Share your love

Have you ever noticed smoke coming from your oven when you turn it on? It can be surprising and a bit worrying. But don’t panic! This happens to many people, and there are reasons why.

Your oven might smoke while heating because of food spills or grease inside getting hot. Sometimes, leftover food or oils can burn and make smoke. Also, if something plastic or paper accidentally got inside, it could smoke.

Make sure your oven is clean and nothing is inside before using it. If it keeps smoking a lot or smells bad, it’s best to stop using it and get it checked by someone who fixes appliances.

In this article, we’ll explore why your oven might smoke when you’re preheating it. Understanding these reasons can help you keep your kitchen safe and your cooking experiences enjoyable.

Why is My Oven Smoking While Preheating

Oven Smoking While Preheating: Troubleshooting Guide

If your oven is smoking when you’re warming it up, it might happen because of a few things.

Food Residue

Sometimes, when food or grease falls inside your oven, it can start to smoke when the oven gets hot. This happens because the leftover food bits or grease heat up and make smoke.


If there are any food drips on the part of the oven that gets really hot (like the heating element or the bottom), they can start to smoke too. As they get heated, they turn into smoke.

Excess Oil or Grease

Oil or grease that has built up inside your oven over time can also cause smoking. When the oven starts to heat up, this built-up oil or grease can heat up too much and create smoke.

How to Fix Oven Smoking While Preheating

If your oven is smoking when you’re trying to heat it up, here are some simple steps you can follow to fix the problem:

1. Turn Off the Oven

When you notice smoke coming from your oven, the first thing to do is turn it off immediately. This stops the oven from getting hotter and making more smoke.

2. Let It Cool down

After turning off the oven, give it some time to cool down. You don't want to touch anything inside while it’s still very hot. It’s safer to wait until it’s cool enough to work with.

3. Check for Food Residue

Once the oven is cool, open the door and look inside. Check if there are any bits of food or grease that might be causing the smoke. These can sometimes spill over or get stuck on the walls or the bottom of the oven.

4. Clean inside the Oven

If you see any food residue or grease, it’s time to clean it out. Here's how you can do it:

  • Remove Racks: Take out the racks and trays inside the oven. This makes it easier to reach all the spots that need cleaning.
  • Use a Damp Cloth: Wipe down the interior of the oven with a damp cloth or sponge. Make sure to get into the corners and edges where residue might hide.
  • Use Oven Cleaner (if needed): If there are stubborn stains or grease buildup, you can use an oven cleaner. Follow the instructions on the cleaner carefully and make sure the area is well-ventilated.
  • Clean Racks Separately: Wash the racks separately with warm, soapy water. Let them dry completely before putting them back into the oven.

5. Check the Heating Element

Carefully inspect the heating element at the bottom of the oven. Sometimes, food drips or spills onto this element and burns, causing smoke. If you see any residue, clean it gently with a cloth or sponge.

6. Remove Excess Oil or Grease

If there’s built-up oil or grease in the oven, especially on the walls or ceiling, clean it off. Use a suitable cleaner or a mixture of baking soda and water to scrub away the grease. Rinse with clean water and dry thoroughly.

7. Ventilate the Kitchen

While cleaning and after you've finished, open windows or turn on the kitchen ventilation fan. This helps to clear out any remaining smoke or odors from the oven.

8. Prevent Future Issues

To avoid your oven smoking again in the future, follow these tips:

  • Clean Regularly: Make it a habit to clean your oven every few months, especially if you use it often. This prevents food and grease from building up and causing smoke.
  • Use Oven Liners or Foil: Place oven liners or aluminum foil on the bottom rack to catch spills and drips. This makes it easier to clean up and prevents residues from burning and smoking.
  • Avoid Overfilling: Try not to overfill pans or baking dishes, as spills are more likely to happen and cause smoke.
  • Inspect Before Use: Before preheating the oven, quickly inspect it to ensure there are no leftover food bits or spills from previous use.

By following these steps and tips, you can effectively fix and prevent your oven from smoking while preheating. If the smoking persists despite cleaning, it may be a sign of a more serious issue, and it would be wise to consult the oven’s manual or contact a professional for help.
