Symptoms
- Cubes are half-formed or oddly shaped
- Some cube slots produce ice, others don't
- Shape has changed noticeably from before
- Fill level appears uneven when watched during a cycle
Likely causes
- CommonUneven or insufficient water fillLow water pressure or a partially clogged filter can under-fill certain cube slots.
- CommonFreezer not level, causing water to pool unevenly in the trayA tilted unit can cause water to settle more in some slots than others before freezing.
- PossibleEjector mechanism timing slightly offIf ice is ejected too early or the mechanism is worn, cubes can come out partially formed.
- Less commonOld or worn ice maker moldYears of use can warp or wear the tray itself, changing the ice shape produced.
What to do
- Check freezer temperature and confirm it's at 0–5F for proper freezing time.
- Use a level to check that the freezer sits evenly, adjusting feet if needed.
- Replace the water filter if due, since flow issues can cause uneven fills.
- Watch a full cycle if possible to see whether the fill and freeze look even before ejection.
- If cubes are consistently malformed despite good fill and level, the ejector timing or tray itself may be worn.
- Consider replacing the full ice maker assembly if the unit is older and shape problems persist.

When to call a pro
If cubes remain misshapen after checking level, temperature, and filter, an appliance technician can evaluate the ice maker mechanism.
