The short answer
Before condemning the icemaker, establish whether it is being given water and whether it is being given cold. On this family one of those two is the answer far more often than not. The arm or the sensor that tells the mechanism the bin is full is the other frequent answer, and it costs nothing to check. Only the water valve and the mechanism need a technician, and both sit behind the rest of the list. The table above is the boundary of this page: if your rating plate is not on it, you are on the wrong family.
How it presents
- The bin is empty and the mechanism never cycles — No movement at all over a day. Points at supply, at the shut-off arm or at power to the module rather than at the mechanism.
- Hollow or crescent-shaped cubes that are part frozen — Classic partial fill. The tray is being given less water than it expects, which is a supply restriction rather than a mechanism fault.
- Cubes are small but properly formed — A short fill rather than a blocked one. Suspect a restriction in the filter or a partially closed supply tap.
- The mechanism runs on a cycle but the bin never fills — Production far slower than consumption, which points at the compartment temperature rather than at the mechanism.
- NEAR MISS — water is leaking outside the cabinet — A supply leak is its own page and its own urgency; deal with the water before the ice.
The ranking for this platform
- Fill tube frozen — Top of the list here. The tube crosses from warm into cold and the last of each fill sits in that crossing; freeze it once and the mechanism harvests nothing from then on.
- Shut-off arm or bin sensor holding the mechanism off — The cheapest fault on the page. An arm lifted by stored food, or a beam broken by frost, reports a full bin to a mechanism looking at an empty one.
- Freezer not cold enough to trigger a harvest — The mechanism has its own thermostat and will not eject until it is satisfied, so a compartment a few degrees warm gives you no ice rather than slow ice.
- Water filter blocked or overdue — Restriction rather than blockage, and it shows in the shape of the cubes rather than in their absence. Also the last thing anyone thinks of.
- Water inlet valve or icemaker module failed — Last on the list. Both are real failures and both need testing rather than guessing, which is where this page hands over.
Follow the water, in this order
- Check the shut-off arm is down, or the bin sensor is clear — An arm held up by a stored bag stops production completely and takes a second to rule out.
- Dispense water at the door, if the cabinet has a dispenser — Water at the door proves the supply reaches the cabinet, which cuts the list in half immediately.
- Trace the supply line to the valve behind the cabinet — Look for a closed tap and for a kink where the cabinet was pushed back. Last on the list because it means moving the machine.
What to do before the panel comes off
Safety
Isolation comes before inspection here. Unplug the appliance or trip its breaker, and assume every capacitor inside is still holding what it was holding.

When this stops being owner work
Stop at the point where the supply path is proven good. Everything after that is electrical testing inside a cold cabinet, which is service work on this roster.
