Ice Maker Not Making Ice?
8 Common Causes and What to Check
The bin is empty, the cubes come out small and hollow, or the ice maker hums and nothing happens. Here is what stops a refrigerator ice maker, what you can safely check yourself, and when it needs a technician.
Quick answer: A refrigerator ice maker not making ice usually has one of three problems: it's switched off or its shutoff arm is up, the freezer is warmer than 0°F, or water isn't reaching it because of a clogged filter, a closed valve or a frozen fill tube. Check the switch and the freezer temperature first, then the water. If the mold stays dry with the water on, call a technician.
Still no ice? A technician can often come the same day in Chino and nearby cities. $75 diagnostic, applied to the repair.
Below are the eight causes we find most often across the Inland Empire and the San Gabriel Valley when an ice maker is not making ice, in the order to check them, and when to book refrigerator ice maker repair in Chino.
The eight causes
1. Ice maker switched off or the arm is up Setting
Ice makers are easy to turn off by accident. Many stop when the wire shutoff arm on the side is raised, which also happens when the bin is full or a box in the freezer pushes it up; others have a switch on the ice maker or an Ice Off setting on the display. If the arm is up or Ice Off is lit, the ice maker won't run, however good the water and the temperature are.
Signs it's switched off:
- The wire arm is raised, or an Ice Off light is on
- Something in the freezer, or a full bin, is pressing on the arm
- The ice maker stopped after the freezer was cleaned or reorganized
Can you fix it yourself? Yes, and it's the first thing to check. Lower the arm or switch the ice maker on, then allow a few hours for the first cubes; after a restart some ice makers take a full day to reach normal output.
2. A new refrigerator that needs more time Setting
A refrigerator that was just installed has to pull its freezer down to temperature before the ice maker will cycle, and the first batches fill the bin slowly. GE says a new refrigerator usually takes about a day to start making ice, and LG allows 12 hours to two days for the first batch and two to three days to fill the bin.
Signs it just needs time:
- The refrigerator was delivered or plugged in within the last day or two
- The freezer doesn't feel fully cold yet
- The water line and the filter are new
Can you fix it yourself? Yes: wait. Make sure the water valve is open and the filter is seated, then give the freezer time to get cold.
3. Freezer warmer than 0°F Temperature
An ice maker only starts a cycle once its mold is cold enough, so a warm freezer means slow ice or none. Samsung's ice maker guide (opens in a new tab) says the freezer needs to be at 0°F or less to produce ice, and Whirlpool recommends 0 to 5°F. A door left ajar, a worn gasket, frequent opening or a cooling fault lets the freezer drift warmer, and ice production is the first thing to slow down.
Signs it's the freezer temperature:
- Ice cream is soft, or a freezer thermometer reads above 0°F
- Ice production slowed gradually rather than stopping overnight
- Frost is building up on the freezer's back wall
Can you fix it yourself? Partly. Set the freezer to 0°F, close the door firmly and keep the gasket clean. If the freezer won't get cold, see freezer not freezing.
4. Water valve closed, line kinked or filter clogged Water
No water in the mold means no ice. The household shutoff valve may be partly closed, the line may be pinched behind the refrigerator, or the filter may be clogged or not locked in place after a change. Low flow leaves its own clue: Whirlpool notes that low water pressure can cause small or hollow cubes and slow or no ice, and Samsung lists 20 psi as the minimum for its refrigerators.
Signs it's the water supply:
- The mold is dry, or the cubes are small, hollow or half-formed
- The water dispenser is slow too
- The filter is more than six months old, or was just replaced
Can you fix it yourself? Yes.
- Open the shutoff valve all the way; it's usually under the sink or behind the fridge.
- Unplug the fridge, pull it out and check the line for kinks.
- Reseat or replace the filter, then run water through the dispenser to clear the air.
- Push the fridge back without pressing it tight to the wall, which can pinch the line.
If the door gives no water either, see refrigerator water dispenser not working.
