Microwave fire damage occurs when a microwave oven malfunctions or is improperly used, leading to a fire hazard. While microwaves are designed to be safe, they can catch on fire if certain conditions are met, such as overheating food, using non-microwave-safe containers, or improper maintenance. For instance, when food is heated for too long or at too high a setting, it can catch on fire, potentially causing extensive damage. It’s also crucial to avoid leaving the door open while the microwave is running, as this can disrupt the cooking process and lead to overheating. Understanding the causes of microwave fire damage, prevention strategies, and safety measures is vital for ensuring safe usage and avoiding dangerous situations. Properly using microwave-safe materials and regularly checking the appliance for any issues are key practices in preventing these risks.
Why Microwaves Can Catch Fire and How to Avoid It
Microwave fires can happen for a variety of reasons. Understanding these common causes and following preventive measures can help keep your microwave safe to use.
Common Causes of Microwave Fires:
- Faulty Wiring or Electrical Issues: If there’s an electrical malfunction or faulty wiring within the microwave, it can cause overheating, leading to potential fires. These issues can be hard to detect without professional inspection.

Post-Fire Precautions
- Keep the Area Clear of Flammable Materials:
After the fire is out, remove any nearby flammable materials from the microwave and surrounding area. This includes paper towels, napkins, or plastic objects that could catch fire if the microwave is used again before it’s checked for damage. - Ensure the Microwave Is Unplugged After the Fire Is Out:
Once the flames have been extinguished and the microwave has cooled down, unplug the appliance from the power source. This step helps prevent electrical issues or potential fires from reigniting due to faulty wiring.
Simple Steps for Cleaning a Microwave After a Fire
Assess the Damage

What if These Steps Don’t Work to Put Out a Microwave Fire?
While it’s important to act quickly and follow the right procedures when a microwave fire occurs, there may be situations where the fire cannot be controlled using standard methods. Here’s what you should do if your efforts to put out the fire are unsuccessful.
When Fire Extinguishing Methods Fail
Even with immediate actions like closing the microwave door, using a fire extinguisher, or attempting to smother the flames with baking soda or a wet cloth, some fires may continue to spread or worsen. These cases could be due to several factors:
- Electrical Fires:
Microwaves are powered by electricity, and electrical fires are often harder to manage than regular fires. If a short circuit or internal electrical fault causes the fire, it may be difficult to put out using common fire suppression methods. Electrical fires can also reignite after you think the fire is out, especially if the microwave is still plugged in. - Internal Wiring or Components on Fire:
If the internal components of the microwave, like wiring or circuit boards, catch fire, these fires can spread rapidly. These types of fires are typically not something you can control at home, especially since they might be hidden within the microwave’s structure and difficult to reach without professional help. - Flammable Materials Inside the Microwave:
If flammable materials inside the microwave (such as certain plastics or paper products) catch fire, the situation may worsen quickly. These materials can cause the fire to grow uncontrollably, even if you try to cover the flames with a wet cloth or other methods. - Too Large a Fire to Manage Safely:
Sometimes, a fire may simply grow too large or intense for home extinguishing methods to be effective. If the fire is consuming more of the microwave’s interior, or if it spreads to surrounding kitchen areas, the risk to your safety increases. In such cases, using a traditional fire extinguisher or relying on water or baking soda may no longer be effective.
Signs You Should Not Attempt to Put Out the Fire Yourself
While it’s natural to want to act quickly and control the situation, there are certain signs that indicate you should stop attempting to put out the fire and instead call emergency services:
- Fire Spreading Beyond the Microwave:
If the fire starts to spread beyond the microwave to other kitchen surfaces, cabinets, or nearby appliances, you should not attempt to control it yourself. The fire has likely grown too large and is out of your reach. Evacuate the area and call 911 immediately. - Thick Smoke or Dangerous Fumes:
If the microwave produces thick smoke or releases dangerous fumes, it can be a sign that there is a chemical fire or an electrical fire. At this point, the fire is likely uncontrollable without professional equipment. Smoke inhalation is also a serious risk, so avoid being near the area and call emergency services right away. - Electrical Sparks or Visible Flames from the Microwave:
If you notice sparks or flames coming from the microwave, particularly around the vents or power supply, this is a strong indication of an electrical fire. These types of fires can be unpredictable and hazardous. Do not attempt to open the microwave door or unplug it yourself, as electrical sparks can lead to further risk. Instead, evacuate the area and contact fire services. - Fire Extinguishing Methods Aren’t Working:
If you’ve used methods like baking soda, a wet cloth, or a fire extinguisher and the fire persists or gets worse, it’s time to call for help. It could be a sign that the fire is deeper within the microwave or fueled by factors you can’t control at home.
