What Causes An Oven To Blow Up?

When using or cleaning your oven, you can unintentionally crack the glass, which would set off an explosion. According to your oven’s instruction manual, any scourer can leave tiny scratches on tempered glass, making it more prone to shattering.

Different materials expand and contract at varying rates in response to temperature changes. Because of this, anything that comes into contact with the glass when it heats up and cools down could encourage the explosion of ovens.

Some potential causes of oven blow up are discussed in this article:

What Causes An Oven To Blow Up?

Oven explosions are uncommon, but they’re also not unheard of. It is capable of exploding suddenly. Uncertainties in the system can cause an oven to explode. However, no one is able to provide an electric gadget guarantee.

Ovens can blow up unexpectedly, sending glass shards flying across your kitchen or into your food. Never bang pots and pans against the oven door. A stress fracture can be created by even the smallest crack or Nick and subsequently “blow up.” There are several reasons why ovens can explode, including:

  • Overheating 
  • Electrical arcs 
  • Tempered glass
  • Uncovered wires
  • Leaking gas

Therefore, you must ascertain the causes of the explosion in your electric or gas oven and the outcome. You must also decide how to respond to the circumstance. How to reduce the risk is a crucial question that you must address for your own safety.

What Does Cause An Oven Explosion?

Despite being generally safe equipment, microwave misuse can result in flames and explosions.

The usual reasons for such mishaps are listed below.

Use Of Metals For Cooking

According to any microwave oven’s instruction manual, metal containers are not recommended for microwave cooking.

The atoms of metals contain free electrons. These electrons vibrate quickly when exposed to microwaves. The metal becomes heated as a result.

The metal will continue to heat up as the temperature rises until it reaches a point where it can burn the oven heating element. Now, an explosion or fire is not always started by this.

Therefore, it might be okay if you unintentionally leave a metal container in the microwave. But typically, this is due to the metal’s thickness, as the dense metal heats up very slowly.

When the metal has jagged edges or uneven surfaces, a problem develops. Concentrated negative charges are created when free electrons bounce off an uneven surface.

Sparks develop when these charges come into contact with air atoms. If those sparks come in contact with something flammable, they may cause an explosion or fire.

Never use metals inside the microwave since you can’t tell when this may happen.

Cooking Specific Foods

Due to their shape and structure, many foods, like grapes and eggs, can cause microwave fires.

When you attempt to cook an entire egg in its shell, issues occur. There is very little room inside it for the food to cook because the shell is still intact.

The moisture inside the egg becomes steam when microwaved, increasing the pressure.

The egg explodes due to a shortage of room and internal pressure.

Construction Flaws or Wiring Issues

When building this equipment, most microwave oven manufacturers prioritize safety concerns.

A safety certification proves that a microwave oven complies with industry standards for safety. Such devices carry lower accident risks.

The robust design and security features ensure that the gadget will turn off in the event of any unforeseen problems.

However, the device could occasionally explode or catch fire due to a manufacturing flaw, such as a faulty temperature sensor. Therefore, before purchasing a model, look for similar prior complaints.

Installation problems can also result in explosions or fires. Accidents using microwaves may be caused by an electrical overflow.

Short circuits or sparks caused by faulty wiring may harm the device.

How To Prevent An Oven Explosion?

Understanding how to use the microwave oven properly and adhering to manufacturer directions are the best ways to prevent accidents.

Ad adheres to the following recommendations to avoid fires and other harmful microwave oven mishaps.

  • When deciding on a power supply for your microwave oven, follow the instructions from the manufacturer. Always use a wall socket with the specified rating to prevent short circuits or electrical damage to the device.
  • To heat or cook food in the oven, only use microwave-safe containers. Avoid using aluminum foil or anything with metal rims or other metallic surfaces.
  • Never put anything flammable, such as paper or cloth, on or next to the microwave.
  • When cleaning equipment, always disconnect it. All surfaces should be cleaned well and often to lower the fire risk.
  • Cooking various delicacies requires adhering to precise directions and rules. Burning or worse, accidents will be avoided.
  • Be careful when putting something in or taking something out of the microwave. Wear the appropriate gloves or safety equipment to prevent burns and injuries from hot food.
  • Children should not operate the microwave without an adult present.

Can An Electric Oven Blow Up?

Electric stoves can catch fire. This, however, is a rare occurrence. You should be able to avoid an electric stove explosion in your kitchen with general maintenance.

