The short answer for these models
Ice production on URLC cabinets depends on three things in series: water reaching the mould, the compartment being cold enough to freeze it, and the harvest mechanism clearing it. This family is one model number, which makes the scope of this page unusually clear. Almost every complaint on this family resolves to the first two, which are checkable without opening anything.
The observations that separate this fault from its neighbours
- A buzz or hum from the ice compartment with nothing produced — The valve or the module is being asked to work and cannot. A repeated buzz on a timer is the tell.
- It stopped after the cabinet was moved or the filter changed — The strongest clue on this page, because it names the work that disturbed the water path.
- The maker runs but the bin stays empty — Ice is being made and is not arriving: a jammed ejector, a blocked chute, or cubes fusing before they reach the bin.
- Cubes are cloudy or have a white core — Mineral content and a fast freeze rather than a fault. It says more about the water supply than about the machine.
- NEAR MISS — the whole freezer section is soft and the ice is melting — That is a cooling failure, and the ice is just the first thing to show it. Use the cooling page instead.
What to suspect, in order, on this family
- The supply side: tap, line and connection — Ranked first because a cabinet that is plumbed in has a whole length of pipework outside itself, and every one of those points fails more often than the ice maker does. Confirm water arrives before suspecting anything inside.
- Water inlet valve or a frozen fill tube — Second, because it is the boundary between the plumbing and the machine, and it fails in a way that mimics both. A valve that will not open gives a dry mould; a tube that is partly iced gives a hollow cube.
- How cold the ice compartment actually is — Third, and it is the cause that produces the complaint of ice that is slow rather than absent. The control waits for a temperature it is not getting.
- The ejector, the module and the shut-off arm — Fourth. Mechanical failure of the module is real but uncommon, and a shut-off arm or sensor held up by a lump of ice in the bin looks exactly like it for free. Check the bin before the module.
- The control side — Last. A control fault is diagnosed by ruling out water and temperature, and it is the only item here that usually needs a meter.
What to check first, and why that order
- Empty the bin and look at the ice already in it — Fused lumps, hollow cubes or nothing at all each name a different cause, and the bin is free to inspect.
- Reset the shut-off arm or clear the sensor path — Done second because it is the cause most often found after the bin is emptied.
- Check the fill tube for an ice plug — A plug is cleared with warm air and patience. Never with a tool — the tube deforms and then leaks.
- Confirm the supply side — Tap, line and connection, in that order, so that a dry mould is explained before parts are considered.
- Measure the compartment last — Placed last because it takes hours to do properly and the quicker checks usually answer the question first.
Safety first
Safety
Power off and water off before the ice maker is disturbed; a capacitor can hold a charge after the power is off. Sharp metal edges sit inside the ice compartment on cabinets of this build, and the mould release can be hot immediately after a harvest cycle. Ice that thaws and refreezes is a temperature warning, not just a nuisance: a freezer holds food safely at 0 °F (−18 °C) or below, and fused cubes say the compartment is not holding it.

When to call a technician
The boundary on these models is the fill tube. Bin, arm, supply valve, line and temperature are owner-side; the module, the mould heater and the wiring to them are a service call because they need the maker out and a meter on. Call immediately if you find water anywhere it should not be.
