Ice Cubes Are Too Big or Small

Troubleshooting Tips

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)
