The bad news is: your oven is calling out for help. Let’s dissect the most popular reasons for that ugly smell and what they might be telling you.
1. New Oven Smell
If your Oven Smells Bad the first few times you operate it, don’t worry. This is usual with new ovens installed.
Causes:
Factory coatings, oils, or insulation materials burning off during initial uses.
Residues from leftover packaging.
What to Do:
Empty oven run at a high temperature (around 400°F/200°C) for 30-60 minutes to burn out residues.
Have the kitchen well ventilated when doing the above.
Tip: Always read the manufacturer’s “burn-in” instructions before cooking with your oven.
2. Burning Plastic Smell
This is one of the most dangerous smells your oven can produce.
Possible Causes:
Forgotten packaging, plastic trays, or containers accidentally left inside.
Wires or insulation in close proximity to heating elements melting due to a malfunction.
Is It Dangerous?
Yes. Burning plastic produces toxic fumes and will hurt your oven.
Fix:
Switch off the oven right away.
Allow it to cool and check the interior.
If you can’t see any plastic, have a technician come out and check internal wiring.
3. Gas Smell from Gas Oven
If you have a gas oven and it has a gas smell, a rotten egg or sulfur smell, take it VERY seriously.
Probable Cause:
Gas leak or incorrect usage.
Quick Action:
Cut off oven power and open windows.
Don’t turn on lights or use electronics.
Contact your gas utility or appliance repair person ASAP.
Reminder: New gas ovens in 2025 also usually come equipped with safety sensors. If your sensor is beeping or flashing error messages, believe it.

This usually indicates internal malfunction.
Causes:
Damaged wires or failing parts.
Overheated internal wires or faulty fans.
Solution:
Disconnect the oven or switch off circuit breaker.
Do not operate until checked by a qualified technician.
Warning: Electrical odors usually are a warning sign for fires. Never neglect them.

Occasionally the cause of an unpleasant oven odor is quite straightforward: the oven needs to be deep cleaned.
Evidence:
Persistent burnt smell when cooking.
Smoke or steam from concealed spills.
Solution:
Give the interior a good cleaning, particularly around the bottom element.
Baking soda and vinegar or a specialized oven cleaner can be used.
Pro Tip: In 2025, most smart ovens have auto-clean or steam-clean settings. Use them with frequency.
6. Mold or Musty Smells
Unusual but possible, particularly in unused ovens.
Why It Happens:
High humidity and inadequate ventilation.
Food particles or grease that didn’t completely burn off.
Solution:
