Mounted on the heat exchanger bulkhead, this auto-reset switch monitors supply plenum temperature and shuts off the burners if the furnace overheats — most often caused by restricted airflow from a dirty filter, blocked returns, or a failing blower. It resets automatically once temperatures return to normal.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit switch (auto-reset)\u003c\/li\u003e\n\u003cli\u003eContacts: Normally closed (opens on overtemp)\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eFits: AMEC960403ANAB furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe 150°F trip point is specific to this furnace's cabinet and heat-exchanger design.
