Parts for Bosch HBN3520UC/01: Pcb Assembly Parts

Fix error codes, temperature control issues, or a non-responsive oven. This electronic control board manages timing and coordinates all oven functions.

Fix error codes, temperature control issues, or a non-responsive oven. This electronic control board manages timing and coordinates all oven functions.

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.
 

Oven not heating evenly or taking too long to preheat? A faulty blower wheel disrupts air circulation. This fan wheel restores proper airflow.

Replace your wall oven door latch if the door won't stay closed, the oven won't start, or cycles are interrupted. Restores proper door closure and locking.

Factory fixing kit with mounting hardware to secure panels, brackets, or trim on your wall oven. Replaces worn, missing, or damaged fasteners for alignment.

Secures wall oven panels and components in place. Replace this mounting bracket when the original is broken, bent, or missing, causing loose panels or misalignment.

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

Wall oven not powering on or display blank? This cable harness restores electrical connections. Moderate DIY repair taking 30-45 minutes.

This cable harness connects and routes electrical signals between appliance controls and components to restore reliable communication and power paths. It replaces a damaged or worn wiring assembly to help resolve intermittent or failed component operation. What it does:

• Transfers power and control signals between the control board and components (motors, valves, sensors).
• Restores lost connections caused by frayed, broken, or burned wires.
• Helps address symptoms like intermittent operation, error codes related to communication, or non-responsive controls.
• Provides factory-style connectors and routing to maintain proper electrical and mechanical fit.

• Cable harness

• Turn off power to the appliance at the breaker or unplug before starting; verify power is off.
• Match connector shapes and wire colors to the original harness before disconnecting to ensure correct reassembly.
• Handle connectors by the housings; do not pull on individual wires.
• If pins or connector housings are damaged, replace the entire harness—do not attempt to splice if a secure OEM connector is required.

Wall oven not heating or display not working? This cable harness connects electrical components. Common fix for power issues. DIY repair in 30-45 minutes.

Wall oven not heating or displaying errors? A faulty cable harness often causes electrical failures. This internal wiring assembly typically requires 1-2 hours to replace with moderate skill.
