Some household appliances, especially air fryers and toaster ovens, can pose hidden risks—even when not in active use.

These devices can overheat or suffer electrical malfunctions simply by being plugged in. This makes them potential fire hazards if left unattended for long periods.

A growing number of incident reports point to poor internal components or cheap wiring in certain models. Over time, these parts may fail, leading to short circuits or even spontaneous ignition.

Unlike large kitchen appliances that are typically built to rigorous standards, some small countertop devices don’t have the same level of quality assurance.

Leaving these gadgets plugged in overnight or while you’re away increases the risk significantly. It’s especially dangerous if your wall outlets are older or ungrounded.

Power surges can also cause a sudden fault in the appliance. Without a surge protector, a faulty device might trigger sparks or even flames.

Beyond air fryers and toaster ovens, other appliances you should be cautious about include electric kettles, coffee makers, and aging microwaves.

Experts emphasize that air fryers and toaster ovens have been involved in more reported household fire incidents in recent years, likely due to their surge in popularity.

To reduce the risk, unplug these appliances after use. Make sure they cool down on a heat-resistant surface and keep flammable items far away.

Also, consider using smart plugs with timers or built-in surge protection, especially if you often forget to unplug devices manually.

Small safety habits—like checking cords for wear and keeping outlets clear—can make a major difference in preventing a dangerous situation from unfolding in your home.
