An oven that produces smoke when baking or broiling food might be due for a good cleaning or it may also indicate defective part or the need for a repair.
WARNING! Before attempting to work on any appliance, make sure that all power (electricity) and utilities (water and gas) have been turned off and/or disconnected on the appliance. Read this before you start any repair.
If you have a new oven, it’s recommended that a “burn in” is performed before using it to bake or cook food. The smoke produced from the new oven burn in process can be caused by the protective coating used on new oven, or can even be caused by the insulation surrounding the oven. Once the burn in is completed, your oven should be smoke-free.

Left over food bits and grease can cause an oven to smoke. A good cleaning will solve this issue. Wait till the oven is cool and consult the owner’s manual for any suggestions from the manufacturer on how to clean it.
Using the self-cleaning cycle might also produce smoke as the cycle reaches incredibly high temperatures in order to incinerate food particles and spills. Wait till the cycle is complete and the oven has cooled down before wiping up any remaining ash or residue left over before using your oven again.
In the future, prevent smoking by minimizing spills with these tips
- Do not bake items directly on the oven racks.
- Wipe up any splatters or spills right after the oven cools.
- Make sure that food is not placed too close to the heating source. For electric ovens, maintain a distance of three inches from the heating element and the food.
If using a commercial or homemade cleaner, make sure all of it is thoroughly removed before using the oven again. A popular DIY cleaning recipe often involves making a thick paste out of baking powder and other natural ingredients and coating the oven walls with it. Make sure this cleaning paste is thoroughly removed before cooking with the oven again.
Defective Heating Parts
An electric oven heating element that buzzes or smokes might mean it’s on its way out. Luckily, this is a very easy repair to do.
For gas ovens, an incorrect conversion from natural gas to liquid propane can cause higher flames from the gas burner in the oven. A gas pressure that is too high can lead to taller and hotter flames from the burner which can cause a dangerous fire and should be fixed immediately.
