This normally-closed thermal limit monitors heat-exchanger and plenum temperatures, opening the burner circuit if the furnace overheats due to restricted airflow, a dirty filter, or blower failure. Replacing a failed limit with the exact OEM part restores reliable, code-compliant high-temperature protection.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 20162903\u003c\/li\u003e\n\u003cli\u003eType: Primary (auto-reset) thermal limit switch\u003c\/li\u003e\n\u003cli\u003eCutout Temperature: 150°F\u003c\/li\u003e\n\u003cli\u003eContact Configuration: Normally Closed (opens on rise)\u003c\/li\u003e\n\u003cli\u003eBrand Fit: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eApplication: Gas furnace safety limit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM 20162903\u003c\/strong\u003e is calibrated to Goodman's exact 150°F trip point and mounting footprint, ensuring the safety circuit behaves as the furnace was engineered. Generic universal limits may differ in cutout temperature, bracket geometry, or terminal orientation — leading to nuisance lockouts or improper protection. For a safety component, we recommend OEM.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Two mounting screws and two spade terminals.
