This active carbon filter refreshes the air when your range hood is set to recirculate. Replace a saturated filter to restore effective odor reduction and maintain a more comfortable cooking space. What it does:

• Adsorbs cooking odors in recirculating operation
• Helps maintain fresher indoor air when venting back into the room
• Restores odor-removal performance when the old filter is saturated
• Typical signs it's time to replace: persistent cooking smells or diminished odor reduction

• One activated carbon filter

• Disconnect power to the hood before servicing
• Remove the metal grease filter(s) to access the charcoal filter
• Release the old filter from its clips/bayonet mount and install the new filter in the same orientation until it locks
• Charcoal filters are not washable; replace when saturated

• For hoods configured for recirculation; not used when vented to the outdoors

The Water Filter is an OEM part for Bosch refrigerators. This part removes impurities and contaminants from the water supply to your appliance. This part ensures that the water and ice dispensed by your refrigerator are clean, taste fresh, and are free of common waterborne particles and substances. 

Over time, the water filter can become clogged with sediments and contaminants, reducing its effectiveness and potentially affecting the taste and quality of the water and ice. Regular replacement is essential for maintaining optimal performance.

Symptoms of a bad Water Filter include:

• Unpleasant taste or odor in the water or ice
• Decreased water flow to the dispenser or ice maker
• Visible particulate matter in the water or ice cubes

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

This insulating part is a factory replacement insulation panel that helps limit heat transfer and dampen noise inside the appliance cabinet for reliable operation and quieter cycles. Use it to restore proper thermal/sound control after damage or removal. What it does

• Replaces worn, torn, or missing insulation to reduce heat loss and help maintain internal temperatures.
• Dampens operational noise from motors and pumps for quieter appliance cycles.
• Protects surrounding components from direct heat exposure.
• Helps the appliance reach and hold proper operating conditions more efficiently.

• One insulating panel as shown.

• Inspect surrounding clips and fasteners; replace any that are damaged before installing the new panel.
• Position the panel carefully to avoid compressing or folding the insulation; secure per original mounting points.
• Disconnect power before accessing the appliance interior and follow all safety precautions.
• If adhesive was used on the original, use heat- and appliance-rated adhesive or fasteners as specified by the manufacturer.

This operating module is the user-interface control board assembly that manages cycle selection and user commands, helping your appliance respond correctly to button presses and display status information. It restores control functionality when the interface fails. What it does:

• Receives and processes user inputs from buttons or touch controls so the appliance can start and change cycles.
• Sends signals to the main control and other components to execute selected functions.
• Can resolve symptoms like unresponsive controls, missing or incorrect display information, or inability to select cycles.
• Works as the interface layer between the user and the appliance's main electronics.

• Disconnect power to the appliance before starting work to avoid shock or damage.
• Handle the module carefully and avoid touching exposed circuitry; use anti-static precautions where possible.
• Some disassembly of the control panel is typically required; keep fasteners and small parts organized.

The Motor-Fan is an OEM component specifically designed for Bosch refrigerators. It circulates air to optimize internal temperatures.

The motor-fan works continuously to push cool air from the freezer compartment and direct airflow throughout refrigerator shelves and bins. Strategically positioned vents help regulate temperature variances. 

Symptoms of a bad motor-fan include:  

• Inconsistent or fluctuating temps from section to section
• Frost or condensation building up unusually fast 
• Abnormal sounds like grinding or squealing during the operation
• Complete lack of airflow

Causes can be a failed motor bearing, compromised fan blades off balance, or blockage preventing free rotation.

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

• Common signs it's needed: cracked or broken housing, loose fit, rattling, or the attached part won't stay in place/intermittently works
• Direct-fit replacement built to match the original form and connection points

• Disconnect power to the appliance before service; shut off gas or water if applicable
• Access location varies by model; refer to your service manual and document wire routing/fastener locations
• Transfer any screws, clips, seals, or wiring from the original if they are reused
• Do not overtighten fasteners into plastic; check for a secure, even fit before reassembly

This is an electrical on/off switch used to control power to an appliance circuit. It replaces a failed switch so controls respond normally and the appliance can be powered on and off safely. What it does

This sensor monitors operating conditions inside the appliance and reports to the control so cycles run correctly and safely. When the sensor fails, the control may receive inaccurate feedback, leading to irregular performance. What it does:

• Detects key conditions inside the appliance and sends a signal to the control
• Helps the control regulate heat and cycle progress
• Failure symptoms can include erratic cycle times, poor heating performance, or sensor-related error messages
• Can prevent the appliance from starting or completing a cycle if readings are out of range

• 1 sensor

• Disconnect power before servicing; shut off water supply if applicable
• Access the sensor and note wire orientation before removal
• Ensure any sealing surface is clean and the sensor is seated properly; check for leaks after reassembly where applicable

This NTC temperature sensor measures appliance temperature and sends resistance-based readings to the control board so the appliance can monitor and regulate heating or cooling for proper operation and cycle control. What it does:

• Detects internal air or component temperature and converts it to a resistance signal for the control board.
• Helps the appliance maintain correct temperatures during heating, cooling, or drying cycles.
• Commonly linked to symptoms like incorrect temperature, extended cycles, or temperature-related error codes.
• Failsafe for sensing — a damaged sensor can cause erratic operation or prevent normal cycle completion.

• Disconnect power before accessing or replacing the sensor to avoid shock or damage.
• Handle the sensor and wiring gently; avoid bending or crushing the sensing tip.
• Verify proper connector seating and routing to prevent pinching; confirm electrical continuity with a multimeter if needed.
