Why Does My New Oven Smell Like Burning Plastic

Why Does My New Oven Smell Like Burning Plastic

The main reasons behind the burning plastic odor of a new oven are not removing the zip ties, exposure of the oven’s insulation to high temperature, electrical wiring problems, and burnt plastic material.

Noticing a bad smell from a new oven you just bought is not always a bad sign. Rather it is a more common issue that can be resolved easily. So, you do not need to panic.

Why Does My New Oven Smell Like Burning Plastic

You may have observed an unusual odor filling your home when you first switched on your newly purchased oven. It is quite natural, as frightening as it may be, as long as the stench is oily or of something burning, rather than gas, which is far more dangerous.

Here are some of the reasons why your new oven may smell like burning plastic.

Did Not Remove the Zip Ties

The grills and other oven components are frequently tied with zip ties by most oven and equipment companies during delivery.

It is possible that you neglected to examine it before using it. As a result, you may have burnt these zip ties. Consequently, it caused the smell of burning plastic when you used your oven.  

Steps to Resolve This Issue

  • You need to separate all of the oven components, set them on a flat table. Then use an ice pack to solidify the melted plastic remains so you can clear them. Scrape the remains with a scraper if it was already cool.
  • Observe and remove the melted zip ties remains from the oven compartment as the ice on the components melts.
  • Thoroughly clean your oven and components with a light dishwashing solution and a cleaning pad. 
  • Use a clean microfiber towel to dry the oven compartment, then set the components out to dry.
  • Finally, fill a dish or a cup with an odor absorber like white vinegar, and set it within the oven cavity while the inserts are drying.

Exposure of the Oven’s Insulation to High Temperature 

The insulation around the oven cavity has been exposed to high heat for the first time. As a result, it triggers a burning smell.

Moreover, burning off the protective oil coating employed during the manufacturing process can be the reason for it.

Steps to Resolve This Issue

  • Wipe off the oven cavity and insert with warm soapy water and a microfiber towel or a standard kitchen towel.
  • Prepare a white vinegar-water solution or a lemon-water solution in an oven-safe basin or container and bake it.
  • Remove the bowl once the self-cleaning cycle has been completed for around half an hour.

Electrical Wiring Problem

When your oven’s wiring short circuits due to an electrical issue, the insulation melts, causing complications. Additionally, other oven components may also fire as a result of a short circuit, leaving a terrible, burnt rubber or plastic-like odor.

Steps to Resolve This Issue

  • Remove the oven from the electrical outlet.
  • Look for traces of burnt wire insulation or oven components in the interior.
  • If there are any, contact an expert to diagnose and repair the issue.

Burnt Plastic Material

The unpleasant odor may be the result of a plastic container melting away in your oven that you forgot to take out.

Steps to Resolve This Issue

  • Allow the oven to cool completely before removing the molten plastic. You can use cold packs to speed up the procedure, much like you did with the molten zip tie removal.
  • Remove the racks and peel them off once it has cooled and formed the residue. Carry out the same procedure for any remains that may have gotten into the oven cavity.
  • Scrub the interior of your oven using a warm soapy mixture of water and a dish-friendly scrubber, as well as the racks.
  • Using a clean cloth, wipe the oven and the components.
  • To deodorize your oven, sprinkle baking soda on a dish and place it inside for a few hours.

Breaking In Your New Oven

The first thing you should do regardless of the type of oven you have is detach any zip or twist ties. After that, clean any racks and the interiors of the oven with soap warm water, and a cloth.

The process of burn-in needs to begin after cleaning the interior of the oven thoroughly.  Although instructions differ by manufacturer, the basic principle of every “burn-in” procedure is the same:

  • Turn on the ventilation hood’s fan. Then, if feasible, open a couple of windows nearby.
  • Preheat the oven to a high temperature of 400-550 degrees Fahrenheit (204 to 288 degrees Celsius).
  • Allow the oven to heat up to this temperature for 30 minutes to an hour

Sometimes the smell does not go away after the first cycle. In that case, you need to perform the procedure one or two more times. If you notice no smell then you can proceed to the next step. Finally, allow the oven to cool completely before wiping off the interior with a warm, soapy damp towel.

Natural Remedies for the Smell

There are a few household elements that you can use to get rid of the burning smell.

  • Mix white vinegar with water, put on the lowest rack, then use your oven’s self-cleaning feature to remove burnt plastic and other scents. All of the scents will be absorbed by the steam, leaving your oven’s inside cleaner than before.
  • Mix 1/2 cup newly squeezed lemon juice, 1/8 cup baking soda, and two cups water in a container and set it in your oven to eliminate unwanted oven odors. The steam will remove the aromas and leave your oven with a pleasant citrus scent.


Do you have to clean a new oven before using it?

You should clean the interior of an oven before it is used for the first time, and a burn-in period may be necessary. Any food baked in the oven before the first usage or burn-in procedure is completed should be discarded. During the burn-in process, oven racks can be left within the oven.

Other than these, there are a few more reasons that can lead to the smell of burning plastic in your oven.
