Possible Causes

How to Fix / Troubleshooting
Safety: Disconnect power before touching fans or moving the appliance.
Steps:
- 1. Level the appliance: Use a spirit level to check front-to-back and side-to-side. Adjust leveling feet until the unit is stable and does not rock.
- 2. Check rear components: Remove the rear cover and inspect the condenser fan, compressor, and tubing. Ensure no tubes are touching each other or the cabinet. Gently bend them apart if needed.
- 3. Inspect fan blades: Look for debris in the condenser fan or evaporator fan (inside the freezer). Clean and ensure blades are not rubbing against shrouds.
- 4. Tighten loose parts: Tighten any loose screws on panels, fan mounts, or brackets.
- 5. Replace noisy fan: If a fan motor is excessively loud or has play in the shaft, replace it with a Gaggenau-compatible fan motor.
