This safety control monitors the temperature in the heat exchanger area and shuts off the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or a failing blower. A properly functioning limit switch is essential to prevent heat-exchanger damage and unsafe operating conditions.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \/ Amana AMEC961005CNAB gas furnace\u003c\/li\u003e\n\u003cli\u003eFunction: Cuts burner operation on overheat\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman limit switch is calibrated to the exact 150°F trip point and matches the factory mounting bracket and terminal layout.
