Mounted on the heat-exchanger bulkhead, this primary limit monitors supply-air temperature and opens the circuit to shut off the burners if the plenum overheats — typically from restricted airflow, a dirty filter, or a failed blower. It is a core safety component that prevents heat-exchanger damage and fire hazards.\u003c\/p\u003e\u003cp\u003eSymptoms of a failed primary limit include short-cycling on the limit, a furnace that heats then shuts down, or no heat at all.
