Is It Safe to Leave My Oven On Overnight?    

It actually depends. Let’s say an empty oven has been left on overnight with its doors closed; the possibility of fire and other accidents is low. But still, bits of previously cooked food could possibly be present, so there is no 100% guarantee that accidents won’t occur. Even though the oven is completely clean, electrical malfunction, i.e., short circuits, can happen at any time.    

According to the National Fire Protection Association, an unsupervised oven is on top of the list of the most common preventable causes of fire hazards in a home:     

  • Cooking    
  • Children playing with fire    
  • Smoking    
  • Heating    
  • Electrical    
  • Candles    
  • A fireplace    
  • Dryers    
  • Flammable products in garages    
  • Christmas trees    

So, according to public safety, around 118,700 fires were involved due to cooking equipment. And these fires caused around 250 deaths and 3880 injuries. And most of these fires were caused due to negligence and leaving the cooking unattended.    

What Happens If You Leave the Oven On?  

Leaving an unattended oven on is risky. It can cause malfunction of the device or even fire breakout. But before you understand the risks of leaving an oven on. Categorically, there are two kinds of ovens that are primarily used in our kitchen:    

  • Electric oven    
  • Gas oven    

Both types of ovens can catch fire due to our negligence. So even though experts recommend that electric ovens are safer than gas ovens, there are still some potential risk factors for electric ovens too. Let’s find out:    

Risks of Leaving an Electric Oven On   

The real dangers of electric ovens occur when users decide to use their ovens to heat their homes. The oven can get overheated, and the heat of the oven could melt the temperature dial and knobs, which could later cause a fire in the kitchen. Then again, if oven mitten or kitchen towel is left near the oven before realizing your kitchen could be engulfed in fire.    

Plus, don’t think leaving the oven at a low temperature will be safer. Still, the same mishaps could happen, so it’s better to turn it off.    

Risks of Leaving a Gas Oven On    

If they are left on, gas ovens pose a more severe threat than electric ovens. If you own a gas oven, be a bit more cautious and alarmed about the risks. Gas ovens can cause both carbon monoxide poisoning and fire breakout.     

Lead to Carbon Monoxide Poisoning   

One serious accident that could cause if a gas oven is left open is carbon monoxide (CO) poisoning. What makes it most dangerous is that many don’t realize that they are breathing carbon monoxide until it’s too late. But several symptoms could alert about carbon monoxide poisoning.    

  • Dizziness    
  • Headaches   
  • Nausea   
  • Shortness of breath    
  • General weakness   
  • Confusion    
  • Loss of consciousness    
  • Blurred vision    

The symptoms of CO poisoning resemble that of a nasty case of flu.    

Can Cause a Fire Breakout   

In addition to CO poisoning, an unattended gas oven could also overheat and ignite a fire. Even in the case of a gas oven, if it’s left to heat the extended home period of time. It’s a risk for both fire and carbon monoxide poisoning. So, we suggest not to ever heat your home, leaving your oven on.    

Will My Oven Turn Off Automatically?

For decades, some oven manufacturers have included an automatic shut-off feature in their ovens. You can quickly check this by reading the oven’s manual or going to the manufacturer’s website and looking up your oven’s model number. If your oven has this feature, it should also tell you when the oven will turn off.  

In the mid-1990s, most ovens with automatic turnoff capabilities were introduced in both electric and gas ovens. Some of these features include a timer that allows you to specify how long you want your oven to cook your food. If the oven turns off automatically, you may need to manually turn it back on before it works again. However, oven models without a clock or timer will not shut down automatically.  

If you need to cook food slowly and low throughout the night, there are smart devices on the market today that allow you to turn off your oven remotely through an app. Many ovens include shut-off time and other alerts to keep your family safe.