5. Frozen fill tube Water
The fill tube carries water from the inlet valve into the ice maker's mold, passing through the cold freezer wall on the way. If the valve weeps a little between fills, or the pressure is so low that water trickles in, the water freezes in the tube and seals it. Mineral scale at the end of the tube can also deflect the stream so it misses the mold.
Signs it's the fill tube:
- Ice visible in the tube or at the opening above the mold
- The valve buzzes during a fill, but no water reaches the mold
- Icicles or a lump of ice behind the ice maker
Can you fix it yourself? Sometimes.
- Turn the ice maker off and unplug the refrigerator.
- Find where the fill tube enters the ice maker, usually at the back of the mold.
- Melt the ice with warm water from a turkey baster, with a towel underneath to catch the runoff.
- Plug the fridge back in and turn the ice maker on.
A tube that refreezes within days points to a leaking inlet valve, which is a technician repair. If water is overflowing into the bin or onto the floor, see refrigerator leaking water.
6. Ice jammed in the mold or the bin Ice
Sometimes the ice is made but can't get out. A cube caught in the ejector arm stops the cycle partway, and cubes that melted and refroze, after a power outage or a door left open, fuse into a clump that blocks the arm or the dispenser auger. LG notes that partially melted ice that refreezes sticks together, and suggests throwing out large clumps.
Signs it's jammed ice:
- Cubes are in the mold, but the ice maker never drops them
- Ice in the bin is fused into a block
- The ice maker stopped after a power outage
Can you fix it yourself? Yes, usually.
- Turn the ice maker off before you reach in; the mold can be hot right after a cycle.
- Free a stuck cube with a plastic utensil, never a knife.
- Empty the bin, throw out the clumps, then wash, dry and reseat it fully.
- Turn the ice maker back on.
7. Failed water inlet valve Part
The inlet valve at the back of the refrigerator opens on the ice maker's signal to fill the mold. A valve with a burned-out coil stays shut, and one whose inlet screen is clogged with sediment or scale lets only a trickle through. If the ice maker cycles and the supply is open with the tube clear, but no water arrives, the valve is the likely failure.
Signs it's the inlet valve:
- The ice maker cycles, but the mold stays dry
- A buzz or hum from the back with no water flowing
- Ice and dispenser water stopped at the same time with the supply valve open
Can you fix it yourself? No. Testing the valve's coils takes a meter, and replacing the valve means working where the water supply meets the refrigerator's wiring.
8. Ice maker module or control fault Part
If water arrives and the freezer is cold, but the ice maker never ejects a batch, the ice maker itself has failed: its motor, its thermostat or the control that runs its cycle. Many models have a test or reset button that forces a cycle, and the owner's manual shows where it is. If a test cycle doesn't sweep the cubes out and refill the mold, the module is the problem.
Signs it's the ice maker module:
- Cubes freeze in the mold but never drop, even after a reset
- Nothing moves or hums during a test cycle
- An error code on the display that points to the ice maker
Can you fix it yourself? Sometimes. A reset or a test cycle is worth trying. Replacing the module is a part matched to your model, and testing the controls behind it takes a meter.
Ice maker not dropping ice vs. not dispensing ice: what's the difference?
The two sound alike but point to different parts. Not dropping means cubes form in the mold and stay there: a jammed ejector, a failed module or a freezer too warm for the cycle to finish. Not dispensing means the bin has ice but nothing comes out of the door: clumped cubes blocking the auger, a frozen chute, the dispenser lock, or a failed auger motor or switch.
Check the bin first. If it's full and the door won't dispense, break up the clumps; if it's empty with cubes stuck in the mold, the problem is the ice maker itself.
Why is my ice maker making small or hollow cubes?
