When the ice bin stays empty, it's tempting to assume the ice maker itself has failed. Sometimes it has. But an ice maker depends on its own switch, a cold enough freezer, a steady water supply and the refrigerator's water valve, and a problem with any of them looks the same from the outside: an empty bin.
Work through these checks in order. Most of them take a few minutes and need no tools.
1. Is the ice maker turned on?
It sounds obvious, but an ice maker switched off by accident is easy to miss. Depending on the model, the ice maker may be switched on and off by:
- •A wire shutoff arm on the side of the ice maker. When the arm is raised, the ice maker stops. It can get pushed up by the ice bin or a bag of frozen food.
- •A rocker switch on or under the ice maker.
- •A setting on the control panel or in the display menu. Some models also have a lock or "ice off" setting.
Check all of them. If the ice maker was off, allow a day for the first full bin.
2. Is the freezer cold enough?
Ice makers need a cold freezer to freeze water in the mold and to trigger the harvest cycle. The freezer should be at 0 °F. Check with an appliance thermometer placed between packages for a few hours.
If the freezer is warm, the ice maker isn't the problem. Our guide to a refrigerator that isn't cooling covers that. An overpacked freezer that blocks the vents, a door that doesn't seal, or a freezer in a very hot garage can all cause slow ice.
3. Is water reaching the ice maker?
If your refrigerator has a door dispenser, use it as a test.
- •If the dispenser runs well, water is reaching the refrigerator and the valve is opening. The problem is closer to the ice maker: a frozen fill tube or the ice maker itself. Go to step 4.
- •If the dispenser is slow or dry too, the problem is upstream: the filter, the supply line, the shutoff or the refrigerator's water valve.
For an upstream problem, start with the easy fixes. Replace the water filter if it's overdue, and push or twist it fully into place, because a filter that isn't seated can stop the flow completely. Then make sure the shutoff valve feeding the refrigerator is fully open and the line behind the unit isn't kinked. If the refrigerator was moved recently, a kinked line is a likely cause.
In very hard water, a clogged filter, a scaled water valve or an old saddle valve on the supply can all cut the flow. Our guide to hard water in ice makers and fridge valves covers those, along with reverse-osmosis systems that don't deliver enough pressure.
4. Is the fill tube frozen?
The fill tube carries water from the valve into the ice maker mold. If it freezes, the ice maker cycles but no water arrives. Look at where the tube enters the ice maker, usually at the back. Ice built up around the opening suggests it's frozen.
To thaw it, unplug the refrigerator or turn off the ice maker, and use a hair dryer on low setting, held a safe distance away, or a warm, damp cloth. Keep water away from the electrical parts. Don't use sharp tools.
A fill tube that keeps freezing usually has a cause: a water valve that drips after it closes, low water pressure that lets the flow trickle, or a freezer that's too cold near the tube. That needs diagnosis.
5. Is the ice maker jammed?
Look in the mold and bin.
- •Cubes stuck in the mold or ice fused into a block in the bin can stop the ice maker. Remove the bin and break up the clump.
- •Ice built up around the ejector arm can jam it. Let it thaw.
- •The bin may not be seated properly, which on some models stops the ice maker.
If the ice maker makes a grinding noise, or the ejector arm stops partway through its rotation, the motor or gear may have failed.
Problems with the ice itself
- •Small, hollow or thin cubes usually mean low water flow: a clogged filter, low pressure or a scaled valve.
- •Cloudy ice comes from air and dissolved minerals trapped as the water freezes. It's common with hard water and isn't a fault.
- •Ice that tastes or smells stale often means the ice has been sitting a long time, or the filter is overdue. Empty the bin, wash it, and replace the filter.
- •Ice in the bin clumped into a block can come from a door that isn't sealing, frequent power loss, or a dispenser flap that isn't closing.
When to call a technician
Call for service if:
- •The dispenser works but the ice maker doesn't fill, after checking the fill tube.
- •Neither the dispenser nor the ice maker gets water after replacing the filter and checking the supply line.
- •Water keeps dripping into the ice maker or freezer after the fill ends, which suggests a leaking valve.
- •The ice maker makes grinding noises or stops mid-cycle.
- •Ice builds up repeatedly in the ice compartment of a door-mounted ice maker. This has been widely reported on some Samsung French-door refrigerators.
On many refrigerators the ice maker is replaced as a single module rather than repaired part by part, so the diagnosis mostly comes down to confirming whether the ice maker, the valve or the supply is at fault. Our ice maker repair page covers built-in ice makers and standalone ice machines. If you're finding water on the floor rather than a shortage of ice, see our guide to a refrigerator leaking water.
Frequently asked questions
How long does a new ice maker take to make ice?
It varies by model, but it often takes most of a day to produce a full bin. Discard the first few batches of ice after installation or after a filter change.
How much ice should a refrigerator ice maker make?
It depends on the model. Many built-in refrigerator ice makers produce a few pounds a day, and the specification sheet for your model gives the figure. After a party or a hot weekend, expect the bin to take a day or so to refill.
Can I use the refrigerator without the ice maker working?
Yes. Turn the ice maker off and, if possible, close the water supply valve so the water valve doesn't cycle without anything to fill.
