# U-Line condensation on the door or the outside

### Establish which side of the glass it is on

External condensation on a humid day is documented as normal and clears as the room dries. Condensation on the inside of a glass wine door, or damp reaching the joinery around a built-in unit, is the appliance and is worth acting on.

### Outside is weather, inside is the appliance

Water on the outside of a cabinet on a humid day is documented as normal and clears as the room dries. It is not a comfortable answer and it is the right one more often than not in this climate — the same appliance in Denver would not do it.

### Inside a glass door is a different question

Misting on the inside of a wine cooler door means warm moist air is reaching a cold surface, and on a sealed cabinet the only route in is the door. That is a seal or an alignment, and it is the cheapest repair on this site to correct and one of the most expensive to leave, because the same moisture is going into the cabinet.

Room humidity

The maker's own answer for external condensation, and in a Miami August it is usually the right one. Nothing to repair.

A seal that has taken a set

Warm moist air meeting a cold surface at the gap. The classic cause of misting inside a glass door.

A door slightly out of alignment

The seal is fine and is not being pressed onto the cabinet evenly.

A cabinet running colder than it needs to

The colder the glass, the more it will condense. Worth checking the set point against what the cabinet is actually for.

Work out which side of the glass it is on

Outside is very often the room. Inside is the appliance.

Check the room

The maker's answer for external condensation is excessive humidity, and that it dissipates as humidity falls. In August here, that is usually the whole story.

Paper-test the door

Misting inside a glass door is warm air meeting cold glass at a gap.

Look at the joinery around the unit

Damp reaching the cabinetry is worth acting on regardless of what is causing it.

Outside is weather, inside is the appliance

What it usually means

Beads on the outside of the door

Misting on the inside of the glass

Damp on the cabinetry around it

### It only does it when it rains.

Then it is the room, and the maker says so. Nothing to repair.

### The cabinet next to it is getting damp.

Worth a look, regardless of cause. Persistent damp against joinery does damage that lasts longer than the appliance will.
