Parts for Bosch HBN5660UC/01: Pcb Parts

This control module is the appliance's electronic brain. It interprets inputs from the user interface and sensors, then switches power to the appropriate components so cycles run correctly and reliably.

• Coordinates cycle timing and core functions
• Receives signals from switches/sensors and drives relays to power loads
• Common symptoms of a failed board: unresponsive controls or won't start, cycles that won't advance/finish, intermittent operation, random lights/beeps, or error codes
• May show visible damage such as burnt spots or blown components

• Disconnect power at the breaker or unplug the unit before servicing
• Use ESD protection and handle the board by the edges
• Photograph wiring and transfer connectors one at a time to the matching terminals
• Follow model-specific service steps; some units require initialization/diagnostics after replacement

The Relay is an OEM component specifically designed for select Bosch built-in ovens. As a basic electronic switch, it receives signals from the control unit to energize heating elements. 

Durable plastic encapsulation protects delicate components from accidental spills. Precise switching facilitates customized baking and broiling temperatures within close tolerances.

Causes signaling relay failure related to prolonged thermal stresses from consistent oven use. Impacts of electric abnormalities could also cause malfunctions over time.

Symptoms requiring replacement include:  

• Inability to power top or bottom heating elements during cycles
• Erratic temperature fluctuations beyond adjustment capabilities
• Buzzing or loud clicking noises emitting from the relay housing

This OEM Bosch replacement part is also compatible with Thermador, Gaggenau, and select Kenmore built-in ovens employing identical temperature modulation methods. Reinstallation ensures continued customizable and safe cycle performance.
 

This fan blower wheel circulates air inside the appliance to help maintain even temperatures and proper cooling. Replacing a worn or broken fan restores airflow and helps the appliance reach set temperatures consistently. What it does:

• Moves air through the evaporator/condenser area to support cooling and defrost cycles
• Helps prevent hot or cold spots by circulating conditioned air
• Commonly related to reduced cooling, noisy operation, or no airflow from the vents
• Can be a root cause of frost buildup or temperature fluctuations when failed

• Disconnect power before starting any repair to avoid electrical shock
• Access may require removing interior panels or the evaporator/condenser cover
• Inspect the mounting and motor for wear; replace the fan only if it matches the OEM shape and fit

This door latch secures the appliance door and helps enable normal operation by keeping the door closed and latched during cycles. Replacing a worn or broken latch restores proper door engagement and reliable start/lock behavior. What it does:

• Secures the door closed so the appliance can run and complete cycles
• Engages with the strike to maintain a tight, consistent seal during operation
• Helps the control detect a closed/locked door and permit cycle start
• Commonly replaced when the door won't stay closed, won't lock, or the unit won't start

• One replacement door latch

• Disconnect power and water before beginning any repair
• Access may require removing the inner door panel or front trim—keep fasteners organized
• Verify alignment of the latch and strike before reassembly to ensure proper engagement
• If the latch has electrical connectors, reconnect securely and avoid pinching wires

This factory fixing kit provides the mounting hardware needed to secure the applicable component or panel on your appliance. Replacing worn or missing fasteners restores proper alignment and a solid, rattle-free installation.

• Secures panels, brackets, or trim to the appliance chassis or door
• Helps prevent shifting, vibration, and rattling during operation
• Restores correct alignment and fit when hardware is missing or stripped
• Useful during initial installation or when re-installing serviced parts

• Disconnect electrical power; if your appliance is plumbed, shut off water before servicing
• Follow your model's installation/service instructions for exact hardware locations and orientation
• Tighten hardware evenly; do not overtighten to avoid damaging plastic or sheet metal
• Verify alignment and smooth operation before restoring power and/or water

This mounting bracket secures appliance panels or components in place to restore proper fit and stable operation. A simple replacement when a broken or bent bracket causes rattling, misalignment, or loose panels. What it does

• Provides structural support to hold panels, trim, or assemblies in position
• Prevents rattling and vibration from a loose or damaged bracket
• Restores proper alignment of the attached component for normal operation
• Can fail from bending, cracking, or fastener loss, leading to gaps or movement

• One mounting bracket

• Disconnect power and shut off water before starting any repair
• Use appropriate tools to remove fasteners; keep track of mounting screws or clips
• Inspect surrounding parts and fasteners for damage; replace any stripped hardware
• Handle sharp edges carefully and test fit before reassembly

This cable harness connects key electrical components to restore power and signal flow in the appliance. It replaces a damaged or faulty wiring harness to help return controls and components to normal operation. What it does:

• Carries power and control signals between the control board and components
• Replaces frayed, burned, or broken wires that cause intermittent or no operation
• Common symptoms it can address: appliance won't start, controls unresponsive, intermittent cycles, or error codes related to open/shorted circuits
• Helps ensure secure connector mating and correct signal routing when installed properly

• Disconnect power at the breaker or unplug the appliance before starting any repairs
• Compare the new harness to the old one and follow the appliance wiring diagram for correct routing and connector placement
• Secure connectors fully; avoid sharp bends or pinching the wires during reassembly
