Why Is My Oven Smoking? 6 Common Problems and Solutions

Whether you’re baking cookies or whipping up some comfort food, the smell of an oven smoking can quickly turn a heartfelt moment into a major headache. Fortunately, a little sleuthing can help you narrow down why your oven is smoking and fix the problem pronto. Here are six reasons why an oven might smoke—and what you can do about it.

1. Factory Coating

The first few times you use a new oven can result in a smoky atmosphere and a strange odor to match. This can come from a failure to fully remove the packaging material, or it could be from the bonding agents as a normal part of the manufacturing process.

How to Fix It

If the smell of your new oven resembles burnt plastic, wait for the unit to cool off before inspecting the inside for signs of leftover packaging materials and discarding them. 

For oily or synthetic smells, you’ll need to wait for the new parts, binding agents, and manufacturing residue to burn off or get accustomed to use. Consider ventilating your kitchen and cranking the fans to air it out during the first few uses, and run the cycles on empty to keep odors from leaching into your food. 

2. It’s Dirty

Don’t remember the last time you gave your oven a deep clean? There’s a high probability that your oven smoking comes from debris and grease buildup. 

How to Fix It

Deep-cleaning your oven every three months can help prevent burnt food and grease buildup from burning when you use it. You can use your oven’s self-cleaning setting, according to the manufacturer, or a store-bought cleaning product. Manually cleaning an oven using a DIY cleaner may work even better. Use a wet cloth soaked in vinegar and baking soda to wipe your oven down.  

3. Residual Cleaning Solution

While it makes sense to use a store-bought cleaning solution made just for ovens, these solutions can leave soap residue that ends up burning and causing your oven to smoke. 

How to Fix It

Double-check the instruction manual for your oven to ensure you’re using the correct products. Then, when your oven is cool, wipe it down after using the oven cleaner using a damp cloth to remove product buildup. 

4. Food Dripping

Even if you’ve diligently cleaned your oven, food and grease can trickle out of what you’re making and burn. When this happens, it’ll usually drop to the bottom of your oven and start to smoke. 

How to Fix It

You can prevent food from dripping below the oven sheet or pan by prepping ahead of time. Tin foil, oven sheets, and even a baking sheet can be placed below the food you’re cooking to catch pesky drips before they land on the bottom of your oven. Check your user manual first, though, as some materials work better than others.

5. Burnt Food

From forgetting to set a timer to incorrectly positioning your food, one wrong move can cause your meal to get scorched and smoke. This user error is relatively easy to fix, fortunately. 

How to Fix It

Avoid placing dishes, pans, or baking sheets too close to the heating element, as this is the hottest part of the oven. Remember to follow the instructions and take preventative measures—like covering susceptible areas of the meal with aluminum foil—to keep the food from burning. 

6. Broken Heating Element

Sometimes, an oven that smokes indicates a broken heating element. If your oven is old, the heating element can wear out and fail to activate properly during the baking or broiling process. 

When your heating element is the problem, you might hear a buzzing sound in your oven as it tries to operate. Your food might come out undercooked, and there may be signs of burning or bulging when you visually inspect your oven. Gas ovens may have too much pressure in the heating element, which can also cause it to smoke. 

How to Fix It

Repairing a broken heating element is not a DIY task. To fix this problem, contact a local oven repair company to handle the job. Oven repair costs fall between $130 and $310 on average.

Signs of a Smoking Oven

If you’re unsure if your oven is the culprit behind the smoke or odor in your house, there are several telltale signs to tip you off and help you solve the issue faster. 

• Visible burn marks: While inspecting your oven, look for scorched sections or blackened food or grease particles.

• Buzzing sound: If you hear a buzzing sound accompanied by a burning smell, there’s a good chance your oven is acting up.

• Burning smell: A burning odor while operating your oven is an indication of a smoking oven. 

• Smoke in the air: Keep an ear out for a smoke detector that keeps going off when you use your oven or open the door.

When to Call a Pro

While some simple causes are easy to fix on your own, like cleaning your oven, cooking your food for the correct amount of time, removing the cleaning solution, and preventing food from dripping to the bottom of your oven, other issues are more complex. If you’ve tried all the easy solutions and suspect a faulty heating element or other mechanical problem, you should hire an oven repair pro near you to inspect your oven and get to the root cause. 

How to Prevent an Oven from Smoking

Preventing an oven from smoking in the first place can save you a lot of stress—and maybe even save you money on repair costs. Here are a few tips on how to prevent a smoking oven:

• Regularly clean and maintain your oven.

• Follow the instruction manual to correctly clean your oven.

• Never leave your oven unattended while in use. 

• Avoid overcooking or overbaking your oven.

• Replace old, faulty ovens.

• Ventilate the area when using a new oven for the first couple of times.
