Intro: A smoking oven is usually caused by burnt food or grease, not a fault.
1. Check for spills
Burnt food on the bottom smokes quickly.
2. Clean the oven
Grease on the sides burns at high heat.
3. Remove old foil
Foil can trap heat and burn.
4. Avoid using too much oil
Excess oil splatters and smokes.
5. When to get help
If smoke smells electrical or chemical.
Summary: Most smoking ovens just need a clean or spill removal.
