• Verify control panel settings
• Kids sometimes turn it off accidentally

2. Is the Water Supply Connected?

Check:

• Water supply valve behind refrigerator (should be fully open)
• Water line not kinked or frozen
• Home water supply working properly

3. Is the Freezer Cold Enough?

Temperature Requirements:

• Freezer must be 0-5°F
• Ice maker won't work if too warm
• Check freezer thermometer
• Adjust temperature if needed

Wait Time: Allow 24 hours after temperature adjustment

Common Ice Maker Problems

• Professional repair may be needed

Problem 3: Small or Hollow Ice Cubes

Causes:

• Low water pressure
• Clogged water filter
• Partially frozen water line
• Faulty water inlet valve

Solutions:

• Check home water pressure (should be 20-120 psi)
• Replace water filter
• Thaw any frozen sections
• Increase water flow to ice maker

Problem 4: Ice Tastes Bad or Smells

Causes:

• Old water filter
• Stale ice (not used frequently)
• Absorbed freezer odors
• Dirty water supply

Solutions:

• Replace water filter immediately

• Replace damaged components
• Adjust water fill level (if adjustable)

Problem 6: Ice Maker Cycles But No Ice

Likely Causes:

• Water inlet valve failure
• Frozen water line
• Clogged water filter
• Low water pressure

Diagnostic Steps:

1. Listen for water filling sound
2. If no sound, check water supply
3. If sound but no water, valve likely faulty
4. If water enters but freezes immediately, temperature issue

Step-by-Step Troubleshooting

Step 1: Visual Inspection

Check For:

• Ice buildup blocking mechanism
• Proper ice maker position
• Water in ice tray
• Frozen water line
• Loose connections

Step 2: Test Water Supply

Process:

1. Turn off ice maker
2. Locate water line

4. Place in container
5. Turn on water supply
6. Should have steady stream

If No Water:

• Check supply valve
• Inspect for kinks
• Test water inlet valve
• Check home water pressure

Step 3: Check Water Filter

When to Replace:

• Every 6 months (minimum)
• More often with heavy use
• If water flow is slow
• If ice tastes bad

How to Replace:

• Locate filter (usually inside fridge or in base grille)
• Turn counterclockwise to remove
• Install new filter
• Run water dispenser 5 minutes to flush

Step 4: Test Ice Maker Cycle

Manual Test:

• Locate test button (usually on ice maker)
• Press and hold for 3 seconds
• Ice maker should cycle
• Listen for motor and water sounds

What Should Happen:

• Motor turns
• Water fills (if supply working)
• Arm moves
• Ice ejects (if any present)

Step 5: Check Freezer Temperature

Proper Settings:

• Freezer: 0-5°F
• Refrigerator: 37-40°F

If Too Warm:

• Adjust thermostat
• Check door seals
• Ensure proper airflow
• Don't overfill
