You should know this as soon as possible to avoid risks.
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.