Small, hollow or half-formed cubes mean the mold isn't getting a full fill. The usual reasons are a clogged filter, a partly closed shutoff valve, low household pressure or a reverse osmosis system, and an inlet valve with a clogged screen. Some older ice makers also have a fill-adjustment screw on the module; the manual shows whether yours does. Full-size cubes that come too slowly point instead to a warm freezer or a slow cycle.
What to check yourself first
- Check the switch and the arm. Lower the shutoff arm or turn the ice maker on, and make sure nothing presses on the arm.
- Check the freezer temperature. Set it to 0°F and confirm it with a freezer thermometer.
- Check the water. Open the supply valve fully and make sure the line behind the fridge isn't kinked.
- Reseat or replace the filter. A clogged or loose filter starves the ice maker first.
- Clear jams. Empty clumped ice from the bin and free any cube stuck in the ejector arm.
- Reset the ice maker. Use the test or reset button your manual describes, or unplug the fridge for a few minutes.
One safety note: turn the ice maker off and unplug the refrigerator before you reach into the ice maker or work on the fill tube, since the ejector arm can move and the mold can be hot right after a cycle. Close the water shutoff valve before you disconnect any line.
When to call a technician
- The mold stays dry with the water valve open and a new filter in place
- The fill tube freezes again within days of thawing
- A test cycle doesn't sweep the cubes out or refill the mold
- The valve buzzes, but no water reaches the ice maker
- The freezer won't hold 0°F
Sounds like yours? A technician can diagnose it at home in Chino and nearby cities, often the same day. $75 diagnostic, applied to the repair.
Era Service repairs ice makers in French-door, side-by-side, top-freezer, bottom-freezer and built-in refrigerators, in the door or in the freezer, across the Inland Empire and the San Gabriel Valley, often the same day in Chino and nearby cities. Hard water is part of the story here: City of Chino wells average about 248 mg/L hardness (opens in a new tab), which is very hard, and over time mineral scale builds up on the inlet valve's screen and at the end of the fill tube.
Good to Know
Ice Maker Not Making Ice: FAQ
A refrigerator ice maker usually stops because it's switched off or its arm is raised, the freezer is warmer than 0°F, or water isn't reaching it through a clogged filter, a closed valve or a frozen fill tube. Ice jammed in the mold or bin comes next. When the water and the temperature are right and a reset doesn't help, the inlet valve or the ice maker module has failed.
An ice maker that isn't filling with water has a blocked water path: a closed or partly closed supply valve, a kinked line, a clogged or loose filter, a frozen fill tube or a failed inlet valve. If the valve buzzes but no water arrives, the fill tube is often frozen; if there's no sound at all with the supply on, suspect the valve or the ice maker's control.
After a power outage, a refrigerator ice maker can stop because cubes melted and refroze into a clump that jams the ejector or the bin, or because its cycle needs a reset. Empty and wash the bin, free any stuck cubes, then reset the ice maker with its test or reset button, or unplug the refrigerator for a few minutes. Expect new ice within a few hours and normal output within a day.
On a Samsung refrigerator, first make sure the Ice Off icon isn't lit and the ice bucket is fully seated. Samsung says the freezer must be at 0°F or less and the water pressure at least 20 psi. To reset, press and hold the Test button, usually behind the ice bucket, until it chimes, which can take up to 10 seconds; if it doesn't, cut the power for 2 minutes and try again.
On a Whirlpool refrigerator, Whirlpool's support guide says to set the freezer between 0 and 5°F, confirm the water line is connected with the valve fully open, and check that a recently replaced filter is locked in place. To reset, hold the ice maker's reset button for a few seconds, or unplug the refrigerator for 1 minute if there's no button.
On an LG refrigerator, unlock the panel by holding Lock for three seconds, then turn the ice maker on with the Ice On/Off, In-Door Ice, Cubed Ice or Craft Ice button. LG allows 12 hours to two days for a new fridge's first batch. Its test button, on the lower-left side or the front of the ice maker, is held for 3 seconds; without one, cut the power for at least 3 minutes.
Still no ice? We'll get the ice maker filling again.
