If your Gaggenau refrigerator is noisy or loud, start by checking the fans and airflow since loose or obstructed blades are the most common cause. Open the freezer and hand-spin the evaporator fan behind the rear panel, and inspect the condenser fan under the back of the cabinet for debris or rubbing. Next, rule out low house water pressure, which can make the water inlet valve squeal or chatter when the ice maker tries to fill; compare flow at the kitchen faucet. A failing evaporator fan motor often produces loud noise, especially when the door is opened, and usually requires replacement. A noisy damper control assembly that opens and closes to feed cold air to the fridge can also be the culprit as it wears. Don’t overlook simple vibration from an unlevel cabinet—adjust the front legs or rollers. Less commonly, the ice maker drive motor or module can get loud during cycles and may need the ice maker assembly replaced.

01 - Gaggenau Refrigerator Fan Blade
If the refrigerator is noisy or loud, especially when one of the doors are opened, either the evaporator or condenser fan blade may be at fault. First, check out the evaporator fan blade in the freezer behind the back panel. Try turning it by hand. If the fan blade does not turn freely, check to see if the blade is rubbing against something or if something is caught in the blade. Additionally, check the condenser fan blade in the back underside of the refrigerator to determine if it has any obstructions.

The home may have insufficient water pressure. The water inlet valve supplies water to the ice maker and low water pressure may cause the inlet valve to squeal or chatter. You can check the water flow at the kitchen faucet to help determine if the home's water pressure is sufficient or not.
Highly Likely
03 - Gaggenau Refrigerator Evaporator Fan Motor
When the evaporator fan motor in the freezer behind the rear panel fails, it often generates a lot of noise. This noise will be much louder when the refrigerator door is opened. If the evaporator fan is noisy, replace it.
04 - Gaggenau Refrigerator Damper Control Assembly
On many refrigerator models, a damper control assembly is used to control the air flow from the freezer compartment to the refrigerator compartment to maintain the appropriate air temperature. The assembly accomplishes this by opening and closing a small door. As the damper control assembly ages, the action of opening and closing the damper door can become noisy or loud. If the damper control assembly has become increasing noisy, you can replace the old assembly with a new one.
If the refrigerator is not level it can vibrate or rattle. Ensure the unit is level and stable on the floor. Most refrigerators' front legs or rollers are adjustable.
Highly Likely
06 - Gaggenau Refrigerator Ice Maker Assembly
If a refrigerator is making a loud noise near the ice maker when the unit is cycling, it's likely that either the ice maker's drive motor or motor module is beginning to fail. While some of the ice maker components, such as the drive motor or module, may be sold separately for select models, you may need to purchase and replace the entire ice maker assembly.
