Mounted on the heat exchanger or blower deck, this temperature-sensing switch opens the control circuit if supply-air temperature exceeds its \u003cstrong\u003e150°F\u003c\/strong\u003e setpoint — protecting the heat exchanger from overheating due to restricted airflow, a dirty filter, or a failed blower.
