed repair.
Conclusion
Most LG fridge ice maker issues are solvable without a service call. Start with the simple checks, replace the filter on schedule, clean the bin, and perform a reset if needed.
