Why Does My Oven Smell Like Propane? [Issues, Solutions & Guide]

Your oven smelling like propane can be caused due to several reasons. Such as a dirty oven, packaging materials being left with the oven, igniter failure, or blocked oven vents.


Although these can cause a mild odor now and then, a frequent and strong odor often indicates leakage and requires proper evaluation by contacting the appropriate authorities.

How do I know if my oven is Leaking Gas?

A consistent and strong smell of Sulphur-like or rotten egg can indicate a leaking gas and a hissing sound confirms a leakage. Leakage can be caused due to a damaged connection; when the connection is not tight and sturdy.

Spillage of water or any moisture can lead to corrosion of gas lines as well. A gas leak situation should be handled according to its severity. The usual steps that should be taken are; turning off the oven, diminishing any flames present, opening all the windows and doors to ventilate the area, and finally contacting the professionals to repair the connection.

Gas leakage can often be hazardous. Therefore, it is recommended not to use the oven with leaks even if you are unsure about it.

Is it Bad if my oven Smells like Gas?

It is not unusual for your oven to smell like gas initially when you turn it on the oven. The smell that stays for a minute or two is caused due to the combustion of the gas burner.

But the smell of an unburnt gas smelling like a rotten egg that stays more than a few minutes is not normal. These types of smells are often caused due to the failure of an igniter.

In such cases, the gas valve does not get enough current to fully open to release enough gas to ignite the flame for the first few seconds but eventually lights up. Therefore, igniters need to be checked and changed whenever needed.

Why Oven Smell like Gas when Preheating?

The gas smell after preheating can also be due to igniter failure or leakage. When new ovens are installed, there may be leftover packaging materials that melt and burn when the oven is preheated. Oven odors can also be the reason behind a dirty oven.

Not cleaning the oven regularly or clearing up the spills after every use can cause a decomposition of debris that may burn or disrupt the gas flow of the oven. The blockage of the oven vents with a mat and food residue can also create the same problem.

Why Does My Oven Smell Like Propane?

Ovens are often insulated with a material that emits a propane-like smell when heated at the first use, but the presence of smell when not in use is not normal. It means there is a leakage.

The smell of propane is often intentionally added to the natural gas to understand the presence of any leakage that needs to be fixed. Smelling propane can be dangerous and investigated when the gas is turned off.

Can a Propane Oven Smell like Kerosene?

A cooker or a propane oven often emits a harmful source of volatile organic compounds (VOCs) that may smell like kerosene. The presence of petroleum products such as paint or oil is the most typical cause of a kerosene odor in homes.

When drying paint comes into contact with natural gas from your stove, it emits a kerosene-like odor. But, once there are no drying paints, you should take precautions. Cooking, in general, can release toxic substances because cooking involves combustions appliances.

While heating oils and fats can also release harmful nitrogen dioxide and carbon monoxide (VOCs). Cooking generates extra heat, which can contain VOCs such as formaldehyde to escape into your kitchen.

Gas Oven Smells like Burning Plastic: What could be the Reason?

New ovens always have a plastic-burning smell due to the insulation cavity of the oven the first time being exposed to heat. Secondly, if you forget to open the plastic zip tries of your oven.

New ovens often use zip ties to secure the grills and other oven parts while transporting it. If you forget to notice them, you may be burning it every time the oven is in use.

If you are actually gone through the haphazard of burnt zip ties, the steps that you should take to get rid of these burnt zip ties.

  1. Turn of the oven, remove the extra inserts from the oven and let them cool down (Put ice for fast cooling)
  2. When it is cooled, use a scraper to remove zip ties, the residues from inserts, and the oven cavity.
  3. Use a mild detergent and a scrubbing pad to clean down everything.
  4. Use a microfibre cloth to wipe out the oven cavity and the inserts and leave them for 30 minutes to dry out completely.
  5. After everything is dried out completely, put an odor absorbent (e.g., White vinegar) in a cup or bowl and keep it inside the oven for an hour with the door closed.
  6. Now, bring the absorbent out of the oven to get an odor-free fresh oven.

The oven may smell like plastic due to the wiring issues as well. If your oven is not brand new and the smell only arises when baking it could indicate a problem with the electrical wiring.

Such issues arise when there is an electrical malfunction causing short circuits, resulting in melting its insulation in the process.

Other oven components may also burn out, leaving a terrible rubbery or plastic-like odor due to a wiring issue. Unplug the oven and check for any burnt wiring insulation or other components. If any, contact the professionals to solve the issue.


Q. Why does my stove smell like propane?

It may be due to a dirty oven, packaging materials being left within the oven, failure of the igniter or blocked oven vents.

Q. Why Does My Gas Oven Smell Like Propane?

A gas oven smelling like propane is not normal. Propane odor is intentionally added with the natural gas that doesn’t have an odor. The foul propane odor is added as an indicator of any leakage.

Q. Why Does My Electric Oven Smell Like Propane?

For electric ovens, the smell of propane is normal to get when the first time it is exposed to heat. The insulation around the oven cavity heats up; it produces a propane-like smell.


Oven smelling like propane, kerosene, or plastics can be due to similar reasons. Preheating may often release a smell of propane or plastic, depending on the root issue. It can be due to a leakage of gas that has a propane dour within it, the melting of zip ties, packaging plastics, or a malfunctioning wire. An oven odor can be very usual and very severe, resulting in dangerous circumstances depending on the root cause. Therefore, an oven should be frequently analyzed and contacted by professionals whenever there is confusion.
