Microwave Odors

Microwaves can retain odors from what's being heated inside. A new microwave can also have a smell during its first uses. Regardless of the cause, there are steps to take to get rid of the odor.
 

New Microwave Smells

There are several reasons for getting a "new microwave" smell when it's being used. Below are the most common causes.
  • An electrical odor in new machines can be normal because the electronic board is "curing" as the circuit board material is heated for first few uses.
  • A strong burning, oily smell or a little smoke is normal when using Convection BAKE, Convection ROAST or Combination Fast Cook for the first few times. The smell comes from the new convection heater and will go away with regular use. If this smell does not dissipate after multiple uses, service is recommended.
 

Cooking and Burned Food Odors

Clean up spatters and spills as they occur.
 
  • We recommend cleaning the inside cavity with baking soda or a non-abrasive detergent, and letting it dry.
  • For strong odors, try leaving the door open for 2-3 hours when the microwave is not in use to let the microwave "air out." Some extreme odors like fish or burned popcorn may take several days to wear away.
  • If the smell or odor persists, try the following:
    1. Mix 6 tablespoons of baking soda and one cup of water or mix a solution of 1/2 cup lemon juice and one cup of water.
    2. Place either solution in a microwave safe dish of appropriate size and heat for 2 to 3 minutes on high power.
    3. Don't open the door immediately. Wait for at least 15 minutes, and then open the door and wipe out the moisture in the interior with a dry cloth.
 

Electrical Burning Smell

  • If you see arcing or sparking in the microwave and smell an electrical odor, it could be that metal was accidentally used the the microwave. Stop the appliance and check for metal paint, twist ties, etc. For more information on what to look for, check out: Microwave Arcing In Cavity.
  • If there is a burning smell not from food, especially if it is an electrical or chemical odor, stop the microwave. Check the electrical outlet and unplug the microwave if there is visible burning near the plug, cord, or outlet. We recommend having one of our appliance technicians check your microwave.
