# Bosch refrigerator making noise

### The fastest diagnosis is the code

There will be no code. What matters is when the noise happens: constantly, only when the compressor runs, or only when the doors have been open. Each points somewhere different.

### Where it comes from decides everything

- **Inside the freezer, changes with the door:** evaporator fan, probably hitting ice. Worth acting on.
- **Bottom or back:** condenser fan or compressor. Debris and dust are the common causes.
- **Changes when you lean on it:** levelling or contact with cabinetry. Free.
- **Gurgling, crackling, occasional clicks:** the appliance working.

### Noise plus drift

A new noise on its own is usually minor. A new noise together with a compartment that has drifted a degree or two is a diagnosis waiting to be made, and it is much cheaper made now.

The evaporator fan hitting ice

A scraping or ticking that changes when you open the freezer door. It is the noise worth acting on, because ice on the coil means a defrost problem behind it.

The condenser fan

A rattle or drone from the bottom or back. Often debris in the blade, sometimes a worn motor — and in this climate, sometimes corrosion.

The compressor working harder

A hum that has got louder over months. On its own it is not a repair; alongside a temperature drift it is a real clue.

The unit not level, or touching cabinetry

A buzz that changes if you lean on the unit. Free to fix and very common after a floor has been redone.

Normal operation

Gurgling as refrigerant moves, crackling as the cabinet expands, ice dropping into the bin, a click as the compressor starts. All expected.

Work out where it comes from

Open the freezer: if the noise changes immediately, it is the evaporator fan. From the bottom or the back, it is the condenser fan or the compressor.

Push gently on the cabinet

If the buzz changes, it is a levelling or contact problem and it costs nothing.

Pull the grille and look for debris

A bag, a bottle cap or a build-up of dust in the condenser fan blade will make a remarkable amount of noise.

Check the temperature at the same time

A noise on its own is often nothing. A noise plus a drift is a diagnosis, and it is worth booking.

What it usually means

A rattle or scraping that comes and goes

Loud humming that has got worse

Clicking every few minutes
