KitchenAid ice maker not working: the six things that stop it

No ice at all, and the tray is dry
Water never arrived. The supply line, the shut-off valve, the inlet valve and the water filter are the chain to check. A filter well past its service life restricts flow enough to stop the fill, and it is the most common single cause. Filters are also the easiest item to replace.
Hollow or undersized cubes
Water is arriving, but not enough of it per fill. That is a restricted supply rather than an absent one — a partially frozen line, a filter nearing the end of its life, or low household water pressure. The ice maker itself is working correctly.
A solid block instead of cubes
The mould is filling but not ejecting on schedule, so successive fills freeze together. That points at the ejector motor or the thermostat that decides when the ice is ready. It can also happen after a power interruption mid-cycle.
Ice made but never dispensed
The problem is downstream of production. The dispenser chute can ice over, particularly if the door is opened frequently or the bin has partially melted and refrozen. Clearing the chute resolves it; if it returns quickly, the door seal or the freezer temperature is worth checking.
The freezer is not cold enough
Ice makers need a freezer at the correct temperature to complete a harvest cycle. If the freezer has drifted warm, ice production is often the first thing you notice, before frozen food shows any obvious sign. Verifying freezer temperature is a sensible early step.
The arm or switch is in the off position
It sounds trivial and it happens constantly — a bail arm knocked upward by a tall item, or a paddle switch left off after cleaning. It costs nothing to check and it ends a fair number of service calls before they start.
Frequently asked questions
How long should a new ice maker take to start producing?
Typically a full day to reach steady output after installation or a filter change. Judging it after a few hours usually leads to an unnecessary call.
Should I turn the ice maker off when we go away?
Yes, if you will be gone more than a week or two. It stops the bin from fusing into a block and avoids stale ice.
