If your new electric oven smells, there could be a few reasons. A burning smell is common in new ovens and is usually caused by a protective coating of oil or tape used in the manufacturing process, or packaging materials burning off. This smell should dissipate after the first few uses. If the smell persists, it could be due to food or grease spills, a faulty control panel, or electrical issues. It is recommended to run an empty bake cycle at 350 degrees for 30 minutes to an hour to eliminate the odor and ensure all packaging materials are removed before use. If the smell continues or is accompanied by smoke, it may indicate an electrical problem or a malfunctioning control panel, in which case professional repair is advised.
| Characteristics | Values |
|---|---|
| Reason for the smell | The insulation around the oven cavity is exposed to extreme heat for the first time, causing a chemical smell. |
| Other reasons | Burning plastic, gas, food drippings, faulty wiring, malfunctioning heating element, or a protective coating of oil used during manufacturing. |
| Solution | "Burn-in" the oven before cooking. Remove all packaging, zip ties, and twist ties. Wipe down the racks and oven interior with warm soapy water, then run an empty bake cycle at 350°F for 30 minutes to an hour. |

What You'll Learn

Burning plastic smell
If your new electric oven smells like burning plastic, it is most likely due to the protective coatings, insulation materials, or manufacturing residues inside the oven. These materials are used during the manufacturing process to protect the oven during shipping and handling. When you use a new oven for the first few times, these materials burn off, causing a burning plastic smell.
To resolve this issue, you can try running the oven empty at a high temperature (about 400–550°F or 200–288°C) for 30 minutes to an hour. This process is often referred to as a burn-in or burn-off cycle, and it helps to reduce chemical residues left over from the manufacturing process. Make sure to remove any packaging materials, including zip ties, and thoroughly clean the inside of the oven, including the racks, with warm soapy water before running the burn-in cycle.
If the smell persists after performing the burn-in cycle a few times, there may be an electrical issue. Burning or melting wires can produce a burning plastic smell. If you notice any buzzing, popping, or crackling sounds coming from the oven, there may be an issue with the wiring. In this case, it is recommended to unplug the oven and consult a qualified technician to inspect and repair any electrical issues.
Additionally, if you cannot find any signs of melting plastic or wiring issues, the burning plastic smell could indicate that the main control board is overheating due to a failing relay. In this case, you should monitor the oven's behavior, and if it continues to act unusually, have the main relay board inspected and replaced if necessary.

Insulation and new parts
A burning smell in a new electric oven is often due to the insulation surrounding the oven cavity being exposed to extreme heat for the first time. This is the smell of a bonding agent curing. The insulation emits odours the first few times it is exposed to heat, and this can result in a chemical smell.
If you smell burning plastic, it could be that zip ties used to secure the inserts during transit have not been removed before turning the oven on. In this case, the plastic is melting and burning. It is important to remove all packaging materials before using a new oven, as inhaling burning plastic fumes can be dangerous.
To get rid of the chemical smell, you need to ""burn in" your oven. This involves running the oven at a high temperature for between 30 minutes and an hour. If the smell persists, repeat the process. It is recommended that you do not cook any food before this cycle as the smell (and potentially the taste) can stick to your food. Once the oven is cool, wipe down the inside with a warm, soapy washcloth.
If you smell burning and suspect an electrical problem, such as faulty wiring or a malfunctioning heating element, turn off and unplug your oven, and call for professional repair assistance.

Protective coating
The smell from a new electric oven is likely due to a protective coating of oil that is used during the manufacturing process, as well as the tape used in shipping. This coating is designed to protect the oven's interior from rust and corrosion during transportation and storage. When the oven is turned on for the first time, the coating can burn off, releasing an unpleasant odour.
This protective coating is typically applied to the interior surfaces of the oven, including the walls, racks, and heating elements. It is important to ensure that all packaging materials, such as plastic wrap, cardboard, and foam, are removed from the oven before its first use. These materials can also release toxic fumes when heated, so it is crucial to thoroughly inspect the oven cavity and remove any residual packaging before turning it on.
To eliminate the smell of the protective coating, it is recommended to perform a "burn-in" or "burn-off" cycle. This process involves running the empty oven at a high temperature, typically between 30 minutes to an hour, to allow the coating to burn off completely. During this cycle, it is important to turn on the fan in the ventilation hood and open nearby windows to dissipate the odour and provide adequate ventilation.
After performing the initial burn-in cycle, if the smell persists, it is recommended to repeat the process once or twice more. Once the burning odour has dissipated, allow the oven to cool down, and then wipe down the interior with a soft, damp cloth to remove any residual odours. It is important to note that this process may vary slightly depending on the manufacturer's instructions for your specific oven model.
Overall, the protective coating on a new electric oven is normal and serves an important purpose. By following the recommended burn-in procedure and taking the necessary ventilation precautions, you can safely eliminate the unpleasant odour and prepare your new oven for cooking.

Food debris and grease
If you are experiencing a burning smell in your oven due to food debris or grease, it is recommended to first turn off and unplug the oven for safety. You can then proceed to clean the oven by removing any burnt food or grease with a damp rag or a cleaning solution specifically designed for ovens. It is important to avoid using abrasive cleaners that may damage the oven's interior and never to clean the oven while it is on.
In some cases, the burning smell may be caused by electrical issues, such as faulty wiring or a malfunctioning control panel, which can cause the oven to overheat and burn food. If you suspect an electrical problem, it is best to call for professional repair assistance.
To prevent food debris and grease from causing a burning smell in your oven, it is recommended to regularly clean the oven, including the racks and heating elements. Additionally, always ensure that any food spills or grease splatters are cleaned up immediately to prevent them from burning and causing odours.
If you are experiencing a burning smell in your new electric oven, it is important to first identify the source of the smell. If the smell is due to food debris or grease, follow the cleaning steps mentioned above. However, if the smell persists or is accompanied by other issues, such as overheating, it may indicate an electrical problem that requires professional assistance.

Electrical issues
If your new electric oven smells like burning plastic, it is most likely due to the chemicals and protective coatings in the oven cavity being exposed to heat for the first time. The smell should dissipate after the first few uses. However, if the smell persists, it could indicate electrical issues.
If you suspect a malfunctioning control panel, it may cause the oven to overheat and burn any food inside, resulting in a persistent burning odour. To confirm this, set your oven to a specific temperature and let it preheat. Use a kitchen thermometer to check if the oven's internal temperature matches the set temperature. If there is a significant discrepancy, you may need to replace the control panel or consider upgrading to a new oven.
Another potential electrical issue is faulty wiring. If you detect a strong chemical smell, it could indicate a problem with the oven's insulation or wiring. Again, it is essential to turn off the oven and refrain from attempting any DIY repairs. Contact a professional appliance repair service to address the issue safely and effectively.
To summarise, while a burning smell in a new electric oven is usually harmless, persistent or unusual odours could indicate electrical problems. Always prioritise safety by unplugging the oven and seeking professional assistance for electrical issues.
