The short answer
When an apartment-size refrigerator stops producing ice, examine one thing first: the fill tube has frozen over. It is both the likeliest cause and the cheapest to rule out. Next on the list: the freezer is not cold enough to trigger a harvest. Nothing here needs a panel off until the last item.
What you observe
- The bin or the trays are empty and stay empty — Whether it stopped abruptly or tailed off already splits the list.
- Ice production stopped suddenly rather than tailing off — A blocked tube is binary; a failing part tails off.
- Ice cream in the same freezer has gone soft — The whole compartment is warm, not just the ice maker.
- Cubes are small, hollow or only part-formed — The mould is being underfilled rather than not filled.
- NEAR MISS — ice forms but tastes or smells wrong — A filter or storage question, not a production one. Different page.
Causes, most likely first on this unit
- The fill tube has frozen over — First where a run of good ice stopped abruptly. The fill tube carries a dribble of water to the mould, and if the mould overfills once, or the freezer runs colder than usual, that dribble freezes in the tube and seals it for good.
- The freezer is not cold enough to trigger a harvest — Ranked here because a warm freezer stops ice production before any water part is at fault.
- The water supply to the cabinet is off or half-closed — Ranked here because a supply problem is free to check and accounts for a large share of these calls.
- The bail arm or level sensor is in the off position — Last, and slightly embarrassing when it is the answer — which is exactly why it is on the list.
Check in this order, and why
- Look into the fill tube at the back of the freezer with a torch — A plug of clear ice there explains the whole fault.
- Check that the freezer is genuinely hard-frozen — A freezer holds food safely at 0 °F (−18 °C) or below.
- Find the shut-off valve and confirm it is fully open — A part-open valve gives small or hollow cubes, not no cubes.
- Look at the bail arm and clear anything leaning on it — Arm up means off. A stacked freezer holds it up all the time.
What an owner can safely check
- Establish whether it stopped suddenly or faded over weeks — Abrupt means a blockage or a switch; gradual means a restriction.
About 5 min
- Inspect the fill tube with a torch and thaw any plug gently — Warm water on a cloth. Never a screwdriver or a flame.
Tools: torch, clothAbout 30 min
- Confirm the freezer is hard-frozen before anything else — A freezer holds food safely at 0 °F (−18 °C) or below.
Tools: thermometerAbout 30 min
- Trace the supply line to its valve and open it fully — Then discard the first batch of ice before judging.
About 15 min
- STOP HERE before opening the ice maker or any water fitting — Pressurised water and live terminals are where an 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. Leave the freezer door switch wired as you found it: it cuts the evaporator fan for a reason, and defeating it puts a spinning blade behind an open door.
When to call a technician
Call once the temperature is confirmed good, the supply is proven open and nothing is frozen in the fill path — what is left is an electrical part in a wet place, which is a meter job. Call sooner if the cabinet is also failing to hold temperature — then ice is the symptom, not the fault. Call immediately if you find water standing on or near an electrical connection.

What this page does not cover
This page is written for the brand and the cabinet class, not for one family or model line. Where a family- or model-specific page exists for your unit, it is the more specific answer and you should start there. Deliberately absent: fan and defrost identifiers, wiring colours and capacity figures, which differ between the top-freezer and all-refrigerator families.
