Noises

2.9.1

Normal noises

►

Compressor noise

The droning noise is generated by the compressor. It may briefly
become slightly louder when the compressor switches on. When the
compressor switches off, a rattling noise may be heard.

►

Flowing noises

The bubbling or gurling noise is generated by the refrigerant as it
flows through the tubes.

►

Switching noises

The clicking noise is caused by the temperature controller or
a solenoid valve.

►

Air-flow noises

If the appliance features an internal fan (No Frost), the air flow inside
the appliance may generate a rushing noise.
