The answer first
A LHRiver that has stopped making ice is nearly always telling you about something upstream: a closed or kinked supply, a clogged filter, or a freezer that is not cold enough to freeze a mould in the time the cycle allows. The ranking below puts the checks in the order that settles most of these.
What you are seeing
- The bin is empty and stays empty — No cubes at all after a full day, with the unit otherwise running normally.
- Cubes are small, hollow or misshapen — That is a water-volume symptom, not an ice-maker failure — the mould is not filling.
- NEAR MISS — the freezer contents are soft and the cabinet is warm — Then the fault is cooling, not ice, and the cooling page is the one to read; ice is simply the first thing to fail when a freezer drifts warm.
What goes wrong here, in order
- The freezer is not cold enough to complete a cycle — An ice maker will not harvest until the mould reaches its release temperature. A freezer sitting a few degrees warm — because the door is opened constantly, the cabinet is overfull, or the seal is tired — makes ice slowly or not at all while the food inside still looks frozen. This is the one to start with: the way this unit gets used keeps its door open far more than a household unit, and ice is the first thing to suffer from that. LHRiver sells compact units through marketplace channels, where the cabinet is light, the door is light with it, and the gasket is the first thing that stops sealing.
- The water supply to the appliance — A shut-off valve left part-closed, a kinked line behind the unit, or a connection that was never opened after an installation will starve the ice maker without any other symptom. The unit keeps trying to fill and keeps getting nothing. Second here: it is upstream of everything else, so checking it first saves you from testing the rest against a supply that was never there.
- A clogged or overdue water filter — A filter at the end of its life drops the flow to a trickle. The ice maker fills partly, freezes what it has, and produces small hollow cubes or nothing at all — while the dispenser slows at the same time, which is the tell. Third in order: it matters, but the checks above it explain more of these calls on this brand.
- The ice maker is switched off or the arm is held up — Every ice maker has an off position — a wire arm, a lever, or a setting on the control. Loaded groceries push that arm up, a child presses the wrong button, and the unit obediently stops making ice with nothing whatsoever wrong. Next after those: it is worth a glance before anything else is opened up.
Work through it in this order
- Check whether the freezer is at 0 °F (−18 °C) or below — A freezer holds food safely at 0 °F (−18 °C) or below, and an ice maker needs roughly that to complete a harvest. Warmer than that and the ice is a symptom, not the fault.
- Trace the water line from the wall valve to the back of the unit — Look for a valve that is not fully open and for a kink where the line is pinched against the wall — both are common after a unit has been pulled out and pushed back.
- Fill a glass at the dispenser and watch the flow — A thin or stuttering stream is a filter or pressure problem; a strong steady one clears the whole supply path in a single test.
Steps you can take safely
- Clear the freezer vents, check the door seal and let the cabinet recover — Give it a full day at a lower setting before deciding the ice maker is at fault.
About 20 min
- Open the shut-off valve fully and straighten the supply line — Pull the unit forward far enough to see the whole run of the line rather than the last few inches of it.
Tools: adjustable spannerAbout 20 min
- STOP before pulling the ice maker assembly out — Removing it means disconnecting a harness and often working around a fill tube that has frozen. That is where the owner check ends.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Turn the water off at the wall valve before disturbing any connection, and never thaw a frozen fill tube with a flame or a heat gun; warm water and patience do it without melting the plastic around it.
When this becomes a service call
The owner's part ends at the fill tube. If the supply is open, the filter is new, the freezer is cold and the arm is down, the remaining causes all sit behind a panel with a live harness and a water connection side by side, which is a technician's job.

The scope of this page
Generalized information, written for the class rather than the model. Where a LHRiver family- or model-specific page exists beneath this one, that is the page to read for your unit. Deliberately absent here: service-manual steps, component part numbers and any specification that differs family to family.
