# Most Refrigerator Noises Are Normal. Four Are Not

An Electrolux refrigerator making noise is nearly always a refrigerator doing its job out loud, and the useful question is not what it sounds like but when it happens.

## What a healthy cabinet does

**Water running.** Refrigerant moving through the evaporator, and meltwater running down to the drain pan during a defrost cycle. Both sound like a tap left half open somewhere behind the wall.

**Popping and cracking.** Plastic liners and shelving contracting as the cabinet cools and expanding as it warms. Loudest in a new appliance and after a door has been open a while.

**Short bursts every couple of hours.** The ice maker filling, then the harvest, then cubes dropping into the bin. In a quiet kitchen with a column in it this genuinely startles people, and it is the machine working.

**A fan running on after everything else stops.** Normal on anything with electronics to cool.

## The one that usually turns out to be real

A rhythmic tick, warble or whirring that **stops the moment the door opens**.

That is ice catching the evaporator fan blade. The fan is wired to stop when the door opens, so a fan problem falls silent exactly when you go to investigate it — which is why the trick is to hold the door switch in with a finger and listen with the door open.

It is worth acting on, and not only for the noise. A blade fighting frost is also a defrost problem wearing a fan problem's clothes, and the cooling complaint arrives a few weeks later.

## The second: the condenser fan

A drone rather than a tick, continuous rather than intermittent, and usually louder from the front of the cabinet than from inside it.

In coastal air the condenser fan collects a fine grit that puts it out of balance, and behind a trim kit that vibration travels straight into the joinery. Cleaning it is the same visit as cleaning the coil, and it is the cheapest thing anybody does to refrigeration in this region.

## Why built-in cabinets sound worse

A freestanding refrigerator stands in air. Most of what it makes goes into the room and disperses.

A counter-depth cabinet scribed into an opening, or a column behind a trim kit, is in contact with the structure on three sides. The joinery takes the vibration and re-radiates it, so a noise that would be completely unremarkable in a freestanding unit becomes the reason somebody calls a repair company.

We check for contact points before assuming a mechanical failure. Packing a cabinet off a side panel, or easing a unit that is bearing on its scribe, has ended more of these calls than any part we have ever fitted.

## What to tell us

Not the adjective. The timing.

Continuously, or in bursts. Only with the doors shut, or with them open too. Every couple of hours, or all the time. Since delivery, or since last month.

"It has been like this since it was installed" and "it started three weeks ago" are completely different conversations, and the second one is the sentence worth telling us first.
