The short answer
On a Nuage refrigerator, the thermoelectric module is being asked for more than it can deliver is the usual answer when the unit runs but the cabinet is warm — not a failed compressor. This is a small personal cooler rather than a refrigerator in the appliance sense, and that shapes the order below. A cosmetic cooler lives in a bathroom or on a dressing table, which is the most humid and the most temperature-swung room in the house.
What you observe
- The cabinet is warm while the unit is plainly running — You can hear it working and feel air moving, but nothing inside is cold.
- It never stops — there is no quiet period at all — A healthy cabinet cycles. One that runs without a break is one that is never reaching its setpoint.
- One area is cold and the rest is not — Cold at the plate or the vent and warm at the door means an airflow problem rather than a cooling one.
- NEAR MISS — the unit is silent, dark and nothing is cold — No light, no fan, no hum means no power reaching it or a failed start component. That is a different fault and a different page; leave this one.
Causes, most likely first on this platform
- The thermoelectric module is being asked for more than it can deliver — Ranked first because this platform has no compressor at all — a solid-state module moves heat from the inside plate to a finned heat sink, and it can only hold the cabinet a fixed span below whatever the room is. Moisture, not mechanics, is what fails on this platform, and that is why this heads the list rather than sitting in the middle of it.
- Heat load the cabinet was never rated to shed — Warm surroundings shift everything: the run time climbs, the compressor never catches up, and a unit that was fine in the kitchen fails in a garage or a sunroom.
- The control set wrong, or the unit left in a showroom mode — Worth ruling out before anything else even though it rarely turns out to be the answer: a dial knocked to its warmest position, a unit still in the display mode a retailer uses, or a switch on a dual-zone cabinet set for the wrong compartment all present as "it will not cool".
Check in this order, and why
- First: put a hand on the rear heat sink and confirm its fan is moving air — It tests the number-one cause directly, it needs no tools, and a hot, still heat sink explains the whole complaint. In a bathroom the moisture is the story, so start with where the water is coming from.
- Second: read the temperature where the unit actually stands — Second, because it is the other half of the same question: the cabinet can only work against the air it is given.
- Third: read the control before you change it — Do it first only because it takes ten seconds; it is rarely the answer but it costs nothing to eliminate.
What an owner can safely check
- Clear the heat-sink fins and confirm the fan is turning — The fins are behind the rear grille. Dust bridging them is the single most common cause of lost cooling on this design.
Tools: vacuum, soft brushAbout 15 min
- Give the unit a hand's width of clear air on every side it needs it — Pull it out of the cutout or away from the wall and let it run. On an installed cabinet this alone often restores cooling within an hour or two.
About 10 min
- STOP HERE if the next step needs a meter on live terminals — Reading a defrost heater, a thermostat or a compressor winding means touching energised terminals behind a panel. That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the refrigerator or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Water and electricity are together in this appliance by design. Dry the floor before you work, never reach behind an energised cabinet, and stop at the first step that would put a meter on live terminals.
When to call a technician
Call once the checks above are clean, or immediately if you see oil on or under the cabinet — oil outside the tubing means the sealed system is open and every hour it runs after that costs more to put right. On this platform there is no refrigerant to lose, so the honest test is simpler: if the cabinet cannot hold a useful margin below a cool room with the heat sink clean, the module has failed and the repair is rarely worth its price on a unit this size.

What this page does not cover
This is a generalized page: one brand, one appliance, one symptom, and no assumption about which line you own. Specific pages beneath it cover individual families and models, and where one exists for your unit it is the better answer. Not covered here: service-manual procedures, electrical test values, part numbers and anything behind a panel.
