# Dacor refrigeration making a new noise

### What to do in the next ten minutes

Open the door and listen: a noise that stops immediately is the evaporator fan, because it switches off with the door. Put a hand on the cabinet front and on the joinery beside it to feel whether the sound is being carried by the cabinetry. Note when it happens — constantly, in bursts, or only after the compressor starts.

### Why built-in cabinets sound different

A freestanding refrigerator stands on its own feet in the middle of a room. A column is screwed into a run of joinery that behaves like a soundboard, and the same compressor that would be inaudible elsewhere can hum through an entire kitchen. That is an installation correction rather than a repair, and it is one of the more satisfying visits there is.

### Which noises to act on

Scraping and knocking are mechanical and worth a prompt call. Humming and buzzing are usually contact or a fan and can wait for a convenient appointment. A noise that comes with a temperature change is not a noise complaint at all — it is a cooling problem that happens to be audible.

The evaporator fan is failing

Ice fouling the blade or a bearing gone dry. It is the commonest new noise, it stops when the door is opened, and it is worth catching before the cabinet stops cooling evenly.

The condenser fan or a loose panel

Behind the grille, where dust and a loose kick panel both produce a rattle that rises and falls with the compressor. Cheap to correct and easy to mistake for something serious.

The cabinet is touching the joinery

A panel-ready column transmits every vibration into the run around it. A shim that has dropped or a trim screw that has loosened turns ordinary compressor noise into a kitchen-wide hum.

Open the door and listen

The single most diagnostic second available on this problem, and it is free.

Feel the joinery, not just the appliance

Contact noise through cabinetry is loud, alarming and mechanically trivial.

Note the pattern

Constant, in bursts, or with the compressor. Each points somewhere different.

A click, a buzz or a rattle that was not there last month

What it usually means

A new noise is worth a call; a familiar one usually is not

Noise that stops when the door opens is the evaporator fan

Panel-ready cabinets amplify contact noise through the joinery

### It only does it at night.

It almost certainly does it all day as well, and the kitchen is quiet enough at night to hear it. That is genuinely useful information: it means the noise is constant rather than intermittent.

### Can I just live with it?

With a hum or a rattle, yes. With a scrape or a knock, no — those are mechanical and they get worse, and on refrigeration they usually take the cooling with them eventually.
