What Causes An Oven To Blow Up?

Electric ovens use electricity rather than natural gas to generate heat and cook food uniformly and cheaply. Even though they do not require gas, electric ovens can catch fire. This is because overheating, exposed wires, electrical sparks, and unsecured connectors may cause the air to heat up and expand quite quickly. Extreme heat can not only harm the internal components of your oven, but it can also cause the glass on the inside area of your oven to crack.

When you use or clean your oven, you may accidentally damage the glass, causing the oven to explode. Any type of scourer can create small scratches on the surface of the glass, making it vulnerable to shattering, as stated in your oven’s instruction manual.

Temperature changes cause various materials to expand and contract at different rates. As a result, anything that comes into contact with the glass as it heats and cools might promote the development of flaws. Make sure the item you’re cooking does not come into touch with the glass door, clear off any cooking filth from the glass, and prevent drying damp towels on the handle.

Can an electric oven blow up?

Yes. 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. The tiniest crack or Nick can produce a stress fracture, which can “burst up” later. Electric ovens can blow up for a variety of causes, including:

  • Overheating 
  • Loose Connections
  • Tempered glass
  • Electrical arcs
  • Exposed Wires, etc

Why does the electric oven Blow up?

When the heating element in an electric oven blows up, there are four potential causes. Tempered glass, overheating, exposed wires, loose connections, and electrical sparks are examples of these.

For safety reasons, many prefer electric ovens to gas ovens. Although electric ovens are safer to operate than gas ovens, the heating components in an electric oven may blow up.

Note: You should never take an exploding heating element lightly, even though the appliance doesn’t rely on gas. 

Tempered Glass

Ovens glass is stronger and more resistant to heat and mechanical stress than conventional glass, and it is less likely to shatter under these conditions. This is critical for ovens and cookers, which must withstand temperature fluctuations and frequent usage.

  • Tempered glass is thermally toughened by heating it to over 600 °C and then rapidly cooling it.
  • The outer layer of the glass cools faster, resulting in a compressed outer layer. This protects the interior of the glass, which cools more slowly.
  • Tempered glass, on the other hand, is still fragile and can shatter. When it happens, it usually does so abruptly and brutally. While this might be frightening, tempered glass shatters into smaller, blunter bits than regular glass.
  • There are several reasons why tempered glass in an oven may shatter, but pinpointing the specific cause is typically difficult. This is due in part to the fact that glass breakdown can occur a long time after the initial damage caused by a knock.


The second cause of an electric oven blowing up is that it has overheated far beyond what the element can handle. An oven heating element will overheat as a result of:

  • A damaged thermostat mistakenly transmits to the oven a higher temperature than the one you’ve set.
  • Because of a faulty relay on the main control board, the heating element operates when it should not.
  • A faulty temperature sensor does not detect high temperatures and so does not turn off the oven to prevent it from overheating.
  • The heating element consists of a ribbon, wire or strip with high electrical resistance.
  • As electricity runs through the high-resistance materials that are distributed throughout your oven chamber, they will create a lot of heat.
  • Because a lot of power passes through high-resistance materials, they can be harmful.
  • They’re usually contained behind an outer sheath that prevents the material from coming into direct touch with your fingers or the oven’s other metal parts.

Loose Connections

Another cause of the electric oven blowing up is loose connections. Loose connections indicate a faulty electrical connection between the power source of the oven and the heating element itself.

  • When the heating element is securely linked to its power source, electricity flows freely.
  • A faulty electrical connection generates considerable resistance, making it extremely difficult for electricity to flow freely.
  • As a result, the temperature at those connections will rise considerably. This will result in an electrical fire and explosion, among other catastrophic consequences.
  • turn off the appliance completely If you suspect weak connections, place the oven in the oven and leave it to cool for an hour.
  • After that, remove the heating element to verify its connections.
  • Some dirt or debris may have accumulated around the connectors, preventing you from fully inserting them.
  • Clean them as thoroughly as you can using a brush. lastly, shove

Final Verdict

While electric oven explosions are extremely unusual, electric oven owners must be well-informed about what causes electric ovens to explode, how to prevent such explosions, and what to do if one occurs. The most essential thing is to keep people safe, so always seek expert assistance if you believe anything isn’t working properly.
