Understanding the Dryer Heating Element
Before we dive into the issues surrounding a faulty heating element, it’s essential to understand what it is and its significance in the drying process.
What Is a Heating Element?
A dryer’s heating element is a crucial component responsible for generating heat that dries your clothes. It is typically made of coiled metal and is located in either the dryer’s drum or the air flow section. When the dryer is powered on, electricity flows through the heating element, causing it to heat up and dry the clothes as they tumble in the drum.
How the Heating Element Works
The heating element works in conjunction with a thermostat and other components such as the thermal fuse and timer. Here’s how the process usually works:
- The dryer is set to a drying cycle.
- The thermostat detects the temperature of the air in the drum.
- If heat is needed, it activates the heating element.
- As the clothes dry, the thermostat continually monitors the temperature.
- Once the desired temperature is reached, the thermostat turns off the heating element.
This simple yet effective cycle makes your dryer an invaluable appliance. However, when the heating element fails, the entire drying process can come to a standstill.
