Why Does My Microwave Smell Burnt Even After Cleaning?

Your microwave might seem clean on the outside—and even on the inside—but if it keeps giving off a burnt smell every time you heat something, there’s definitely more happening. A persistent burnt odor is not only unpleasant but can also change the taste of your food and indicate bigger problems with the appliance.

If you’ve already tried regular cleaning methods and are still looking for microwave oven repairs near me, this guide will help you understand what might be causing the issue and what you can do about it.

Common Causes of Burnt Smell in Microwaves

1. Burnt Food Bits in Hidden Spots

Microwaves have vents, cracks, and spaces under the plate where food bits can get stuck. When these small pieces burn over and over while heating, the smell builds up.

Solution:

• Take out the turntable and clean underneath.
• Use a flashlight to check corners, the vent grill, and the fan area.
• Clean with vinegar and baking soda to remove tough residues.

2. Melted Plastic or Burnt Parts

If plastic containers or covers have melted in your microwave at some time, the smell can linger for weeks, even after a surface clean.

Solution:

• Look for any melted bits or discoloration.
• Use baking soda paste or lemon steam cleaning to get rid of smells.
• If parts like the turntable ring or coupler are broken, replace them.

3. Faulty Internal Parts

Sometimes, the smell doesn’t come from food at all—it can come from overheated internal parts, like the magnetron or electrical wiring. These smells are more like chemicals or electricity.

Warning Sign:

If your microwave gives off a burnt plastic or metal smell, stop using it right away.

Solution:

Look for microwave oven repairs near me and have a qualified technician check the appliance. Don’t try to take it apart yourself.

How to Deodorize a Microwave Naturally

If the smell is food-related and not due to internal damage, here are some methods to try:

Lemon & Water Steam

• Fill a microwave-safe bowl with water and lemon slices.
• Microwave on high for 5 minutes.
• Let the steam sit inside for a few minutes before wiping clean.

Baking Soda Overnight

• Put an open bowl of baking soda in the microwave.
• Leave it overnight to soak up lingering smells.

Coffee Grounds

•  Use dry, used coffee grounds in a bowl overnight as a natural deodorizer.

When Cleaning Doesn’t Work

If none of these methods fix the issue, the smell could be stuck in the microwave's internal area, insulation, or parts. This usually happens if the unit has had overheating or many burn incidents over time.

In these situations, a professional diagnosis is necessary, not just to remove the smell but to check for possible fire risks or internal damage.
