Ice Maker Not Making Ice? Causes and Fixes by Symptom

Ice maker not making ice is usually a simple supply or temperature problem: the freezer is too warm, the ice bin arm or switch is off, the water line or filter is blocked or frozen, or the water inlet valve has failed. Check those in order.

Most take under half an hour, and you do not need to pull the fridge apart for the first checks.

Ice maker not making ice: the quick answer

An ice maker needs three things: a freezer cold enough to freeze the water (about 0 degrees Fahrenheit), a water supply that reaches the fill tube, and a working mechanism to cycle the mould and release the cubes. Missing any one stops production. Work through the checks from the freezer settings to the water line.

Quick facts: ice maker not making ice
Time needed	15 to 60 minutes
Tools	Thermometer, screwdriver, hairdryer, towels
Difficulty	Easy to moderate
Safety	Unplug the fridge before touching internal parts or the valve

Checks, from easiest to hardest

1. Is the ice maker turned on? Lift the wire arm, or check the switch or control. A raised arm means off on many models.
2. Is the bin seated and not jammed? A full or misaligned bin can stop the cycle. Clear any ice jam.
3. Freezer temperature. It should be around 0 degrees Fahrenheit. Warmer air produces slow, small or hollow cubes.
4. Water supply valve. Make sure the shut-off valve to the fridge is fully open and the line is not kinked.
5. Water filter. A clogged filter restricts flow. Replace it if it is overdue.
6. Frozen fill tube. A thick ice plug in the fill tube blocks water. Thaw it gently with a hair dryer, never with sharp tools.
7. Inlet valve. If water does not reach the mould, the electric inlet valve behind the fridge may have failed.

What each symptom suggests

Symptom	Likely cause	Fix
No ice at all, arm raised	Ice maker switched off	Lower the arm or switch on
Small, hollow or irregular cubes	Low water flow, clogged filter, frozen fill tube	Replace filter, thaw the tube
Ice clumped together	Freezer temperature swings, old ice	Empty the bin, check temperature
Ice maker cycles but no water	Failed inlet valve or kinked line	Test or replace the valve
Mould full of water, not freezing	Freezer too warm, thermostat issue	Lower the setting, check the fridge
Ice tastes bad	Old ice, filter, strong odours	Replace ice and filter, clean the bin

Why the fill tube freezes

Water drips from the fill tube into the mould. If the freezer is warm or the door is often left open, the drips partly melt and refreeze into a plug. Fix the temperature and the door seal, and the plug should not return. A door that does not seal is also the usual reason for frost in the freezer.

Resetting the ice maker

Many ice makers have a reset: hold a small test button or switch the unit off and on, as the manual says. The mould heats, empties, and starts a fresh cycle. Allow several hours for the first full bin, and discard the first batch after a long idle period.

Water filters and ice

Replace the water filter on schedule. A clogged filter lets only a trickle through, making small cubes. If you changed the filter recently and ice stopped, the filter may be seated badly or need the air purged: run several litres through it as the manual describes.

When to call a professional

Call if the inlet valve is faulty, the freezer will not hold temperature, the ice maker module has failed, or water leaks. These repairs need parts and testing. If the ice maker not making ice problem comes with a warm fridge, the sealed system may also be at fault.

Ice maker not making ice: the water side

Many ice maker faults start with the water supply. Check that the valve behind the fridge is open and the line is not kinked. A slow fill or a fill tube that has frozen will produce few or misshapen cubes. Let the freezer warm for a few hours to clear ice from the tube, then reset the ice maker. Water filters that are clogged or past their change date also reduce output, so replace them on schedule. If the ice maker still does not make ice after the water side checks out, the arm, the sensor or the control board may need replacing.

A reset clears many faults, but an ice maker not making ice after a reset needs a closer look. If your ice maker not making ice problem started after a water filter change, check the filter first.

If the ice maker not making ice problem repeats each winter, check the freezer temperature and the fill tube.
