Microwave 12

Microwaves are an integral part of our kitchens. They offer a convenient and quick way to heat food, make popcorn, or even defrost frozen items. However, like any other electrical appliance, microwaves also come with a risk of fire. In this comprehensive guide, we’ll cover what to do if your microwave catches fire, how to prevent microwave fires, and other useful tips to ensure your safety.


If your microwave catches fire, immediately turn off and unplug the microwave, but keep the door closed to starve the fire of oxygen. If the fire doesn’t extinguish on its own or if it seems to be getting worse, call the fire department. After the fire is out, ventilate the area, inspect for damage, and clean the microwave thoroughly.

Immediate Steps to Take if Your Microwave Catches Fire

If you notice your microwave on fire, acting quickly and appropriately is crucial. Here’s what to do:

  1. Keep the Door Closed: Resist the urge to open the microwave door. Doing so can introduce oxygen and fan the flames, making the fire spread.
  2. Turn Off the Microwave: Immediately turn off the microwave. This action shuts off the fan that could potentially feed oxygen to the fire.
  3. Unplug the Microwave: If it’s safe to do so, unplug the microwave from its power source. This step disconnects the power supply, reducing the chances of the fire escalating.
  4. Let the Fire Burn Out: Microwaves are designed to starve fires of oxygen, causing them to extinguish naturally. Leave the door closed, and allow the fire to burn out.
  5. Call the Fire Department if Necessary: If the fire seems to be getting worse or you’re unsure whether it’s completely out, call your local fire department immediately.

Preventing Microwave Fires: Safety Tips

Prevention is always better than cure. Here are some tips to prevent microwave fires:

  1. Use Microwave-Safe Containers: Always use microwave-safe containers and avoid using metal utensils, aluminum foil, or any non-microwave-safe materials in the microwave as these can spark and cause a fire.
  2. Follow Manufacturer’s Instructions: Adhere to the manufacturer’s instructions for using and cleaning your microwave.
  3. Avoid Overheating: Be cautious when heating items like popcorn or heating pads. Follow the manufacturer’s instructions and avoid overheating.
  4. Never Leave Your Microwave Unattended: Always keep an eye on your microwave when it’s in use.

Potential Causes of Microwave Fires

Understanding the potential causes of microwave fires can help prevent them. Here are some common causes:

  • Overheated food or packaging
  • Metal objects in the microwave
  • Faulty components or wiring
  • Use of improper, non-microwave-safe materials
  • A faulty power cord or outlet

Post-Fire Precautions

After a microwave fire, it’s essential to take certain precautions:

  1. Ensure the Fire is Out: Wait until you’re certain the fire is completely extinguished before opening the microwave door.
  2. Unplug the Microwave: Disconnect the appliance from the power source.
  3. Ventilate the Area: Open windows and doors to get rid of smoke and fumes.
  4. Inspect for Damage: Once the microwave has cooled down, inspect it for any visible damage. If you find any, it’s best to replace the microwave.
  5. Clean the Microwave: Clean the microwave thoroughly before using it again.

In conclusion, while microwave fires can be scary, knowing what to do can help you handle the situation safely and effectively. Remember, the best way to handle a microwave fire is to prevent it from happening in the first place. Regular maintenance and proper usage are key to ensuring your microwave remains a safe and convenient tool in your kitchen.
