Answer first
On a Winia refrigerator, running and still warm inside usually comes down to a stalled defrost cycle icing the evaporator, with a failed evaporator fan next. Most of the checks below are free and two of them need no tools, so work down the order rather than guessing at the expensive end of it.
What you actually observe
- The cabinet is warm and the unit is clearly running — The compressor note is there and the air inside is not cold, which is the whole of this page.
- The freezer still works and the fresh-food section does not
- NEAR MISS — the cabinet is silent and nothing is cold — That is a no-power or start-circuit fault, and it belongs on a different page.
Causes, most likely first on this platform
- A stalled defrost cycle icing the evaporator — First on a full-size electronic platform. This control adapts its defrost interval, and adaptive systems drift before they fail, so the coil ices over weeks while everything still sounds normal.
- A failed evaporator fan — Second, and the fastest to separate from the first: a cold coil with no air moving is the fan, and on this platform the fan is a serviceable part with a parts channel behind it.
- A thermostat or thermistor reporting a temperature that is not there — Third. The board acts on what its thermistors report, so a sensor reading a temperature that is not there shuts the compressor down early.
- A sealed-system or compressor fault — Fourth, and not an owner fix under any circumstances: it is the least likely of the four, which is why the three above come first.
Check in this order, and why that order
- Take the freezer rear panel into account: look for a sheet of frost rather than a dusting — A solid sheet over the coil area is a defrost problem, and it explains a warm cabinet with a running compressor. It goes first: top-ranked above, and free to rule out.
- Listen at the freezer for the fan, then hold the door switch in — Silence with the switch held means no air is moving, however cold the coil is. Second: the next cause in the ranking, and this check separates it from the first.
- Compare a thermometer inside the cabinet against what the control is set to — A refrigerator holds food safely at 40 degrees Fahrenheit, which is 4 degrees Celsius, or below; a freezer at 0 degrees Fahrenheit, which is minus 18 Celsius, or below. Third, once both checks above come back clean.
What an owner can safely check
- Empty the cabinet, unplug it and leave both doors open until everything inside is dry — Cold restored afterwards, then lost again over the following days, is a defrost fault confirmed.
About 60 min
- Listen for the fan with the freezer door open and the door switch held in — No tools. Silence here separates the two likeliest causes before anything is dismantled.
About 5 min
- Put a glass of water with a thermometer in it on the middle shelf overnight — A refrigerator holds food safely at 40 degrees Fahrenheit, which is 4 degrees Celsius, or below. A reading well off the set point tells you the control and the cabinet disagree.
Tools: thermometerAbout 30 min
- STOP HERE if the next step needs a panel off or a meter on live terminals — That is where an owner check ends on any sealed refrigeration system.
Before you take anything off
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 door switch wired as it is and do not defeat it to watch something run. If you find oil outside the tubing, stop: the sealed system is open, and refrigerant work is licensed work.
Where an owner check ends
Call once the coil is clean, the seals are good and the cabinet is still warm, because everything left is behind a panel. Call immediately if you smell burning or see oil at the compressor: oil outside the tubing means the sealed system is open, and every hour it runs after that costs more to put right. Parts for this platform exist through the brand's own channel, so a board or a sensor repair is a real option rather than a write-off.

What this page does not cover
This page is written for the Winia refrigerator as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is linked here, and it is the more specific answer. Not here: part numbers, wiring colours and panel sequences, which differ by family.
