What Loud Running Noise Means
Liebherr answers a noisy commercial cabinet with two questions and one statement. Is it standing firmly on the floor, and is it making nearby furniture or objects vibrate — and then, plainly, that noises caused by the refrigerant circuit cannot be avoided. That last part is not a brush-off; it is the manufacturer setting expectations.
Common Causes of Loud Running Noise
- An unlevelled cabinet transmitting vibration into the floor
- Contact with benches, shelving or neighbouring equipment
- Clearances around the housing closed up during a kitchen rearrangement
- Refrigerant-circuit noise, which Liebherr states cannot be entirely avoided
🔧 One Safe Check You Can Try
Level the cabinet properly on its adjustable feet, and check what it is touching — a stainless bench, a stack of trays or a neighbouring unit will amplify a hum that the appliance alone would not produce. Liebherr also specifies a clearance around the housing, and closing that gap is a common cause of new noise after a kitchen is rearranged.
⚠ Why You Shouldn't Go Further Than That
- A noise that is genuinely new and mechanical — grinding, rattling from the fan, a compressor that labours on start — is a different report from the ones Liebherr lists as unavoidable, and describing it accurately is what gets it taken seriously.
- Commercial cabinets are heavy, and shifting one to chase a noise without planning it is how backs and floors get damaged.
