The water works but there is no ice. What does that tell me?

A great deal. Water reaching the dispenser proves the supply line, shutoff valve, inlet valve and filter are all passing water. The fault is therefore inside the ice-making side — temperature, the ice maker's own control, the fill arm, or a blockage — rather than in the water supply.

What temperature does a freezer need to be to make ice?

Whirlpool's guidance is 0 to 5°F, which is -17 to -15°C. Be careful with figures you find quoted online — some pages give 0°C, which is a different number entirely and comes from documents written for other markets.

How long should a new ice maker take to make ice?

Longer than most people wait. A newly installed or newly restarted ice maker has to bring an empty mould down to temperature before the first cycle completes, so judging it after an hour tells you nothing.

Should I change the water filter?

If it is more than six months old, yes — Whirlpool recommends that interval. But a working dispenser makes a fully clogged filter unlikely, since the same filter feeds both.

No Ice but the Water Dispenser Works? That Narrows It a Lot

A working water dispenser is diagnostic information, not just a detail. It proves the supply line is open, the shutoff valve is on, the inlet valve is operating and the filter is passing water — because all of those sit upstream of both the dispenser and the ice maker.

So the entire water-supply half of the usual troubleshooting list is already ruled out before you start. Whatever is wrong is on the ice-making side.

That is worth being explicit about, because most guidance for this problem opens by telling you to check the water supply and change the filter. If water comes out of the door, you have already tested both.

Start with the things that are not faults

Two of the most common causes are not failures at all.

The ice maker is switched off. Whirlpool names this directly as a common reason an ice maker produces no ice: it was turned off, usually by accident. The control might be a switch inside the freezer, a slider on the ice maker itself, or a setting on the door panel depending on your model.

The fill arm is raised. Models with a mechanical arm use it to detect a full bucket — when ice pushes the arm up, production stops. A bag of frozen peas resting against it does exactly the same thing, permanently. If your model has an arm, look at where it is sitting.

Neither of these costs anything, and between them they account for a large share of ice makers declared broken.

Then the temperature, and mind the number

This is the most common real cause, and it comes with a trap.

Whirlpool’s guidance is that the freezer must be between 0 and 5°F — that is −17 to −15°C — for ice production.

You will find pages quoting 0°C for this. That is not the same number, it is not the US figure, and it comes from documentation written for other markets. A freezer sitting at 0°C is barely at freezing point and will not run an ice maker properly. If you set your freezer by that figure you will conclude the ice maker is broken when the appliance is simply too warm to make ice.

Measure with a thermometer rather than trusting the panel display, and let it settle for a few hours before reading it.

Note the direction of the fix, too. If your freezer is warmer than that range, the answer is colder — but resist the instinct to go far below it. Running a freezer well under its target causes its own problems, and Frigidaire explicitly warns that settings below the recommended point can cause frost.

Then look for a blockage

Ice that partially melted — during a power cut, a door left open, or a defrost cycle running long — refreezes into a solid bridge. The ice maker keeps producing, the bucket keeps filling, and nothing comes out of the chute.

Unplug the refrigerator, take the bucket out, and break the mass up by hand. Check the chute as well. This looks like a dead ice maker and is not one.

Give it time before judging

An ice maker that has been switched off, refilled, or reset has to bring an empty metal mould down to temperature before the first cycle completes. Judging it an hour later tells you nothing.

This is the same mistake people make after clearing demo mode — checking too early, seeing no result, and concluding the fix failed. Leave it overnight.

The filter, for completeness

Whirlpool recommends replacing the water filter every six months, and a restricted filter genuinely can starve an ice maker.

But apply the logic from the top of this article: the dispenser and the ice maker are fed through the same filter. If water is flowing normally from the door, a fully clogged filter is unlikely. A partially restricted one is still possible — the ice maker needs a specific fill volume per cycle and is less tolerant of low flow than a dispenser you can simply hold down for longer.

If your filter is overdue, change it anyway. Just do not expect it to be the answer when the water side is visibly working.

Where this sits with the other water faults

The refrigerator’s water system produces several complaints that share components:

No water from the dispenser either. Different problem, and the supply side is no longer ruled out — see a dispenser that will not dispense.
Water pooling inside the fridge. Usually the defrost drain rather than the water supply: water inside the cabinet.
A buzz roughly every fifteen minutes. GE documents that as the ice maker reaching for water that is not there — covered in what refrigerator noises mean.

That last one is worth knowing about, because it is the case where the ice maker is trying and failing, and the appliance is telling you so audibly.

Where most of these end

Most of these end at a switch, an arm, a temperature setting, or a lump of ice — none of which cost anything.

The genuine part failures on the ice-making side, once the water supply is proven by a working dispenser, are the ice maker’s own module or its fill valve. Both are model-specific parts, and the route to the right one is your model number in a retailer’s fitment tool rather than a part number matched to a symptom.
