Replacing a tripped or open limit switch restores safe automatic operation.\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 (primary high limit)\u003c\/li\u003e\n\u003cli\u003eType: Automatic-reset thermal limit switch\u003c\/li\u003e\n\u003cli\u003eFits: AMH950704CXAB and compatible Goodman \u0026amp; Amana furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature safety shutoff\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe trip point and mounting bracket on a limit switch are safety-critical.
