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
What's included:
  • One cavity partition (single-piece) as shown
Install notes:
  • 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
