Common LG Ice Maker Issues
LG refrigerators use several ice maker designs including standard, slim SpacePlus, and the popular Craft Ice maker that produces large round ice spheres. Each has its own quirks. Craft Ice makers are slower by design — they produce about 3 spheres per day. If your LG fridge isn't cooling properly either, start with our LG fridge not cooling guide first.
Fix 1: Run the Test Cycle
Press and hold the Test/Fill button on the ice maker for 3 seconds. The ice maker will cycle through its test — you should hear the motor and water filling. If nothing happens, check that the ice maker is switched on (the arm or switch is in the ON position).
Fix 2: Check the Water Filter and Supply
LG refrigerators are sensitive to water filter condition. A clogged filter significantly reduces water flow to the ice maker. Replace the filter if it's older than 6 months. Also check the water line at the back of the fridge for kinks. LG recommends water pressure of at least 20 PSI.
Fix 3: Defrost the Ice Maker Area
Ice buildup around the ice maker fan or fill tube is a frequent problem. Remove the ice bin and look for frost buildup. If present, unplug the fridge and use a hair dryer to thaw the area. Some LG models have a dedicated ice maker defrost option — check your control panel. For general ice maker troubleshooting, see our complete ice maker guide.
Fix 4: Replace the Ice Maker Assembly
If the motor doesn't run during the test cycle and all other checks pass, the ice maker module has failed. LG ice maker assemblies run $100–$200. Replacement involves removing 2–4 screws and disconnecting a wire harness. Order the exact part number for your model.
