The kitchen appliance you should unplug before going to sleep to avoid a fire is usually the air fryer or sometimes toaster ovens.

Why?

These devices can overheat or have electrical faults even when not in active use.

Some air fryers and toaster ovens have poor wiring or cheap internal components that might fail over time, leading to short circuits or spontaneous ignition.
Leaving them plugged in overnight increases the risk of electrical fires, especially if your outlet isn’t top quality or if there’s a power surge.

 Other risky appliances include: electric kettles, coffee makers, and old microwaves — but air fryers and toaster ovens are especially emphasized lately because of rising incident reports.
