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".

A replacement heat exchanger that helps remove heat from the refrigerator cooling circuit so the appliance can maintain proper internal temperatures. Restores proper refrigerant flow and supports consistent cooling performance. What it does:

• Circulates refrigerant through the evaporator circuit to absorb heat from the fresh-food compartment
• Helps the system reach and maintain target cooling temperatures
• Commonly replaced when corrosion, leaks, or physical damage reduce cooling efficiency
• Required if symptoms include weak cooling, frost pattern changes, or visible refrigerant leakage

• Disconnect power and follow all safety procedures before servicing
• Inspect surrounding tubing and fittings for damage or corrosion; replace any compromised components
• Use proper leak-testing and vacuum procedures when recharging the system

This inverter motor control board manages variable motor speed to enable smooth, efficient operation of the appliance. Replaces a failed inverter to restore proper motor control and reduce erratic motor behavior. What it does:

• Controls variable-speed motor operation and converts power for the motor drive
• Helps maintain steady motor speed during cycles for consistent performance
• Often replaces a faulty inverter causing motor stalls, error codes, or loss of drive
• Can resolve intermittent operation, humming, or motors that won't start

• Disconnect power before attempting replacement to avoid shock or damage
• Handle the control board by its edges and avoid touching components or connectors
• Verify connector alignment and secure mounting; confirm all wiring matches original
• If you see corrosion or other damaged wiring, inspect and repair harnesses before powering up

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

The Compressor is an OEM part for Bosch refrigerators. This part is responsible for maintaining the desired temperature inside your refrigerator by compressing and circulating refrigerant throughout the cooling system.

A bad compressor can occur due to electrical malfunctions, mechanical failures, or normal wear and tear over time. Signs of a faulty compressor include inadequate cooling, unusual noises coming from the refrigerator, or the refrigerator not turning on at all.

Symptoms of a bad compressor include:

• Inadequate cooling 
• Unusual noises 
• The refrigerator not turning on  

Replace your faulty compressor with this genuine OEM Bosch part to restore your refrigerator. This Bosch part can also be used on Thermador and Gaggenau appliances.
 

This valve controls water flow into the appliance, restoring proper filling and water delivery. Replaces a worn or leaking inlet/fill valve to help stop underfilling, overfilling, or continuous water flow. What it does:

• Opens and closes to allow water into the unit during fill cycles
• Stops water flow when fill level is reached to prevent flooding or overfill
• Commonly used when the appliance won't fill, fills slowly, or runs continuously
• Designed to mate with the appliance's water line and electrical connector

• One valve assembly (1 each)

• Disconnect power and shut off the water supply before replacing the valve
• Handle electrical connections and water fittings carefully; use proper tools and tighten fittings to OEM torque specs
• Inspect inlet hoses and fittings for damage and replace if needed to prevent leaks

This heating element replaces the dryer's main electric heater assembly to restore normal drying performance and consistent drum temperatures. Designed to match the OEM form and fit for safe, reliable heat generation. What it does:

• Heats incoming air so clothes dry properly and cycle times are consistent.
• Replaces a failed or open heater that can cause no-heat or reduced-heat symptoms.
• Helps correct long dry times and loads that remain damp after a full cycle.
• Stops erratic temperature behavior when the original element is burnt, broken, or has an open circuit.

• One heating element assembly

• Disconnect power at the breaker or unplug the dryer before starting any work.
• Allow all components to cool and follow OEM service instructions; wear gloves to protect against sharp edges.
• Inspect related parts (thermal fuse, thermostat, wiring) for damage and replace as needed per OEM guidance.

The Thermistor is an OEM part for Bosch refrigerators. It monitors the temperature inside the refrigerator and communicating it to the control board. The thermistor plays a vital role in maintaining the optimal cooling performance and ensuring food is stored at a safe and proper temperature.

Causes of a bad thermistor can include failure due to age, exposure to excessive heat or cold, or damage from impact or moisture.

Symptoms of a bad thermistor include:

• Inconsistent or fluctuating interior refrigerator temperature
• The refrigerator failing to cool properly
• Error codes or fault messages showing on the control panel

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

This air baffle assembly controls airflow between refrigerator compartments to help maintain even temperatures and proper circulation. Replaces a worn or broken damper to reduce uneven cooling and airflow issues. What it does:

• Directs cold air from the evaporator into the fresh food and freezer sections
• Helps maintain consistent temperatures by opening and closing airflow paths
• Commonly replaces units that are cracked, stuck, or no longer sealing properly
• Can reduce symptoms like uneven cooling, warm spots, or excessive frost buildup near the evaporator

• One air baffle assembly

• Disconnect power before servicing to avoid shock or injury
• Remove interior panels or shelving as needed for access; handle the baffle carefully to avoid damage
• Align tabs and mounting points; ensure the damper moves freely after installation
• Follow the refrigerator's service manual or manufacturer instructions for model-specific removal and torque details

This roller set replaces worn or broken rack wheels so your dishwasher rack slides smoothly and stays aligned. It restores quiet, stable rack movement and prevents the rack from catching or tipping when pulled. What it does:

• Replaces damaged or missing rack wheels to restore smooth sliding action
• Helps keep the rack aligned and prevents it from sticking or catching
• Reduces noise and wobble when opening or closing the rack
• Works with the rack's axle to support proper rolling motion

• Disconnect power and turn off water supply before starting repairs
• Remove the dish rack to access and replace the rollers; keep track of axle and clips
• Use basic hand tools; inspect the axle and track for debris or damage before reassembly
