Common solutions for: Sub Zero Refrigerator is noisy or loud

01 - Sub Zero 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 obst...ructions.

02 - Low Water Pressure from House Supply
The home may have insufficient water pressure. The water inlet valve supplies water to the water dispenser. The water inlet valve requires a minimum of 20 psi to function properly. Check the water flow and test the pressure to determine if it is at least 20 psi.
03 - Sub Zero 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.

06 - Sub Zero 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.
