become slightly louder when the compressor switches on. When the
compressor switches off, a rattling noise may be heard.

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

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

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