# U-Line wine cooler not cooling

### Measure the bottles, not the display

Put a thermometer in a bottle of water inside the cabinet, close the door and leave it twenty-four hours. It is the maker's own method, and on this appliance it settles more than the display can: the display shows what the control believes, and the control is reading a sensor that may be the whole problem.

### Ask how much of the cabinet is wrong

Five of U-Line’s seventeen wine models hold two zones independently, each with its own sensor and its own set point. A single zone drifting is a much smaller job than the phrase the call usually arrives as, and establishing which it is takes a thermometer and a day rather than a technician and an hour.

### Wine is less forgiving than food

A refrigerator that runs two degrees warm is a nuisance. A wine cabinet that runs five degrees warm for a season is doing something you cannot undo, which is why this page is less relaxed about small drifts than the refrigerator one, and why the measurement matters more than the display.

Showroom mode

Ruled out first because it is free and because it produces exactly this. Degree symbol flashing, display lit, refrigeration off.

A zone sensor

A dual-zone cabinet has a sensor per zone and the control logs them separately — the third and fourth thermistors exist precisely for these cabinets.

The door and its seal

Wine cabinets are opened less and judged harder. A marginal seal costs a degree or two permanently, and on wine that matters.

Condenser and airflow

Same first answer as everywhere else on this make, and it is right often enough to be worth checking before anything is opened.

The sealed system

Last. On a cabinet worth several thousand dollars this repair is usually still worth doing, which is a different conversation from the one on a small beverage center.

Check the degree symbol

Flashing rather than steady is showroom mode, and the refrigeration is off deliberately.

Measure both zones separately

A bottle of water and a thermometer in each. One zone out and both zones out are different repairs.

Look at the inside of the glass

Misting on the inside of a glass door is a seal question, and it is the cheapest thing on this list.

Clear the grille

A wine cabinet under a counter in a Miami kitchen is doing continuous work and cannot do it through a blocked grille.

One zone, or the whole cabinet

What it usually means

One zone warm, the other right

The whole cabinet drifting

Bottles warmer than the display claims

### The top shelf is warmer than the bottom.

In a single-zone cabinet a gradient is normal and is usually deliberate — it is why reds go high and whites go low. A gradient that has grown, or that has appeared where there was not one, is a different matter.

### It is humming louder than it used to.

Worth mentioning on a wine cabinet specifically. More vibration usually means the refrigeration is working harder, which is the same story as this page from the other end.
