What will de-energize the entire dryer when the temperature exceeds 205 degrees Fahrenheit?

The safety thermostat serves as a critical component in a dryer's temperature regulation system. When the temperature exceeds a predetermined threshold—in this case, 205 degrees Fahrenheit—the safety thermostat is designed to disrupt the electrical circuit of the dryer. This action effectively de-energizes the entire appliance, preventing overheating, which could lead to potential fire hazards or damage to the dryer itself.

By stopping the flow of electricity, the safety thermostat helps ensure the safety and longevity of both the machine and the user. This safety feature is essential in appliances where high temperatures are a regular occurrence, as it intervenes automatically to avoid dangerous conditions.

In contrast, other components like the temperature probe, overheat relay, and fusing element may play various roles in monitoring, signaling, or interrupting electrical flow under certain conditions, but they do not perform the specific function of completely de-energizing the dryer when high temperatures are detected.
