Three Jobs, One Complaint A JennAir kitchen frequently has two of these — the one in the refrigerator and a 15-inch undercounter machine — and they fail for different reasons, so it is worth knowing which one you are standing in front of. An ice maker does three separate things: - **Fills** — water arrives in the mold.- **Freezes** — it turns to ice.- **Harvests** — the ice lets go and drops into the bin. Any one of those failing produces exactly the same outcome, which is why "no ice" is such an unhelpful sentence and why almost every page about it starts with a parts list. There is a better first move, and it takes a second. ## Look for Water in the Mold Open it and look at the tray or mold where the ice forms. - **Water and no ice** — the fill worked, the freeze did not. Look at the temperature, the airflow, and whether the compartment is genuinely cold.- **Ice made and still sitting there** — the harvest did not release. That is a heated element and a mechanical push, and either can be the reason.- **Nothing at all, dry** — the water never arrived, and the problem is in the plumbing rather than the machine. That one observation moves you from "it is broken" to "it is one of three things", and two of those three have free causes at the top of them. ## The Free Causes, In Order **The arm or the switch.** Every ice maker has a way of being told to stop. A shut-off arm knocked upward by a package, or a switch turned off during a clean and never turned back on. It is the most embarrassing answer and it is genuinely common. **A frozen fill tube.** The little tube that carries water into the mold runs through a cold space, and it freezes solid. Production stops completely. Clearing it costs the visit and no part at all, and it is one of the most frequent things we find. **The filter.** A cartridge past its life restricts flow. The mold never fills properly, the ice comes out small and cloudy, and eventually it stops. Change it before you assume anything mechanical. **The supply valve.** Behind or under the cabinet, on the line feeding the appliance. It gets closed during plumbing work and never reopened. Free to check with a torch. **The grille — on an undercounter machine.** These breathe through the toe kick. In a kitchen where the cabinetry was finished after the appliances went in, that grille is regularly closed off by a kick panel fitted flush or a run built tight around it. The machine then works exactly as designed in a space that was not, and makes noticeably less ice with nothing at all wrong inside it. ## Quality Goes Before Quantity An ice maker in trouble usually makes **worse** ice before it makes **less**, and less before it makes none. Cloudy, soft, small cubes are the early warning. At that point the answer is nearly always a filter and a clean. Waiting until the bin is empty means paying for a repair instead of a service, and the two are not close in price. If your ice has changed character in the last month, that is the moment. ## Why Cloudy Ice Is About Flow A machine that makes clear ice does it by freezing water in layers, slowly, so that dissolved air and minerals get pushed ahead of the advancing ice rather than trapped in it. Slow the flow down — scale in the path, a tired filter, a partly blocked line — and the layering breaks down. The air and the minerals stay where they are. You get cloudy ice, and it is softer because it is full of them. So cloudy ice is a **water** message, not a temperature one, and the fix is a clean and a cartridge rather than a thermostat. ## The Undercounter Machines Want Cleaning Twice a Year More often than the manual assumes, for two South Florida reasons: the water, and the cabinet. A proper clean is not wiping out the bin. It is the reservoir, the distributor, the surface the ice actually forms on, the pump and its path, and the bin sensor that decides when to stop. Deposit collects in every one of those, and the machine slows down gradually enough that nobody notices until it is a service call. The blunt version: **most ice machine calls in this city are a cleaning that was left too long.** A cleaning is cheaper than a visit. A pump is dearer than both. Please do not use a household descaler. This appliance makes something you put in a glass, and the products made for it are made for that reason. ## What to Have Ready When You Call The model number. Whether there is water in the mold. When it was last cleaned — that last one settles more of these than anything else. And, if it is an undercounter machine, whether it is indoors or out. We repair this equipment across Miami-Dade, Broward and Palm Beach. --- **[Read full article: Fill, Freeze, Harvest: Which Half of Your Ice Maker Has Stopped](https://jennairmiami.support/blog/jennair-ice-maker-not-making-ice/)**
