A malfunctioning ice maker is frustrating, especially when entertaining. Before calling for service, try these troubleshooting steps.
Quick Checks
1. Is the Ice Maker On? The on/off switch can be accidentally bumped. Locate the switch and verify it's in the ON position.
2. Check the Water Supply - Verify the water line isn't kinked - Check the water shut-off valve - Test water flow from the supply line - Replace water filter if overdue
3. Clear the Ice Bin Sometimes ice clumps together, activating the sensor that stops production: - Remove all ice from the bin - Clean the bin with warm water - Dry completely before replacing
4. Check Freezer Temperature Ice makers need the freezer at 0°F or below: - Verify temperature setting - Allow 24 hours after adjustment - Check door seal integrity
When to Call a Professional
Frozen Water Line If water supply is confirmed but no ice, the fill tube may be frozen. We can safely thaw and identify the cause.
Mechanical Failure Strange noises, incomplete cycles, or ejector arm problems require professional diagnosis.
Water Inlet Valve If water doesn't fill the mold despite good supply, the inlet valve likely needs replacement.
Control Board Issues Error codes or complete non-response indicates potential control board problems.
Ice Quality Issues
Hollow or Small Cubes - Low water pressure - Partially clogged filter - Inlet valve not fully opening
Cloudy Ice - High mineral content in water - Old filter - Slow freeze process
