Parts for Bosch HBN452AUC: Upper Cavity Parts

The Heater Element Range is an OEM component specifically designed for Bosch cooktops and ranges. It plays an integral role in the heating system by generating targeted radiant heat for cooking and baking. The heater element distributes heat efficiently and reliably across the cooking surface.

Causes of a failed heater element can include mineral deposits building up over time, and reducing heat transfer. Physical damage, excessive bending, or accidental impact may also compromise element integrity.

Symptoms of a bad heater element include:

• Inconsistent or weak heat output from the burner/cooktop zone  
• Extended cooking times to reach desired temperatures
• Buzzing, clicking, or odd sounds coming from below the surface
• Burner or entire cooktop failing to heat at all

Replacing with this genuine Bosch part restores optimized heat performance. It is also compatible with Thermador, Dacor, and some Viking cooking appliance models. 
 

This cavity partition is the internal oven divider that maintains proper separation and airflow inside the cooking cavity for safe, consistent operation. It restores the oven's internal structure after damage or during repairs. What it does:

• Reestablishes the internal divider that separates oven compartments and supports correct airflow distribution
• Helps maintain even cooking by preserving the oven's designed cavity geometry
• Addresses symptoms like loose or missing interior panels, rattling inside the oven, or gaps in the oven wall
• Prevents contact between components that should remain separated, reducing risk of internal damage

• One cavity partition (single-piece) as shown

• Refer to the oven's service manual for correct placement and fastening sequence
• Disconnect power and allow the appliance to cool completely before servicing
• Handle edges with care; wear gloves to avoid cuts and protect finished surfaces
• If fasteners or clips are damaged or missing, replace them; part ships without additional hardware
