How Do I Troubleshoot a Thermador Fridge Making Loud Noises?
By SubZero Appliance Repair
A loud Thermador refrigerator can be disruptive—and often signals that something’s not quite right. At SubZero Appliance Service, we understand how important a quiet, reliable appliance is in your home. If your fridge is making unusual noises, here’s how to troubleshoot the problem before it worsens.
Common Causes of Loud Refrigerator Noises
1. Fan Obstruction
A buzzing or grinding noise might indicate that the evaporator or condenser fan is being obstructed by debris or ice. Open the fridge and freezer doors—if the noise changes or stops, the issue is likely fan-related.
2. Loose or Vibrating Parts
Sometimes, a loud noise is caused by something simple, like a vibrating shelf, drawer, or rear panel. Check inside and behind your fridge for anything that might be rattling or out of place.
3. Ice Buildup
Frost near the fan area can lead to clicking or whirring sounds. This may point to a defrost cycle issue. Try unplugging and manually defrosting the unit. If the sound returns, you may need professional service.
4. Failing Compressor
If the noise is coming from the back and sounds like humming, knocking, or grinding, the compressor could be wearing out. Over time, this noise may get louder and indicate the need for a replacement.
5. Improper Leveling
A refrigerator that isn’t level can vibrate against the floor or nearby cabinets. Check the leveling legs and make small adjustments to ensure it sits evenly.
