Nordyne 904574 Limit Switch extending the service life inThe Nordyne 904574 Limit Switch is a critical safety component designed for high limit temperature monitoring within gas fired furnaces. This 145F CO auto limit switch serves as a primary thermal watchdog, specifically engineered to open the electrical circuit at a fixed set point of 145 degrees Fahrenheit. By integrating a time delay relay, the 904574 ensures that the system responds accurately to abnormal heat rise and potential carbon monoxide
