Mounted on the heat exchanger\/blower deck, this primary high-limit switch monitors supply-air temperature and opens the circuit to shut off the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or a failed blower. It is the furnace's main overtemperature safety and directly protects the heat exchanger from thermal damage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit temperature control (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed, open-on-rise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Supply-air overtemperature safety cutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Heat exchanger \/ blower deck limit position\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Goodman \u0026amp; Amana furnaces incl.
