The short answer
On a Landmark refrigerator an empty ice bin is usually a water-supply or a temperature problem rather than a failed ice maker. The first two checks below take minutes and need nothing but your eyes and a glass. Replacing the ice maker is the last resort on this list, not the first move.
What the fault looks like
- Cubes are small, hollow or misshapen — That is a water-volume symptom, not an ice-maker failure — the mould is not filling.
- Cubes have fused into one lump in the bin — Ice that melts slightly and refreezes has been through a temperature swing, which points at the freezer rather than at the ice maker.
- NEAR MISS — there is water under the unit as well as no ice — A leak with an ice fault usually means the supply line or the fill valve, and the water-leak page covers that path in detail.
Causes, most likely first
- 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. Landmark units are sold through general retail as second refrigerators, and a second refrigerator usually lives in a garage, a basement or a utility room rather than in a kitchen.
- 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. It follows immediately: 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.
Check in this order, and why
- 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.
The owner checks, step by step
- 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 anything comes apart
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.
Where the owner's part ends
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.

What is deliberately not here
Generalized information. This page covers ice production on Landmark refrigerators as a class, not on one family or model line; where a family-specific page exists it is the more precise answer and is linked above. Not covered here: part numbers for fill valves and modules, harness routing, and any figure that changes between families.
