  • Turn on the oven. Set it to its highest temperature setting or as suggested in the manual (typically around 450°F or 232°C).
  • Run the oven empty for about 30 minutes to an hour. This process burns off manufacturing residues and protective coatings that can produce odors.
  • It’s normal to notice a peculiar smell or even slight smoke during this phase.

Step 6: Cool Down: After the initial burn-off, turn off the oven and allow it to cool.

Step 7: Clean the Interior: While often not necessary, you can wipe down the interior with a damp cloth to ensure it’s clean and ready for cooking.

Step 8: Test with a Simple Recipe: Before preparing a grand feast, you might want to start with a simpler dish to familiarize yourself with the oven’s cooking times and temperatures.

Step 9: Oven Thermometer: Consider using an oven thermometer during the first few uses. This device will help you confirm if your oven’s temperature settings are accurate.

Step 10: Calibrate if Necessary: If you notice temperature discrepancies, consult your oven’s manual for calibration instructions.

What Causes The Smell In the New Oven?

The smell in a new oven is usually not a cause for concern and is quite common. Here’s what causes it:

  1. Manufacturing Residues: During the manufacturing process, oils and other chemicals can be left behind on metal and other parts of the oven. When the oven is heated for the first time, these residues can produce a distinct odor.
  2. Protective Coatings: Some ovens come with a protective coating to prevent scratches and damage during shipping. This coating, when subjected to high temperatures, can emit a smell as it burns off.
  3. Insulation: The insulation materials used in ovens can also give off a smell when they’re heated for the first few times. This is typical and usually dissipates after a few uses.
  4. Adhesives: The adhesives used to bond certain parts of the oven, especially the gaskets, can release odors when they’re first heated.
  5. New Materials: Just like other new products, the materials used to construct the oven—like metals, paints, and finishes—can produce an odor when first exposed to heat. It’s similar to the “new car smell” that comes from the combination of materials used in the car’s interior.

How To Get Rid Of Smell Form New Oven?

The smell from a new oven is often due to manufacturing residues or protective coatings that are applied to the oven’s components. Here’s how you can effectively get rid of the smell:

Initial Burn-off: Set the oven to its highest temperature, typically around 450°F (232°C) or as recommended by the manufacturer. Let it run for 30 minutes to an hour. This should burn off most manufacturing residues.

Ventilation: Ensure your kitchen is well-ventilated during the burn-off process. Open windows and use exhaust fans to dissipate the smell faster.

Cleaning: Once the oven cools after the burn-off, clean the interior with a mixture of equal parts water and white vinegar or with a mild soapy solution. This helps in removing any residual odors. Rinse with plain water and then dry the interior with a soft cloth.

Baking Soda: Another method to neutralize odors is by spreading a thin layer of baking soda on a baking sheet and then baking it at a low temperature for an hour or so. Baking soda is known to absorb odors.

Lemon or Vanilla: Cut a lemon into slices and place them on a baking sheet or in a heatproof dish. Bake at a low temperature for an hour. Alternatively, you can also add a few drops of vanilla extract to a bowl of water and heat it in the oven. Both lemon and vanilla can help neutralize and mask unpleasant odors.

Multiple Sessions: If the smell persists after the first burn-off, you might need to repeat the process once or twice more.

Check the Manual: Always refer to the manufacturer’s guidelines. Some ovens may have specific instructions or recommendations for eliminating initial odors.

By following these methods and ensuring your oven is clean and free from residues, you’ll be well on your way to a smell-free cooking experience. If the odor persists beyond these measures, it might be a good idea to contact the manufacturer or a technician to ensure there isn’t a more significant issue with your appliance.
