The oven is one of the most commonly used appliances in the kitchen and plays a major role in food preparation. However, in some cases, unpleasant odors coming from the oven may disturb users. Such odors negatively affect both the quality of the cooked food and the overall atmosphere of the home. The causes of the odors may include grease buildup, food residues, or technical malfunctions. Sometimes the problem is related to the first-time use of the oven or the incorrect choice of cleaning agents. It is important to correctly identify the cause of these odors and take timely action. Otherwise, using the oven becomes more difficult and health risks may increase. This time, we will explain the main causes of odors coming from the oven, their impact on food and the appliance itself. Useful tips will also be provided to eliminate these problems and prevent them in the future.

Causes of Odors Coming from the Oven

The causes of odors coming from the oven can vary, and distinguishing them correctly plays an important role in solving the problem. Sometimes these odors occur during the first-time use of a new oven, and sometimes they result from the burning of food residues and grease. In other cases, hazardous issues such as faults in electrical components or gas leakage may cause this situation. Since each cause requires a different approach, it will be helpful to explain each one separately.

Odor occurring during the first-time use of a new oven

In newly purchased ovens, a burning or chemical smell may be noticed during first use. These odors are mainly associated with the heating of protective oils and insulation materials used during production. Running the oven empty at a high temperature for 30–40 minutes during the first use can accelerate the burning of these substances and reduce the odor. This is considered technically normal and disappears after a few uses. However, if the odor persists, there may be manufacturing residues inside the device, and a technical inspection is recommended.

Burning of food residues inside the oven

After using the oven, leftover food inside gradually dries out and burns during subsequent uses, creating bad odors. These food residues accumulate in the bottom part of the oven, on the trays where cooking pans are placed, or around the edges of the glass door. When heated, the burning of these parts can cause both odor and smoke. To prevent the burning of food particles, it is essential to clean the oven regularly. Otherwise, this situation negatively affects both the functionality of the oven and the taste of the food.

Burning Smell from Electrical Cable and Components

If a strong, plastic-like burning smell is coming from electric ovens, it may indicate a malfunction in the electrical system. Such odors can result from heating of electrical cables, melting of insulation, or short circuits. These situations are dangerous and increase the risk of fire. In this case, the oven should be turned off immediately and a technician should be called. Regular inspection of electrical components plays an important role in preventing such problems.

Gas Leak or Improper Combustion Issue

In gas ovens, gas leaks or improper combustion can cause strong and dangerous odors. If the odor is sharp and unpleasant like rotten eggs, it may be a sign of a gas leak, and immediate safety measures should be taken. Uneven and yellow flames during combustion are also signs of improper burning. This can cause both odor and the release of harmful gases like carbon monoxide. In such cases, the gas line should be inspected and help should be sought from a qualified gas technician.

Dust and Dirt Accumulation in the Ventilation System

Dust and dirt accumulation in the internal ventilation system of ovens is also one of the main causes of odor. When these particles collected in the fan and air exhaust channels burn at high temperatures, a burning smell arises. This reduces the efficiency of the appliance and also affects the food. The ventilation system should be cleaned regularly so that the airflow works properly and odor problems do not occur. It is recommended to check these parts during annual technical maintenance.

Use of Incorrect or Low-Quality Cleaning Products

In some cases, the chemical substances used during oven cleaning can also cause odors. Especially cleaners not intended for ovens or those that vaporize at high temperatures can create irritating and burning smells. Such substances can also damage the internal parts of the appliance. Cleaning products specifically designed for ovens should be used. After use, the oven should be thoroughly ventilated and no residue of the product should remain.

Effects of Odor on the Oven and Food

Odors coming from ovens are not only disturbing but also have negative effects in terms of functionality and health.

• They can alter the taste of food – The smell of burnt oil and food particles can be absorbed by the food, ruining its taste.
• They affect the smell of the food – Especially desserts and aromatic dishes quickly absorb the odor, resulting in an unpleasant scent.
• They reduce food quality – Food cooked in an odorous environment may be negatively affected in terms of both taste and nutritional value.
• They can pose a health risk – Odors coming from electrical and gas components may contain harmful substances and irritate the respiratory tract.
• Long-term exposure can lead to health problems – Headaches, shortness of breath, and allergic reactions may occur.
• They can be absorbed into the inner parts of the oven – Odors can cling to the surfaces inside the oven and become permanent.
• They can shorten the lifespan of the appliance – Residual grease and dirt can damage the parts of the appliance and weaken its functionality.
• They lay the groundwork for technical malfunctions – Accumulated dirt and grease can disrupt the oven’s ventilation and heating system.
• They spoil the overall kitchen atmosphere – Odors spread throughout the kitchen, causing discomfort and making mealtime unpleasant.

For this reason, odor should not be seen solely as a matter of aesthetics and comfort, but also taken seriously from a safety perspective.

Preventive Tips to Avoid Odors

To prevent odor problems, it is important to follow certain preventive measures when using the oven. First, after each use, the inner surface of the oven should be wiped with a damp and soft cloth, and spilled or dried food residues should be cleaned immediately. A deep cleaning using vinegar and baking soda once a month helps remove accumulated grease and dirt layers inside the oven. Inspecting and cleaning the ventilation system at least once a year also ensures proper air circulation and prevents the formation of odors. The cleanliness of the utensils used during cooking should be ensured, and precautionary measures should be taken for foods that may spill over. Electrical and gas connections should be checked frequently, and in case of any malfunction, a professional technician should be consulted immediately. At the same time, only safe and high-quality cleaning products specially designed for ovens should be used so that the appliance is protected and the likelihood of unpleasant odors is minimized.
