4 Common Reasons Why Your Oven Smells Bad

While most emit a pleasant aroma while cooking, there may be times your oven smells bad for no obvious reason. What causes bad oven smells? The smell of gas could indicate a leak and should be fixed as soon as possible. Learn the most likely reasons your oven smells weird and how to stop odor at the source.

Oven Smells Bad? Here’s How to Eliminate Odor

Certain oven odors are unmistakable and require specific cleaning techniques to eliminate them completely. We’ll list the most common reasons your oven smells bad and detail the right odor-removing steps.

Oven Smells Like Gas

If your oven is brand new and smells like gas when it’s first turned on, it isn’t always a cause for alarm. During this first use, a small amount of gas may be released before the oven ignites. The odor should be brief, lasting no more than a few minutes.

However, if your oven isn’t new and smells like gas during use, you should turn it off immediately and consult a repair service. An odor of gas could indicate an internal leak in the oven that must be repaired before using it again. If a gas odor is detectable when the oven is off, leave the house immediately and request an emergency repair service. This kind of gas leak could be from the oven’s connection to your home supply and requires immediate attention.

Oven Smells Like Burning Plastic

Why does my oven smell like plastic? In most cases, this smell occurs when a brand new oven is used for the first time. The insulation within the oven’s cavity may emit this odor when it’s initially turned on and should quickly dissipate. 

If your oven is not new and suddenly smells like burning plastic, it’s likely due to a wiring malfunction or melted plastic. Disconnect the oven’s power and inspect it for damaged wiring that may have a burnt plastic sheath. If damaged wires are visible, they should be professionally repaired.

If melted plastic is visible inside the oven, try these cleaning tips:

  • Cold method: Allow the oven to cool so the plastic hardens. Carefully scrape the plastic out of the oven with a knife, spatula, or other scraping tool.
  • Warm method: Turn the oven on to soften the plastic. Once it’s softened, remove it with a wooden spoon.

Oven Smells Like Rotten Eggs or Sulfur

Unfortunately, an oven that smells foul could be indicative of a larger problem. Mice often choose to nest in ovens due to their warm, insulated environment, leaving a mess behind. Do other areas of your home show signs of mice infestation, such as droppings, nesting materials, or footprints? If so, it’s likely that rodents are responsible for this oven odor.

When your oven smells bad due to animal infestation, it requires specific cleaning materials. We suggest spraying or wiping down the oven’s interior with a bleach solution or a commercial product specially formulated for cleaning this type of mess. Next, if your oven has a self-cleaning option, run a complete self-clean cycle. To avoid worsening the odor, Only do this once you’ve determined that there is no liquid or debris in the oven’s fiberglass insulation.

Oven Smells After Cleaning

After a self-cleaning cycle it’s not uncommon for the oven to smell of fumes or burned debris. To avoid these odors, our oven cleaning tips recommend a natural oven-cleaning solution that’s just as effective. Wondering how to clean an oven after the self-clean cycle leaves a bad odor behind? A little elbow grease and ammonia can remove the smell.

Follow these steps when your oven smells bad after the self-cleaning cycle:

  1. Take out the oven’s racks and remove large pieces of debris with a rubber spatula. Wipe away smaller remnants with a damp paper towel.
  2. Replace the racks and place a small bowl of ammonia on the top rack. Place a pot of just-boiled water on the bottom rack and close the door. Leave the oven closed for 24 hours.
  3. Slowly open the door, remove the bowl, pot and racks and let the oven air out. Wipe down the interior and oven door with clean, hot water, using a toothbrush or steel wool pad to scrub stubborn grime.
  4. Wash the racks with hot soapy water before replacing them.
