Whirring or Ticking Inside My Liebherr Refrigerator: Normal or Not?

A quiet kitchen makes every sound from a refrigerator stand out. Liebherr units use fans, a compressor and a defrost cycle, and each of them makes a few noises in everyday operation. The trick is knowing the difference between a usual sound and one that needs attention.

Sounds that are usually fine

• A soft hum or whoosh as the compressor or fan starts and stops.
• A light tick or crack as plastic and metal expand and contract with temperature changes.
• A gentle gurgle or trickle as refrigerant moves.
• A short burst of louder air when a door is opened, or after a fresh load of groceries.

Sounds worth checking

• Rattling. Often a loose bottle, a bin touching the cabinet wall, or a unit that is not level.
• Constant whirring or buzzing. May mean a fan that is dragging, has ice around it, or has a failing motor.
• Repeated ticking that does not fade. A fan blade may be touching frost or a loose piece of insulation.
• Loud grinding. Please stop and call us. Do not keep the unit running for days.

Quick checks

Move items away from the back and sides, and make sure shelves and drawers are fully seated. Check that the refrigerator is level, and see that it does not touch the cabinet beside it. Then listen again. If the sound stops when you open the door, a fan in the cold section is likely involved.

Booking a visit

We check fans, mounts, defrost parts and the compressor area, then give you a written price. Visit our refrigerator repair page or the service area page to schedule. Repairs include a 30-day workmanship warranty.
