This automatic safety control monitors heat-exchanger temperature and shuts off the burners if the furnace overheats — a critical protection against cracked heat exchangers, restricted airflow, and fire hazards. When a limit switch fails open, the furnace will not fire or will short-cycle on the blower.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003ePart Type: Primary high-limit switch\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature safety cutout\u003c\/li\u003e\n\u003cli\u003eCompatible Model: AMH950703BXAB\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are life-safety devices calibrated to a specific trip point and mounting profile.
