Oven produces excessive smoke during normal baking (not self-clean).

Safety first: If smoke is heavy, turn off the oven and open windows. Avoid opening the door fully if there is active flame.

• Inspect interior: Once cool, remove racks and inspect the bottom and sides for heavy grease or food buildup. Clean with a non-abrasive oven cleaner approved for Whirlpool ovens.
• Avoid foil on bottom: Do not line the oven bottom with foil, as it can trap spills and cause smoking. Use a proper oven liner if allowed by the manual.
• Burn-off new oven: For a new Whirlpool oven, run a 400–450°F bake cycle for 30–60 minutes empty to burn off manufacturing residues, following the user manual.
• Check temperature: Verify the oven is not overheating by comparing with an oven thermometer. If significantly high, see temperature calibration procedures.
