This safety-critical component continuously monitors heat-exchanger and plenum temperatures, opening the circuit to shut down the burners if the furnace overheats due to restricted airflow, a dirty filter, or blower failure. Installing the factory-spec limit protects your heat exchanger and keeps the furnace operating within UL-listed safety parameters.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eFunction: Primary high-limit temperature safety cutout\u003c\/li\u003e\n\u003cli\u003eType: Auto-reset bimetallic snap-disc control\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman WGFM195045S3BAB and select Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eCategory: Limit Switch \/ Temperature Control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM 20162904 is calibrated to the exact trip and reset temperatures specified by Goodman, ensuring correct furnace lockout behavior and full compatibility with the control board.
