Goodman 10728342SP 3" Insert Limit Switch

The Amana-Goodman 10728342SP 3" Insert Limit Switch is a temperature-actuated safety control used in furnace and air handler assemblies. It is designed to monitor internal heat conditions within the airflow path and respond when preset thermal limits are reached. Installed as an insert-effective probe within the equipment housing, it provides a response to the control circuit by opening or closing the electrical path when excessive temperature is detected. In HVAC systems it helps prevent overheating of the heat exchanger and supports safe shutdown behavior during abnormal operating conditions.
