Oven smells like burning food even when empty

Symptoms

• Smell appears as soon as the oven heats up
• Visible dark residue or spatter inside the oven
• Smell may include light smoke
• No food currently in the oven

Likely causes

• CommonGrease and food residue baked onto oven surfacesPast spills and splatters burn off every time the oven heats, creating smoke and smell.
• CommonDebris resting directly on the heating element or burner areaFood that fell onto a hot component burns repeatedly.
• PossibleFoil or a liner blocking airflow and burningImproperly placed foil can scorch and smell.
• PossibleSelf-clean cycle overdueA long-overdue clean means more accumulated residue.

What to do

1. Let the oven cool completely, then remove racks and any foil or liners.
2. Visually inspect the oven floor, walls, and door glass for baked-on residue or debris.
3. Wipe out loose debris and clean the interior with an oven-safe cleaner or a baking soda paste, avoiding the heating elements directly on electric-ignition parts.
4. Check under and around the broiler or bake burner area for debris that fell in, being careful not to disturb the igniter.
5. Run the self-clean cycle if your oven has one and it hasn't been used in a long time, following the manual's guidance and ventilating the kitchen.
6. Avoid using foil directly on the oven floor going forward, since it can trap heat and debris.

Tools and parts

• Baking soda
• Non-abrasive scrub pad

When to call a pro

This is a cleaning issue you can usually resolve yourself; a technician is only needed if a smell persists after a thorough clean.
