What is in a dryer?

Answer 1

Dryers usually contain a front loading tub with holes for ventilation. This tub rotates and is powered by a belt at the back from an electric motor in the back corner. Some have a heater tunnel with an electric heater and a fan forcing hot air into the tub. Others may have a gas heater, similarly forcing hot air into the tub. There are many heat sensors and auto shut off switches in case they get too hot. Most dryer problems are caused by these switches or broken belts.

Answer 2

A dryer typically contains a drum where wet laundry is placed, a heating element or gas burner to generate heat, a blower to circulate hot air, and a lint trap to capture lint from the clothes. Some dryers also have sensors to detect moisture levels and ensure clothes are dried properly.
