Thermador Refrigerator is noisy or loud
If your Thermador refrigerator is noisy or loud, start with the fans: check the evaporator fan blade behind the freezer back panel and the condenser fan under the rear of the unit for obstructions or bent blades and try turning them by hand. Next rule out low household water pressure, which can make the water inlet valve squeal or chatter during ice fills. A failing evaporator fan motor often makes a loud, grinding sound that gets worse when the door is opened, and a worn damper control assembly can click or whine as it opens and closes to route cold air. Also make sure the refrigerator is level to eliminate vibration or rattles, and listen near the ice maker for a failing drive motor or module. Whether your fridge is making loud noise, the refrigerator making grinding noise, or the ice maker making noise, enter your model number on RepairClinic.com to find the exact replacement part for your model along with diagrams and repair guidance.
01 - Thermador 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.

Highly Likely
02 - Low Water Pressure from House Supply
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 - Thermador 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.
Highly Likely
04 - Thermador 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.
Highly Likely
05 - Refrigerator not level
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 - Thermador 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.
