A refrigerator ice maker that has stopped working is one of the most common appliance complaints we hear — and also one of the most frequently self-diagnosable issues. Before scheduling a repair, there are five clear checks you can make that resolve the problem in the majority of cases. This guide walks through each one in order, from the simplest to the more complex.
This is a diagnosis guide, not a full repair manual. We will help you identify what is wrong and whether you can fix it yourself or need a technician. We do not recommend attempting to replace water inlet valves or ice maker modules without appliance repair experience.
Troubleshooting Tree — Work Through These in Order
Check the Ice Maker Arm or Power Switch
On most refrigerators, the ice maker has a wire shut-off arm that rises when the ice bin is full and shuts off ice production. If this arm was bumped up into the "off" position, the ice maker will not run. Look for the metal arm inside the freezer and press it down to the "on" position. Some models have a physical on/off switch instead — check whether it is set to ON. This single step resolves roughly 20% of "ice maker not working" calls.
Check the Freezer Temperature
The ice maker requires the freezer to be at -12°C (10°F) or colder — ideally -18°C (0°F). If the freezer is warmer than -12°C, the ice maker's thermostat will not trigger the freeze cycle. Place a thermometer in the freezer and wait 24 hours. If the temperature is too high, the issue may be with the freezer cooling system (evaporator fan, defrost heater, or compressor) rather than the ice maker itself.
Check the Water Supply Line
The ice maker needs a water supply to fill the ice tray. Pull the fridge away from the wall and check the water supply line (a thin plastic or braided stainless tube) running from the wall valve to the back of the refrigerator. Confirm: (a) the shut-off valve at the wall is fully open, (b) the supply line is not kinked or pinched against the wall, and (c) the line is connected securely at both ends. A kinked line will allow very little or no water to reach the ice maker.
Check the Water Inlet Valve
The water inlet valve is an electrically controlled valve at the back of the fridge that opens to allow water in when the ice maker calls for a fill. Two failure modes: (a) the valve screens become clogged with mineral deposits — common in hard water areas like Toronto — restricting water flow; (b) the valve solenoid fails electrically and the valve will not open at all. A clogged screen can be cleaned; a failed solenoid requires valve replacement. If you hear the ice maker cycling but no water enters the tray, the inlet valve is the likely cause.
Reset the Ice Maker Module
If the above four checks pass, reset the ice maker. Many ice maker issues are resolved by a simple reset that clears a frozen state in the control module. See the brand-specific reset instructions below. After resetting, allow 24 hours before evaluating whether the ice maker is working — it takes time to produce the first batch.
Brand-Specific Reset Procedures
Samsung
Open the freezer and look for a small Test button on the ice maker module itself (usually on the front or side). Press and hold for 3 seconds until you hear a chime. Some models require holding the ice type and child lock buttons simultaneously on the dispenser panel — check your model's manual for the exact combination.
LG
Look for a Test/Fill button on the front of the ice maker module inside the freezer. Press and hold for 3 seconds. You will hear the motor begin to cycle, which indicates the reset was successful. LG ice makers with the ice maker in the French door compartment may have a reset button behind the ice bin — remove the bin to access it.
Whirlpool / Maytag / KitchenAid
Locate the feeler arm on the side of the ice maker. Press it down three times rapidly to initiate a test cycle. Alternatively, unplug the refrigerator for 5 minutes and plug it back in — this performs a full reset on the ice maker module on most Whirlpool-platform refrigerators.
GE / GE Profile
Turn the ice maker off using the on/off switch or arm. Wait 30 seconds, then turn it back on. For GE Profile models with an Advanced Water Filtration display, also check the water filter status — an expired filter on some GE models will disable the ice maker as a safety measure.
After a reset, always wait 24 hours before concluding the ice maker is still broken. The ice maker must go through several freeze cycles to produce a full bin of ice. Checking after 2–3 hours and concluding it does not work is a very common mistake.
When to Call a Technician
If you have worked through all five steps above and the ice maker is still not producing ice, the likely causes are:
- Failed water inlet valve: If the valve receives power but does not open, replacement is needed. This is a straightforward repair for a technician.
- Failed ice maker module: The control board inside the ice maker itself may have failed. The module can usually be replaced without replacing the whole ice maker assembly.
- Frozen fill tube: The thin tube that carries water from the inlet valve to the ice maker can freeze solid, blocking all water flow. This is common in refrigerators where the freezer door is opened frequently or the door seal is weak. A technician will thaw and insulate the fill tube.
- Freezer cooling issue: If the freezer is not reaching -18°C despite a correct setting, the underlying cooling problem must be fixed before the ice maker will work.

Frequently Asked Questions
The most common sudden causes are: the ice maker arm or switch was accidentally turned off, the freezer temperature rose above -12°C (10°F), a chunk of ice jammed the ejector mechanism, or the water supply line was kinked or shut off. Work through these checks before assuming a mechanical failure.
Most ice makers have a reset button or test button on the ice maker module itself — press and hold for 3 to 10 seconds until you hear a chime or the ice maker begins a test cycle. For Samsung and LG models, check the freezer door or the ice maker arm for a test/reset button. After a reset, allow 24 hours for the ice maker to produce a full batch of ice.
Small or hollow ice cubes usually indicate low water pressure or a partially clogged water inlet valve. The ice maker is filling but not getting enough water to make full-sized cubes. Check that the water supply line is fully open and not kinked. If water pressure to the fridge is adequate, the inlet valve screen may be clogged with mineral deposits.
Allow 24 hours after turning on or resetting an ice maker before expecting ice production. The freezer must reach -18°C, and the ice maker goes through several freeze cycles before producing a full bin. New refrigerators or ice makers that have been off for an extended period take up to 24 hours for the first batch.
The freezer must be at or below -12°C (10°F) for the ice maker to function — ideally -18°C (0°F). If the freezer is warmer than this, the ice maker will not complete its cycle. Check the freezer temperature with a thermometer and adjust the setting if needed.
Ice maker leaks are most often caused by a cracked water supply line, a faulty water inlet valve that drips between cycles, or a frozen and clogged fill tube that is causing overflow. Turn off the water supply to the fridge and call a technician if you see water pooling under or inside the freezer.
If the issue is the water inlet valve, supply line, or ice maker module itself — yes, repair is usually worth it. These parts cost $50 to $150 and are straightforward for a technician to replace. If the issue is a damaged ice maker assembly on a fridge that is 12+ years old, weigh the repair cost against the refrigerator's remaining value.
