Oven does not heat evenly; food is burnt at the back and undercooked at the front in convection mode.

Safety: Allow the oven to cool and disconnect power before removing internal panels.

• 1. Clean the cavity: Remove racks and thoroughly clean the rear wall, fan cover, and side walls to remove grease that can disrupt airflow.
• 2. Inspect fan cover: Remove the rear fan cover inside the cavity. Clean any baked-on debris blocking the air slots.
• 3. Check fan blade condition: Inspect the convection fan blades for warping or heavy grease build-up. Clean carefully; replace the fan blade if bent.
• 4. Test fan speed: With the oven reassembled and powered, run a convection mode and listen for smooth, strong airflow. A weak or noisy fan suggests a failing motor that should be replaced.
• 5. Rack positioning: Use the rack positions recommended in the Panasonic manual for even baking and avoid blocking airflow with oversized trays.
