Parts for Bosch HBN3550UC/10: Oven Upper Parts

Replacement interior lamp that restores lighting inside your appliance so you can see contents and monitor cooking without opening the door. Simple, direct-fit replacement for compatible Bosch appliances. What it does:

• Provides interior illumination so you can safely check food and cooking progress.
• Replaces a burned-out, dim, or flickering lamp that causes the interior light to fail.
• Fits the existing lamp socket and reconnects to the appliance's original wiring; restores normal lighting without modifying the appliance.

• Always disconnect power or unplug the appliance before replacing the lamp to avoid shock.
• Allow the old lamp to cool completely; handle the new lamp with gloves or a clean cloth to avoid contaminating the glass.
• Seat the lamp into the socket without forcing; restore power and test operation.

This convection fan motor drives the oven's internal fan to circulate hot air during convection cooking. Replacing a weak or seized motor restores proper airflow for more even heating, reliable temperatures, and consistent baking and roasting results.

• Powers the convection fan to move heated air across racks for even cooking
• Helps maintain stable cavity temperature and quicker recovery after door openings
• Common symptoms of a failing motor: fan won't turn, intermittent start/stop, loud squeal or grinding, uneven baking/roasting, or a fan-related error

• Disconnect power at the breaker before servicing
• Access from the rear of the unit or through the oven cavity (model dependent); remove the appropriate panel to reach the motor
• Note wire positions and motor orientation; transfer any brackets, grommets, or screws from the original if needed
• Ensure the fan blade spins freely and is properly seated before reassembly

This sealing plug closes an unused port or opening to prevent leaks and keep internal components protected. It restores a watertight seal and helps prevent debris or moisture from entering appliance cavities. What it does:

• Seals an open port or service access to stop water leaks and moisture intrusion
• Helps keep debris and contaminants out of pumps, valves or internal cavities
• Restores proper sealing after maintenance or component replacement
• Can reduce risk of water damage or corrosion when installed correctly

• Disconnect power and water supply before accessing the part
• Inspect any O-rings or sealing surfaces; replace damaged seals
• Hand-tighten or press into place per manufacturer guidance; avoid over-tightening

This replacement door seal is the appliance gasket that restores a tight, reliable seal where the door meets the cabinet. Replacing a worn or damaged seal helps stop leaks, reduce energy loss, and improve performance. What it does:

• Creates a weather-tight barrier at the door to prevent water or air from escaping
• Helps maintain proper internal temperature and energy efficiency
• Reduces drafts, moisture build-up, and related odors
• Restores normal operation when a torn, compressed, or hardened gasket causes leaks

• One door seal/gasket

• Disconnect power to the appliance before starting any work
• Remove the old gasket carefully; some models use clips, channels, or adhesive—retain fasteners as needed
• Seat the new seal evenly into the channel and compress gently to form a continuous seal
• After installation, run a brief test (no operation if unsafe) and inspect for uniform contact around the door

The Sensor is an OEM replacement part for Bosch ranges. It monitors conditions inside the oven compartment such as temperature and diagnosing faults. 

Symptoms of a bad sensor include:

• The oven not heating or cooking unevenly
• Inaccurate temperature readings displayed  
• Erratic or unpredictable ignition/operation  
• Error codes appearing related to sensor faults

Causes of failure can be normal wear over time from high heat exposure, accidental damage compromising sensor integrity, or intrusion of liquids or debris confusing readings.

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

A fixing kit that provides the mounting hardware needed to secure appliance panels and components for stable operation. Use this kit to replace missing or damaged fasteners so parts stay properly aligned and reduce vibration. What it does:

• Supplies replacement mounting hardware to secure panels, brackets, and trim
• Restores proper fit to reduce movement, rattling, or misalignment
• Helps maintain normal operation by keeping components fixed in place
• Useful when original fasteners are lost, corroded, or broken

• Disconnect power and water before starting any repair
• Use basic hand tools; follow the appliance service manual for correct placement
• Tighten fasteners snugly but avoid over-torquing to prevent damage

This service access cover protects internal components and wiring while keeping the appliance's exterior neat. It restores a clean appearance and helps prevent accidental contact with internal parts during normal use. What it does:

• Protects internal components, connectors and wiring from dust and debris
• Helps reduce risk of accidental contact with electrical parts
• Restores the appliance's finished look after repairs or maintenance
• Useful when replacing or servicing nearby components that require the cover removed

• Disconnect power (unplug or switch off circuit breaker) before starting any work
• Remove and reinstall using the factory mounting clips or screws; avoid forcing the cover to prevent breakage
• Handle plastic tabs gently—inspect tabs and mounting points for damage before final install

Heater-Bottom replaces the dishwasher's lower heating element, restoring water heating and improving wash and drying performance. It heats wash water for effective cleaning and helps reduce moisture left in the tub after a cycle. What it does:

• Warms wash and rinse water so detergent dissolves and soils are removed more effectively — symptom: poor cleaning performance.
• Raises final rinse temperature to aid drying — symptom: dishes stay wet after cycle.
• Replaces a failed or open bottom heating element — symptom: no heat or heater-related error/alerts.
• Restores normal cycle operation when temperature-dependent functions are affected.

• Disconnect power to the appliance before beginning any repair to avoid electric shock.
• Route wires exactly as the original; ensure all connector terminals are fully seated.
• Inspect wiring and insulation for damage and replace any compromised components to prevent shorts.
• Test the element for continuity with a multimeter before and after installation to ensure proper operation.

This support mounting bracket secures internal components to the appliance frame, restoring proper alignment and stable operation. It replaces a worn, broken, or loose support to help reduce rattling and prevent component sag. What it does:

• Provides a secure mounting point for internal parts and assemblies
• Re-establishes correct alignment when a bracket is bent or broken
• Helps reduce vibration and rattling caused by loose or damaged supports
• Commonly replaced when a component shifts, rubs, or no longer sits flush

• Disconnect power and water before starting any repair.
• Basic hand tools are typically required; follow OEM service instructions for disassembly/reassembly.
• Inspect adjacent fasteners and clips; replace any that are damaged to ensure a secure fit.

The Bake Element is an OEM part for Bosch ranges. This bake element replaces the standard heating coil located at the bottom of the oven cavity and provides reliable, even heating for baking, roasting and more.

Causes of a bad bake element can include normal wear and tear over time, becoming clogged with burnt-on residue, or failure of internal wires or heating coils.

Symptoms of a bad bake element include:

• Fluctuating oven temperatures
• Uneven or inefficient cooking/baking
• The oven not heating at all or only heating to a low temperature

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