Common Problems
If your ice maker is producing cubes that are too big or too small, this guide will help you diagnose and potentially fix the issue yourself.
Quick Assessment
- Check water pressure: Low water pressure often results in small or incomplete cubes
- Inspect fill tube: A partially blocked fill tube can affect ice cube size
- Examine water filter: A clogged filter can restrict water flow
- Look at the ice mold: Mineral buildup can affect cube size
Step-by-Step Inspection
1. Water Pressure Test
- Normal pressure should be between 20-120 PSI
- Use a water pressure gauge at the supply line
- If pressure is low, check for kinked lines or partially closed shutoff valves
2. Water Filter Check
- Locate your water filter (usually near the bottom of the fridge)
- Check the replacement date - filters should be changed every 6 months
- Look for visible debris or discoloration
3. Fill Tube Inspection
- Find the fill tube at the back of the freezer
- Check for ice or mineral buildup
- Ensure it's properly aligned with the ice maker
DIY Solutions
For Cubes That Are Too Small
- Clean or replace the water filter
- Check for water line restrictions
- Increase water pressure if possible
- Clean mineral deposits from the fill tube
For Cubes That Are Too Large
- Check if the water fill time is set too high
- Inspect for stuck water inlet valve
- Verify thermostat settings
When to Call a Professional
Contact a professional repair service if:
- Water pressure issues persist after checking supply lines
- The ice maker continues producing irregular sizes after basic troubleshooting
- You notice water leaks during your inspection
- The ice maker makes unusual noises
Maintenance Tips
To prevent future issues:
- Replace water filters on schedule
- Clean the ice maker system every 6 months
- Monitor water pressure regularly
- Keep the freezer at the recommended temperature (0°F/-18°C)
⚠️ Always unplug your refrigerator before performing any internal maintenance or repairs.
