Call (904) 442-8210. # Sub-Zero ice maker not making ice — Orange Park and Clay County Your ice maker has stopped in Orange Park. The freezer compartment gets checked before the ice maker does, and that order is what saves you an unnecessary part. Source: https://subzerorepairorangepark.com/service/ice-maker-not-making-ice/ --- **Symptoms this page covers:** The mold fills but the cubes never release; Cubes come out hollow, cloudy or half the normal size; Ice production drops off over weeks rather than stopping all at once; The bin has a solid slab in it instead of loose cubes; No water reaches the mold at all; Ice tastes of the freezer, or of nothing but old plastic. **What gets checked, in order:** Confirm the freezer compartment is actually holding temperature before touching the ice maker; Check the fill valve and the supply line for restriction or a closed shut-off; Read the mold heater and the ejector cycle rather than replacing the whole assembly on suspicion; Inspect the condenser for pet hair and dust loading, which changes everything downstream; Look at the drain and defrost path for melt-and-refreeze evidence in the bin; Check the filter age and the line pressure at the shut-off, not just at the appliance. An ice maker that has stopped is the call we take most often, and it almost always arrives with a theory already attached: the ice maker is broken and it needs a new one. Sometimes that is right. More often the ice maker is the messenger rather than the fault. It is the most temperature-sensitive process in the cabinet, because it will not begin a harvest until the mold reaches its release temperature, so it is the first thing to visibly stop when something upstream of it drifts. Fitting a new assembly on suspicion buys a new part and the same symptom — which is why the compartment gets checked before the ice maker does. ## Temperature comes before the ice maker The freezer compartment gets checked before anything is opened up. An ice maker is a thermostatically triggered device: it will not begin a harvest until the mold reaches its release temperature. A compartment sitting a few degrees warmer than it should produces exactly the symptom described on the phone — the mold fills, the water freezes eventually, and nothing ever comes out of it. That is not an ice-maker fault. It is a refrigeration fault that happens to show up in the ice first, because ice is the most temperature-sensitive thing the cabinet does. Replacing the ice maker in that situation buys you a new part and the same problem. On a built-in with two sealed systems, the freezer side can be struggling while the fresh-food side reads perfectly normal, which is why so many people tell us "the fridge is fine, it is just the ice." Often the fridge is fine. The other half of the machine is not. ## Fill, freeze, harvest, drain Once temperature is confirmed, the sequence has four stages and the cube itself tells you which one failed. **Fill.** Hollow cubes, short cubes, or a mold that is only part full point at water delivery: a partially closed shut-off behind the cabinet, a filter that was last changed several years ago, a kinked line pushed against the wall when the unit was slid back in, or a fill valve that is opening but not passing its rated flow. We check pressure at the shut-off as well as at the appliance, because a restriction upstream reads the same as a failed valve if you only measure in one place. **Freeze.** Cubes that are cloudy or take far too long point back at compartment temperature and, behind that, at airflow. **Harvest.** A full, properly frozen mold that never ejects is a mold heater or ejector problem. This is the one stage where the ice maker itself is genuinely at fault, and it is a smaller share of these calls than most people expect. **Drain.** A solid slab in the bin is not an ice-maker failure at all. It is melt-and-refreeze, and it means something is warming the bin between cycles — usually a defrost or drain issue, sometimes a door that is not sealing. ## The condenser question Before we leave, the condenser gets looked at whatever the fault turns out to be. In a house with dogs, cats, or an air handler running nine months of the year, the condenser behind the upper grille collects a felt of hair and dust that it was never designed to breathe through. The unit compensates quietly for months. Then it stops compensating, and the ice is the first thing you notice. ## When the assembly really is the answer There is a version of this call where the ice maker itself is genuinely at fault, and it is worth describing so the estimate makes sense when you see it. A mold that fills correctly, freezes to a proper cube in a compartment we have measured and confirmed, and then never ejects has a harvest problem: the mold heater, the ejector mechanism, or the switch that tells the control the cycle finished. That is a bounded repair on a discrete part, and it is the one situation where replacing the assembly is the cheapest correct answer rather than a guess. The part is ordered against the model and serial from the plate inside the cabinet, because components are revised within a model designation and two units that look identical in a kitchen can take different assemblies. Common wear items ride on the van; an assembly ordered to a serial number adds days rather than hours, and we tell you which of the two you are in before you commit. One honest limit: if the supply into the house is the problem — a failed shut-off, house plumbing, or a filter housing that is not ours — we will say so and stop there rather than working outside what we are competent to touch. ## What a visit costs A flat diagnostic fee covers the visit and is credited toward the repair if you go ahead with it. You get a written figure before any part is ordered, and nothing is ordered until you approve it. Refrigerant work is handled by EPA Section 608 certified technicians. Parts are genuine OEM. --- **Contact.** Doctors Lake Refrigeration, Orange Park, FL 32073. Phone (904) 442-8210. Monday – Friday 08:00–18:00; Saturday 09:00–16:00. Closed Sunday.
