Parts for Thermador KBUDT4875E/01: Duct Assy Parts

This Bosch filter removes contaminants and improves water taste. The filter should be changed every six months for best performance. Simple installation requires no special tools. Measures approximately 13.25" x 2.5" x 2.5".

The Fan Motor is an OEM replacement part for Bosch refrigerators. It circulates cold air inside the insulated liner maintaining precise temperatures. Unhindered airflow locks in freshness. 

Causes of a bad fan motor involve enduring years of constant rotation which stresses motor windings and bearing surfaces beyond rated lifetimes. Vibration and ambient heat accelerate breakdowns.

Symptoms of a bad fan motor include:  

• Loss of desired cooling capacity as air fails to circulate    
• Temperature fluctuations that compromise perishables  
• Audible grinding or rattling from within the fridge's interior
• Failed fan blades detaching pose potential fridge hazards

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore models.

This fan blade replaces a damaged or worn blower blade to restore proper airflow and reduce noise. It helps the appliance circulate air efficiently so cooling and ventilation perform as intended. What it does:

• Moves air across the evaporator/heatsink or within the appliance cabinet to support cooling and ventilation
• Restores full airflow when the original blade is cracked, warped, or missing
• Helps reduce rubbing, vibration, and unusual fan noise caused by damaged blades
• Prevents motor strain that can occur when an imbalanced or broken blade is used

• Disconnect power to the appliance before beginning any repair
• Handle the blade carefully to avoid bending the impeller fins
• Inspect the motor shaft, set screw, and mounting hardware; replace any damaged fasteners

This P.C. board receiver replaces the appliance's receiver control board to restore signal processing between the user controls/remote and the main control system. It helps return normal control response and status signaling. What it does:

• Receives and processes signals from the control panel or remote interface
• Communicates those signals to the main control system so cycles and functions start
• Can cause symptoms such as no response to button presses, no LED/display updates, or intermittent control operation
• Works with other control electronics to manage user inputs and status feedback

• Always disconnect power to the appliance before servicing to avoid shock or damage
• Handle the board carefully; avoid static discharge and contact with components
• Verify connector orientation and seating; do not force connectors

This is a replacement mounting bracket designed to secure internal components in compatible Bosch appliances. It restores proper alignment and support for attached parts to reduce wobble, rattling, or misalignment. What it does:

• Provides secure attachment point for panels, assemblies, or hardware inside the appliance
• Restores proper alignment when a bent, broken, or missing bracket causes vibrations or loose parts
• Helps stop rattling, shifting, or intermittent contact caused by a damaged support bracket
• Matches OEM fit to maintain factory spacing and clearances when installed correctly

• One mounting bracket

• Install only with the appliance powered off and disconnected from its electrical supply
• Use proper fasteners and torque to avoid stripping threads or cracking surrounding components
• Verify orientation and mating surfaces before tightening; replace any damaged screws or clips

This P.C. board receiver replaces the appliance's receiver control board to restore signal processing between the user controls/remote and the main control system. It helps return normal control response and status signaling. What it does:

• Receives and processes signals from the control panel or remote interface
• Communicates those signals to the main control system so cycles and functions start
• Can cause symptoms such as no response to button presses, no LED/display updates, or intermittent control operation
• Works with other control electronics to manage user inputs and status feedback

• Always disconnect power to the appliance before servicing to avoid shock or damage
• Handle the board carefully; avoid static discharge and contact with components
• Verify connector orientation and seating; do not force connectors

This bi-metal defrost thermostat controls the refrigerator's defrost cycle by opening or closing the circuit to the defrost heater, helping remove frost buildup and protect the heater from overheating. What it does:

• Opens the defrost heater circuit when the evaporator reaches the correct temperature to stop heating
• Closes the circuit at colder temperatures so the heater can run during a defrost cycle
• Helps prevent excessive frost buildup that can reduce cooling performance
• Commonly replaced when the defrost cycle fails to start or will not end properly

• One defrost bi-metal thermostat

• Disconnect power to the appliance before servicing to avoid electrical shock
• Located near the evaporator/heater assembly; access may require removing panels or the evaporator cover
• Handle carefully to avoid bending terminals or damaging the sensor element
• Test for continuity before replacement
