This L170-30F fan disc control acts as a thermal safeguard by monitoring internal equipment temperatures. When the heat exceeds a safe threshold of 170°F, the switch automatically opens to cut power to the heating element or burner, preventing overheating and potential system damage. Featuring an automatic reset functionality, the switch restores the electrical circuit once the temperature drops by 30°F.
