The short answer
A Cooluli cannot make ice, and that is a limit of the technology rather than a fault. A thermoelectric cooler pulls the interior a certain distance below the room temperature; in a normal room that does not reach freezing, so there is no ice maker to fail and a tray of water will not set. If you need ice, you need a compressor-based appliance.
What you are actually seeing
- A tray of water placed inside never freezes — Means: on-page
- Ice brought from a freezer melts inside the unit — Means: on-page
- There is no ice maker, no mould and no water connection anywhere on the unit — Means: on-page
- The interior is cool but nothing frosts or ices up — Means: on-page
- Frozen items thaw when stored in the unit — Means: on-page
- The interior is not even cool — Means: different-fault — Go to: cooluli-refrigerator-cooling-failure
- Water collecting in the bottom of the interior — Means: different-fault — Go to: cooluli-refrigerator-water-leak
- Body: Match what you see before changing anything. A tray of water placed inside never freezes. Ice brought from a freezer melts inside the unit. There is no ice maker, no mould and no water connection anywhere on the unit. The interior is cool but nothing frosts or ices up. Frozen items thaw when stored in the unit. Some near-miss symptoms belong on a different page: The interior is not even cool points at a cooling or power fault, covered on cooluli-refrigerator-cooling-failure; Water collecting in the bottom of the interior points at condensation rather than melted ice, covered on cooluli-refrigerator-water-leak.
Causes, ranked for this machine
- The unit is thermoelectric and cannot reach a freezing temperature in a normal room — Why this rank: First because it is the complete answer: there is no ice-making mechanism to diagnose and no part that has failed
- The unit has no ice maker, no mould and no water supply — Why this rank: Worth stating plainly, because owners looking for a fill valve or a harvest arm will not find one
- The room is warm, so the interior is further from freezing than the owner expects — Why this rank: The cooling difference is relative to ambient, so a warm room moves the interior further away from ice
- Frozen items placed in the unit thawing, which is normal behaviour — Why this rank: This is the most common way owners discover the limit, and it is not a malfunction
- A cooling fault making the unit even warmer than its normal limit — Why this rank: Last, and it belongs on the cooling page rather than here
- Body: Ranked for a thermoelectric personal cooler, which has no compressor and no refrigerant and cools only relative to the room it stands in. Most likely: The unit is thermoelectric and cannot reach a freezing temperature in a normal room. First because it is the complete answer: there is no ice-making mechanism to diagnose and no part that has failed. Next most likely: The unit has no ice maker, no mould and no water supply. Worth stating plainly, because owners looking for a fill valve or a harvest arm will not find one. Third: The room is warm, so the interior is further from freezing than the owner expects. The cooling difference is relative to ambient, so a warm room moves the interior further away from ice. Fourth: Frozen items placed in the unit thawing, which is normal behaviour. This is the most common way owners discover the limit, and it is not a malfunction. Fifth: A cooling fault making the unit even warmer than its normal limit. Last, and it belongs on the cooling page rather than here.
What to check, in order
- Confirm the unit is thermoelectric and has no ice maker or water connection
- Measure the interior temperature with a thermometer and compare it with the room
- Judge whether the unit is performing normally for its type before looking for a fault
- Move anything that must stay frozen into a freezer
- Body: Each check rules out the causes above it. First, confirm the unit is thermoelectric and has no ice maker or water connection. Second, measure the interior temperature with a thermometer and compare it with the room. Third, judge whether the unit is performing normally for its type before looking for a fault. Fourth, move anything that must stay frozen into a freezer.
Checks you can safely make yourself
- Look over the whole unit for an ice maker, a mould or a water inlet, and check the rating plate for the unit type — Tools: torch — Time estimate: a few minutes
- Put a thermometer inside and read it after several hours, alongside a second thermometer in the room — Tools: two thermometers — Time estimate: several hours
- Compare the difference you measured with what the unit achieved when it was new, if you know it — Tools: notepad — Time estimate: a few minutes
- Move any frozen food to a freezer and use the unit for drinks, cosmetics or items that only need to be cool — Tools: none — Time estimate: a few minutes
- If the interior is barely below the room temperature, treat it as a cooling complaint instead and work through those checks — Tools: none — Time estimate: a few minutes
- Body: Checks an owner can make with the unit unplugged or simply observed. Step one: Look over the whole unit for an ice maker, a mould or a water inlet, and check the rating plate for the unit type. Tools: torch. Time: a few minutes. Step two: Put a thermometer inside and read it after several hours, alongside a second thermometer in the room. Tools: two thermometers. Time: several hours. Step three: Compare the difference you measured with what the unit achieved when it was new, if you know it. Tools: notepad. Time: a few minutes. Step four: Move any frozen food to a freezer and use the unit for drinks, cosmetics or items that only need to be cool. Tools: none. Time: a few minutes. Step five: If the interior is barely below the room temperature, treat it as a cooling complaint instead and work through those checks. Tools: none. Time: a few minutes.
Safety first
Safety
Unplug the unit before cleaning the interior. Do not rely on this unit to keep food safe: a refrigerator holds food safely at 40 °F (4 °C) or below, and a thermoelectric cooler in a warm room often cannot reach that. A refrigerator holds food safely at 40 °F (4 °C) or below. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. fridge-40f unplug-before-service
Where the owner fix ends
There is nothing to call about when the only complaint is that the unit does not make ice, because it was never able to. Call, or replace the unit, only if the interior is barely cooler than the room, which is a cooling fault rather than an ice fault.
