Short answer
Check five things first: the shut-off arm or switch, a freezer warmer than about 0 °F, an overdue water filter, a closed or kinked supply line, and ice jammed in the bin or ejector. If all five are fine, the inlet valve, a frozen fill tube, or the ice maker module itself is the likely cause.
The five checks
- Shut-off arm down / switch on
- Freezer at about 0 °F
- Filter replaced on schedule
- Supply valve open, line not kinked
- No ice clump jamming the bin or ejector

What the result tells you
| You see | Possible cause |
|---|---|
| No water reaches the mold | Inlet valve, frozen fill tube, supply issue |
| Water in the mold, never ejects | Freezer too warm or ice maker module |
| Small or hollow cubes | Low water flow: filter, pressure, valve |
| Ice in the freezer floor | Overfilling or a leaking fill tube |
Don't attempt
Leave this to a professional
- Using a heat gun or sharp tools on a frozen fill tube
- Inlet valve replacement
Stop and close the water valve if
Safety
- Water is pooling under the refrigerator
- Ice is forming on the freezer floor or behind the ice bucket
- The supply line is cracked or dripping
How it's diagnosed
A technician usually runs a test cycle to see whether the ice maker rotates and calls for water, then checks whether the inlet valve opens and how much water reaches the mold. A frozen fill tube is thawed and the cause — often a freezer running too cold or a slow-dripping valve — is addressed so it doesn't refreeze.
Cost and repair-or-replace
Inlet valves and ice maker modules are both replaceable parts; neither is normally a reason to replace the refrigerator. If the refrigerator is old and the ice maker is the only fault, some owners simply turn the ice maker off and use trays.
What to request
A symptom points to likely causes; only testing confirms one. If the checks above don't solve it, request a diagnosis for ice maker repair and mention what you've already checked.
Common questions
How long does a new ice maker take to make ice?
Often a day or more after installation or reset. Check your manual for the expected time.
