Oven interior surfaces remain dirty even after running a full pyrolytic self-clean cycle.

Safety first: Allow the oven to cool completely after self-clean before wiping or inspecting.

• Check door seal: Inspect the gasket for gaps that could allow heat to escape. Replace if worn.
• Verify heating: If the cavity did not reach very high temperatures (no visible ash), test the bake and grill elements and temperature sensor for proper operation.
• Run another cycle: For very heavy soil, a second self-clean cycle may be necessary. Remove large food residues manually first.
• Manual cleaning: Use a non-abrasive cleaner for any remaining spots that self-clean cannot remove.
