User Suggested Solutions

Remove the oven's inner panels to access the insulation. Carefully cut away the damaged insulation and replace it with new insulation material designed for ovens. Seal any seams with high-temperature adhesive. Reassemble the oven and test for heat retention.
Clean the affected area thoroughly to remove any residual oil. If the insulation is not severely damaged, allow it to dry completely and apply a protective coating to prevent further damage. Monitor the area for any signs of recurring issues.
If the insulation damage is extensive or if the oven is not functioning properly after DIY repairs, consider replacing the entire oven unit or contacting a professional for a thorough inspection and repair.
