# Miele one wine zone is warm

### The fastest diagnosis is the code

Check the cabinet is level and that it has air where it stands. A built-under unit boxed into a run with no ventilation cannot lose its heat, and it is a five-minute check that occasionally answers the whole complaint.

### One good zone proves the expensive half

A single compressor and a single condenser serve the whole cabinet. If one zone is holding its temperature correctly, both of those are working, and whatever is wrong is downstream: a thermistor, a zone fan or a damper. That is the cheap end of this appliance and it is worth saying on the phone.

### Two things to rule out first

Whether the cabinet is level, and whether it has anywhere to lose its heat. A built-under unit boxed into a closed run cannot, and it will never hold a setting however good its parts are.

A thermistor

Reading one zone wrongly.

A zone fan or damper

Which is what one warm zone usually means.

Airflow where the cabinet stands

Not a part, and worth ruling out first.

The sealed system

Only when every zone is wrong at once.

And the other is perfect

What it usually means

The upper zone warm, the lower fine, or the reverse

A zone that will not come down to its setting

Both zones drifting together
