Bosch Refrigerator B21CT80SNS Parts

This cable harness is the main wiring connector that links control electronics to appliance components, restoring reliable electrical connections and signals. It's used where damaged or corroded wiring causes intermittent operation or control errors. What it does:

• Routes power and signal connections between the control board and components (motors, sensors, valves).
• Replaces frayed, burnt, or loose wiring that can cause intermittent power, failures to start, or error codes.
• Restores secure connector fit and correct wiring continuity for normal appliance operation.
• Helps eliminate issues caused by melted insulation, pin corrosion, or broken connector clips.

• One complete cable harness assembly as shown.

• Disconnect power (unplug or switch off breaker) before starting work to avoid shock or damage.
• Note connector locations and wire routing before removal; take photos if needed.
• Avoid pulling on wires—release locking tabs and pull on the connector bodies.
• Inspect mating connectors and terminals for damage; replace if corroded or loose.

The Fan Cover is an OEM part for Bosch refrigerators. This part protects the fan blades while allowing air to circulate freely within the refrigerator. This part helps to maintain the correct airflow, which is crucial for the refrigerator’s cooling efficiency, ensuring that the temperature is evenly distributed throughout the unit.

Causes of a bad Fan Cover can include physical damage such as cracks or breaks, which may result from accidental impacts during cleaning or maintenance.

Symptoms of a bad Fan Cover include:

• Noticeable increase in operational noise.
• Reduced cooling efficiency or uneven temperatures within the refrigerator.
• Ice buildup or frost in areas that are typically frost-free.

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