An electric stove explosion can occur if the coil range element on your stove becomes loose and develops broken wires, if the heating elements socket or coil becomes damaged, or if the element is simply defective. The result can be as minor as a spark or dramatic as an electric oven explosion.

Prevent electric stoves from exploding by doing the following:

  • Looking for any loose or broken wires.
  • Avoid using large pots or pans on small burners.
  • Examining the coils for damage.
  • Monitor your electric ovens for signs of trouble, such as sparks.
  • Maintain old or infrequently used appliances.

Can A Microwave Explode Even When Empty?

What you put in a microwave will usually cause it to explode. It is extremely uncommon for them to blow up empty.

To begin with, very few people switch on a microwave when it is empty. The microwave can’t blow up since there is no power flowing.

If you frequently turn on your microwave even when it is empty (you should stop, you’re wasting power), it will eventually break and even explode.

There must be a place for all those microwaves. They will all bounce around and absorb the microwave if there is nothing to absorb them, which might cause a fire or an explosion.

What Might Ruin a Microwave?

If you utilize a microwave appropriately, it is durable and difficult to harm. Your microwave will become unusable if you:

Connect It To The Incorrect Power Source

Make sure your microwave is connected to the main power in your area. Other countries worldwide utilize 240V mains power, whereas the US uses 120V.

It is dangerous to plug a 120V microwave into a 240V power source. A fuse blowing, heating elements explosion, or some smoke could damage your microwave oven.

Run It For A Longer Duration Once Empty

Long-term use of any electronic device is never recommended. This issue can also arise with microwaves, especially if you run one for an extended period with nothing inside. The load on electronics and the magnetron will be enormous.

Putting Incorrect Items In The Oven

Throwing the wrong stuff into your microwave is the final and possibly most frequent cause of failure. Either fire will break out, or the device’s electronics will become overworked and damaged. The following items shouldn’t be placed in a microwave:

  • Metalized foil
  • Both plastic containers and bags
  • Plastic bags
  • Portable mugs
  • Uncooked eggs
  • Grapes
  • Spicy peppers
  • Containers without lids
  • Containing food in airtight containers

Precautions To Prevent A Gas Stove Explosion

Explosions caused by gas stoves are easily avoidable. Here are some precautions you can take to avoid gas stove explosions:

  • Place a gas leak detector near the stove. A carbon monoxide detector will assist you in detecting a gas line leak before it becomes too dangerous.
  • While in use, keep the proper distance between your burners and any combustible materials. Electrical appliances such as microwaves, ovens, refrigerators, and lit cigarettes fall into this category.
  • Regularly check for signs of corrosion, rust, or other damage to ensure no gas leaks.
  • To clean the only gas stove, never use a flammable liquid.
  • Even if the burner is set to low, never leave a pan on the burner unattended while cooking.
  • Installing gas ovens in an area with excessive dust, dirt, or other combustible materials that could be drawn into the venting system is not recommended.
  • Always double-check that your gas stove is properly turned off before going to bed or leaving the house.
  • Regular servicing of your gas ovens will go a long way toward preventing problems.


What does it mean when your oven pops?

The heating and cooling of the metal during the cooking or cleaning procedures results in “cracking,” “popping,” or “oil canning” sounds, which are natural.

Why did my electric oven pop?

There may be popping or crackling sounds emanating from the oven due to the heating and cooling of the steel and porcelain and the movement of the electric elements in their mounting brackets.

What happens when an oven element blows?

The majority of ovens have both a lower and an upper element. Cooking food will take longer until the dead element is replaced. Nothing “happens”; it appears to have been “turned off,” which it has been.

Can an oven explode if left on?

The heat from an oven left on for a long time might build up and ignite a fire. It’s crucial to use caution when cooking at high heat because this is more likely to occur if the oven is set to a high temperature. Generally speaking, turning off the oven when not in use is preferable.

Do ovens turn off on their own?

Most touch-pad clock-controlled stoves and ovens turn themselves off automatically after 12 hours. If the oven is unintentionally left on, this has the advantages of peace of mind and energy savings. There is no automatic shutdown for models that lack a clock or timer.


Sometimes an oven explosion goes too far and damages you. So, keep alert before it’s too late. Take a photo of your blown-up oven and the broken glasses landing on the floor before the oven, even if this disaster happens.

If a warranty still covers your product, that can assist you in seeking free service from the manufacturer. The most important thing is keeping people safe, so if anything isn’t working right, always call in an expert.
